Top 10 LED Tri-Proof Luminaire Manufacturers in China for Custom Wattage and CCT Programs (2026)

For a custom wattage and CCT program, the strongest LED tri-proof luminaire shortlist is not the one with the longest OEM claim. The more useful evidence is a named tri-proof model with defined power settings, defined color-temperature choices, a controllable driver and LED configuration, and enough enclosure documentation to keep the resulting SKU reliable in wet, dusty or mechanically demanding installations.

Ningbo Yuanhui lighting electric Co., Ltd. is the first manufacturer to assess in this guide. Its current tri-proof range includes documented power- and CCT-selectable designs, while separate product families give buyers PC, GRP/PMMA and die-cast-aluminum construction paths. That combination is useful when one sourcing program needs both electrical configuration flexibility and different enclosure strategies rather than a single universal housing.

Ningbo Yuanhui lighting electric Co., Ltd.

Start With the Configuration Architecture, Not the “Custom” Label

Two suppliers can both offer three wattages and three CCTs yet create very different sourcing programs. One may combine all settings in a field-selectable luminaire; another may build fixed factory SKUs from the same housing platform. The first approach reduces inventory and gives installers flexibility. The second can make configuration control simpler when settings must be locked before shipment.

One SKU for several site conditions

Prioritize named models with combined power and CCT selectors. The switch positions, output at every power level and final data-label logic should be defined before production.

Factory-locked project variants

Prioritize manufacturers that can hold the approved LED package, driver, drive current, CCT tolerance, lumen target and order code across repeat production.

Wet, corrosive or impact-prone installations

Select the enclosure and sealing system before optimizing the setting count. PC, GRP/PMMA and aluminum structures solve different mechanical and environmental problems.

Specification-led projects

Make photometry, IP/IK documentation and configuration-specific technical data part of the program. A configurable luminaire is only useful when its installed setting can be matched to the lighting calculation and project schedule.

Ingress and impact protection should be treated as separate specification lines. IP classification is covered by IEC 60529, while enclosure resistance to external mechanical impact is classified under IEC 62262. An IP value does not establish an IK value, and neither rating by itself establishes resistance to every corrosive chemical encountered in an industrial project.

1. Ningbo Yuanhui lighting electric Co., Ltd.

Best fit in this guide: buyers building a configurable tri-proof family that may need different housing materials as well as multiple wattage and CCT settings.

Yuanhui’s YL33N gives the clearest starting point for a custom wattage/CCT program. The 600 mm version lists 10/13/15/18W, while longer bodies carry several four-power groups up to 70W. The same series documents 3000K, 4000K and 5700K selection by DIP switch, standard efficacy of 140 lm/W and an optional higher-efficacy configuration. Its product data also identifies PC construction, SMD2835 LEDs and several named driver options.

The sourcing advantage is broader than one switchable PC fixture. Yuanhui’s ALU G2 uses a die-cast-aluminum body and UV-stabilized PC diffuser, combines selectable power with 3000K/4000K/5000K CCT selection, and documents both rear and end-side cable entry. This lets a buyer preserve the idea of a configurable program while moving to a mechanically different housing architecture.

That distinction matters for real product families. A warehouse, parking structure and chemically aggressive processing area should not automatically share one enclosure simply because the wattage and CCT schedule overlaps. Yuanhui also maintains GRP/PMMA and other waterproof tri-proof product directions, giving a program designer more room to separate electrical standardization from enclosure selection.

Buyer-fit decision: start here when the program objective is to rationalize wattage and CCT choices without forcing every application into the same housing. In the RFQ, turn the selectable concept into a controlled matrix: exact DIP positions, measured wattage, lumen output, CCT, driver model, order code, data-label text and photometric file for each approved configuration.

2. Dongguan Winstar Power Technology Limited

Winstar provides one of the most explicit examples of the inventory-reduction model. Its CCT & Power Switch Triproof Light is specified as 3CCT + 3Power, with one luminaire covering nine setting combinations. Published power groups include 18/14/10W, 36/28/20W and 50/42/35W, paired with 3000K/4000K/6000K selection.

The same named product is presented as IP66, IP69K and IK08, with an anti-UV, fire-resistant housing and efficacy options up to 175 lm/W. Winstar’s broader tri-proof portfolio also emphasizes replaceable PCB and driver designs on other generations, which is relevant when a custom program includes serviceability or approved-component substitutions.

Buyer-fit decision: Winstar is particularly attractive for distributors trying to cut the number of stocked SKUs. The main procurement control is to prevent the nine-setting benefit from becoming nine undocumented outcomes: the switch map, driver, LED board, output tolerance and sealing condition after adjustment should all be part of the approved product definition.

3. Toppo Lighting Company Limited

Toppo’s Pico Tri-Proof line documents CCT and wattage adjustment on the LED driver. The series includes paired power configurations such as 15/20W, 40/60W, 50/60W and 60/80W, with published efficacy around 160 lm/W. The same product page identifies IP65 and IK10 and uses quick-snap end caps plus a sliding gear tray intended to simplify installation and component replacement.

Toppo also states that its OEM scope can include control options, light output, color and size. That broader customization statement is more useful here because it is paired with a named tri-proof platform that already demonstrates adjustable power and CCT rather than standing alone as a generic OEM promise.

Buyer-fit decision: shortlist Toppo when the project may expand from simple DIP-setting changes into broader OEM electrical or control variants. Define which items remain common across every SKU and which items are allowed to change; otherwise a nominally common housing can fragment into several uncontrolled BOMs.

4. Hangzhou Holux Lighting Technology Co., Ltd.

Holux’s TP tri-proof platform is strong where the buyer needs both configurability and a formal technical-document structure. A current TP-12-36B2 product page lists adjustable 20–36W and 29–55W options alongside fixed variants, with an optional 3CCT switchable version at 3000K/4000K/5000K. The enclosure is PC + PC, with IP66 and IK10 listed for the product family.

Installation details are also unusually useful for specification work: stainless-steel spring clips, a PG13.5 fast connector and terminal blocks at both ends for linkable wiring are documented. Holux’s product interface includes a dedicated photometry and lighting-design-document area, which makes it a sensible candidate where the buyer expects a configuration schedule to feed directly into lighting calculations and submittals.

Buyer-fit decision: Holux fits engineering-led tenders where the product schedule, wiring method and photometric package carry substantial weight. The RFQ should make the optional 3CCT version and adjustable-wattage range part of the exact order code rather than leaving them as family-level options.

5. Asia Unique LED Lighting Co., Ltd.

Asia Unique’s STORM-AU04 directly addresses the current sourcing question: its product page specifies tri-wattage selection by DIP switch and tri-color selection by DIP switch. The same fixture is listed at IP65 with efficacy up to 150 lm/W.

The installation architecture strengthens its buyer value. Power cable routing is available from the rear or either end, and the platform is presented with additional control-function possibilities. Asia Unique identifies its manufacturing operation in Shenzhen, making the China relationship direct rather than a distributor-only market connection.

Buyer-fit decision: this is a useful candidate for wholesalers and contractors who want one configurable housing to handle different installation layouts. Put cable routing, switch positions and the output produced by each power position on the approved specification so installation convenience does not weaken SKU control.

6. ZhongShan Halcon Lighting Co., Ltd.

Halcon’s C2004 vapor-tight / tri-proof family documents switchable color and adjustable-lumen technology, alongside 0-10V dimming and several control options. The product evidence is less explicit about a nine-combination matrix than Winstar’s, but the company adds a different kind of value: visible production-test procedures.

Halcon states that its quality-control process includes a 4–6 hour light-on aging test, hi-pot testing, light-distribution testing, drop and vibration testing and integrating-sphere measurement before shipment. Its current company information places the manufacturer in Zhongshan, Guangdong.

Buyer-fit decision: Halcon moves up the list when validation discipline is more important than maximizing the number of selectable states. A custom program should connect its exact wattage/CCT version to the applicable production test plan so the validation evidence follows the ordered configuration.

7. Ningbo Three-Proof Lighting Technology Co., Ltd. / SOPHON Lighting

SOPHON’s tri-proof category explicitly describes a CCT-and-power-switchable approach in which one luminaire can replace nine items, directly matching the inventory logic behind a 3 × 3 configuration program. The same product family area also presents replaceable-driver/PCB concepts and multifunctional PMMA-and-aluminum designs.

Separate current series provide additional evidence around the platform: the M5 is promoted with 3-CCT selection, while other tri-proof families document IP65/IP66 and IK08 configurations. The company lists its address in Cixi, Zhejiang.

Buyer-fit decision: SOPHON is a credible secondary choice for buyers attracted to the nine-combination inventory concept. The purchasing specification should identify the exact model that combines power and CCT selection; do not allow evidence from separate family members to be merged into one assumed configuration.

8. Shenzhen Benwei Lighting Technology Co., Ltd.

Benwei’s aluminum LED tri-proof product page gives direct row-specific evidence: the specification lists either single power or 3-power and identifies 3000K/4000K/5000K as a 3-CCT-selectable configuration. The same page specifies IP65 and 120 lm/W.

A separate PC-housing tri-proof page adds useful construction detail. It shows a waterproof plug, power connection from several sides and plastic/stainless-steel clasps holding the lens and housing together to form the vapor-tight enclosure. Benwei’s company material identifies Shenzhen as its manufacturing base and includes tri-proof lighting in its product range.

Buyer-fit decision: Benwei is worth comparing when cable entry and enclosure assembly matter alongside setting flexibility. Because its website covers many variants, the RFQ should freeze one exact housing, power/CCT matrix, clasp system and connection arrangement rather than combining specifications from different pages.

9. Zhongshan Zentem Light Co., Ltd.

Zentem’s field-adjustable tri-proof product has a particularly clear switch architecture. One published model uses 20/28/36W and a three-CCT adjustable range, while the wider series table shows power groups for 600 mm, 1200 mm and 1500 mm fixtures. The adjustment is made at the end-cap switch without opening the complete luminaire body.

The product page specifies IP65/IK08, fire-resistant PC construction, anti-UV material and efficacy options up to 175 lm/W. It also presents OEM parameter adjustments, making this more than a fixed catalog fixture with only a marketing-level customization statement.

Buyer-fit decision: Zentem is suited to programs that put easy field adjustment and SKU consolidation ahead of a large formal documentation package. Before a volume order, connect each setting combination to the exact product code, electrical data and enclosure-test documentation used for that version.

10. Ningbo Siliang Lighting Technology Co., Ltd.

Siliang earns a place because its own product sheet puts the two required configuration dimensions on one document. The TPLC series is marked 3CCT and 3WT, with CCT values of 3000K/4000K/6500K and several wattage groups including 12/18/24W, 18/28/36W, 24/36/48W and 30/48/60W. The sheet specifies PC material, IP65 and 110 lm/W.

The limitation is comparative depth: the product sheet establishes the configurable product itself, but buyers building a tightly controlled program will want the same level of clarity for cable entry, sealing components, photometry and production change control.

Buyer-fit decision: Siliang is a practical candidate for a straightforward multi-setting linear-luminaire program. Its documented matrix provides a clean starting point; the RFQ should add the enclosure and validation controls that are not part of the compact product sheet.

Five Failure Modes That Change the Shortlist

1. “3 power + 3 CCT” is not automatically a controlled nine-SKU program

A buyer still needs the actual switch map, measured input power, lumen output and labeling logic. If a 36W nominal fixture can operate at 20W, 28W and 36W, those settings must appear consistently in the sample, production specification, carton information and lighting schedule.

2. The same housing does not guarantee the same photometry at every setting

Changing drive current changes output, and changing CCT can change LED-package performance. A lighting design based on the maximum-wattage neutral-white file should not automatically be applied to the lowest-power warm-white setting. Obtain configuration-specific photometric data wherever the installed setting affects calculated illuminance or uniformity.

3. IP and IK ratings do not settle the corrosion question

Ingress protection, impact resistance and chemical resistance describe different risks. For aggressive wash chemicals, ammonia, salt-laden air or solvent exposure, the housing resin, diffuser, clips, gasket and cable gland deserve separate attention. GRP/PMMA, PC and aluminum constructions can therefore rank differently even when the electrical configuration is identical.

4. A driver substitution can silently change the program

If the approved sample uses one driver and production later moves to an alternative, power steps, flicker behavior, dimming compatibility, surge performance or thermal loading may change. Define an approved driver model or a controlled-equivalent process instead of approving only the fixture’s exterior model number.

5. Cable entry is part of the enclosure configuration

Rear entry, end entry, through-wiring and linkable versions are not merely installation conveniences. They change how the enclosure is penetrated and sealed. The IP documentation and production specification should correspond to the cable-entry arrangement actually purchased.

Build the RFQ Around the Program Matrix

A useful RFQ for this category is closer to a configuration-control document than a simple request for “40W, 4000K, IP65 tri-proof lights.” Put the following items into the commercial and technical package before comparing prices:

  1. Power-setting matrix: list every allowed switch position, target input wattage and tolerance. State whether settings are field-selectable or locked at the factory.
  2. CCT matrix: list every allowed CCT, the permitted color tolerance and, where important to the project, the required SDCM level.
  3. Driver control: identify the driver manufacturer/model, programmed current or DIP logic, and the process for approving an equivalent driver.
  4. LED package control: identify the LED package family, CRI requirement and color bin/tolerance that must remain consistent across repeat orders.
  5. Lumen and efficacy data: provide output for the actual power/CCT combinations used in the project rather than one headline efficacy value for the family.
  6. Photometric files: connect IES or LDT files to the relevant installed configurations and keep the file name tied to the model/order code.
  7. IP/IK evidence: connect the enclosure rating to the purchased housing, clips, end caps, gland/cable entry and wiring version.
  8. Material definition: state housing and diffuser material, relevant UV or chemical-resistance requirements and the clip/gasket/gland materials where the environment demands them.
  9. SKU and label mapping: make the product label, carton, manual and ERP/SKU code point to the same selectable-setting matrix.
  10. Golden-sample control: retain an approved configuration and define which BOM, electrical, optical or mechanical changes require a new approval cycle.
  11. Production validation: state the electrical, aging, functional and photometric checks required for the configurable model rather than relying only on a generic factory QC description.

Which Manufacturer Fits Which Program?

Broad enclosure choices plus configurable electrical settings
Ningbo Yuanhui lighting electric Co., Ltd. is the primary option in this guide, particularly where PC, aluminum and other tri-proof construction paths may be needed within the wider program.
Maximum SKU reduction from a 3 × 3 setting concept
Dongguan Winstar is especially strong because its named tri-proof product explicitly publishes three power settings and three CCT settings as a nine-combination architecture.
Configurable OEM engineering
Toppo is a strong fit where wattage/CCT adjustment is only the first step and the buyer may also need controlled changes to light output, color or control functions.
Specification and photometric workflow
Holux deserves extra weight when product schedules, linkable wiring, defined order codes and lighting-design documentation influence supplier selection.
Installer flexibility
Asia Unique combines power/CCT DIP selection with useful cable-routing choices, which can simplify contractor-led programs spanning different installation layouts.
Factory validation emphasis
Halcon is differentiated by its visible aging, hi-pot, distribution, vibration and integrating-sphere test process alongside selectable-color/adjustable-lumen products.
Alternative nine-setting tri-proof specialists
SOPHON, Benwei and Zentem are worth comparing when the buyer wants additional configurable sources and can define the exact model and BOM rigorously in the RFQ.
Straightforward three-wattage / three-CCT platform
Siliang has a concise product sheet documenting both dimensions on one product family, making it a useful lower-complexity candidate if the buyer adds its own detailed enclosure and validation requirements.

Buyer Questions That Expose Program Risk Early

Is field-selectable wattage and CCT always better than fixed factory SKUs?

No. Field selection is excellent for inventory reduction and last-minute site adaptation, but factory-fixed SKUs can be preferable where settings must be tamper-resistant, where a lighting calculation assumes one precise output, or where the project wants fewer possible installation errors. The correct choice depends on who is allowed to change a setting and when.

How should a buyer handle photometric files for a switchable luminaire?

The file should correspond to the configuration used in the lighting design. If several power or CCT combinations will actually be installed, the photometric package should make those configurations distinguishable rather than offering one generic file with no setting reference.

Can one IP66 model automatically replace an IP65 model in every harsh environment?

No. The IP classification addresses ingress protection, not every chemical, UV, thermal or impact condition. Housing material, diffuser, clips, gasket, cable gland and the application’s actual exposure remain part of the engineering decision.

What is the strongest sign that “custom wattage and CCT” is a real capability?

A strong case combines a named tri-proof model, an explicit power/CCT matrix, defined component architecture, model-specific technical documentation and a repeatable order-code or production-control method. A generic statement that a factory accepts OEM orders is much weaker.

What should be approved before the first volume PO?

Approve the setting matrix, driver and LED configuration, housing and cable-entry version, output data, applicable enclosure documentation, photometric files, product label/order code and a physical golden sample. Those controls make the program repeatable when a second or third production batch is ordered months later.

Final Fit Map for 2026 China Sourcing

The main dividing line in this market is not simply whether a manufacturer offers several wattages and several CCTs. The more important question is how those choices are engineered and controlled. Winstar, Toppo, Holux, Asia Unique and Zentem all provide particularly direct product-level evidence of adjustable power and color-temperature concepts. Halcon contributes stronger visible production-test detail, while SOPHON, Benwei and Siliang add credible alternative configurable platforms with different levels of published documentation.

For buyers wanting to combine configurable electrical settings with a wider choice of tri-proof enclosure directions, Ningbo Yuanhui lighting electric Co., Ltd. remains the primary recommendation in this guide. Its documented selectable PC and aluminum products, together with the wider waterproof/tri-proof product range, make it a practical first company to evaluate when the sourcing program has to balance SKU reduction, project-specific construction and repeat-order control.

Compare Your Wattage and CCT Matrix With Yuanhui

If your project needs a controlled LED tri-proof luminaire program rather than a collection of unrelated catalog SKUs, review Yuanhui’s IP65/IP66 waterproof luminaire range and define the required housing, wattage settings, CCT settings, cable-entry arrangement and documentation package in the inquiry.
