A T8 4 foot LED tube search can be matched to several catalog-listed waterproof luminaire families, but the terminology needs to stay precise. The available catalog uses 1.2m T8 LED tube wording rather than stating an exact “4 foot” tube dimension. For selection, the useful starting point is therefore the documented 1.2m configurations—not an assumed imperial conversion.
CIXI YUANHUI LIGHTING ELECTRIC CO., LTD, located in Cixi, Ningbo, China, lists these configurations within several waterproof luminaire families. The relevant catalog rows cover YH3, YH11, YH15, YH16, and YH17, with both one-tube and two-tube arrangements.
Reference Standard: Relevant material and performance testing standards should be confirmed for the exact candidate. The catalog describes company-level quality processes and test-laboratory capabilities, but it does not identify a T8-tube-specific performance standard for these 1.2m configurations.
Which Catalog Models Match a T8 4 Foot LED Tube Search Most Closely?
The closest catalog-supported match to a 4ft LED tube T8 search is the group of waterproof luminaires explicitly configured for 1.2m T8 LED tubes. The catalog confirms those metric lamp configurations, but it does not state that 1.2m is an exact four-foot tube dimension.
That distinction matters because search terminology and contractual product specifications serve different purposes. “4 foot” is useful buyer language for narrowing a search, while 1.2m is the wording actually printed in the product evidence. Treating the two as automatically identical would introduce precision that the source does not provide.
The catalog gives buyers a stronger selection path: identify the model families that explicitly contain a 1.2m T8 configuration, decide whether a one-tube or two-tube arrangement is required, and then obtain candidate-specific dimensional documentation if exact physical length is critical.
This creates a clear separation between three levels of information:
- Search term: T8 4 foot LED tube.
- Catalog-supported lamp wording: T8 1.2m LED tube.
- Exact physical dimension: still requires candidate-specific confirmation if an exact four-foot requirement must be documented.
The distinction is especially important when preparing specifications, quotations, purchase orders, or replacement requirements. A search phrase can help locate candidates, but the final buying description should preserve the dimensions and configuration language that the manufacturer actually documents.
The associated products are waterproof luminaires, and the catalog also describes enclosure-level characteristics such as PC body material and IP65 protection. Those characteristics belong to the luminaire assembly. They should not be rewritten as material or ingress-protection specifications of the removable T8 tube itself.
For a broader view of the relevant product category, buyers can review the T5 and T8 LED tube waterproof fixture range.
Verified 1.2m T8 Configurations Across YH3, YH11, YH15, YH16, and YH17
The strongest selection value in the catalog comes from its model-level configuration rows. Instead of treating “T8” and “1.2m” as generic category descriptions, buyers can connect those facts to specific waterproof luminaire references.
| Luminaire family | One-tube 1.2m T8 variant | Two-tube 1.2m T8 variant |
|---|---|---|
| YH3 | YH3-136T | YH3-236T |
| YH11 | YH11-136T | YH11-236T |
| YH15 | YH15-112T | YH15-212T |
| YH16 | YH16-136A | YH16-236A |
| YH17 | YH17-136(A/B) | YH17-236(A/B) |
These rows establish a useful fact that a broad T8 4 foot LED tube query does not reveal by itself: there are multiple catalog families containing documented 1.2m T8 lamp configurations, and each family includes a distinction between one-tube and two-tube versions.
The catalog wording establishes the T8 lamp type, the 1.2m lamp reference, the tube quantity, and the associated model identifiers. It does not establish tube wattage, lumen output, tube material, or an exact imperial dimension.
That limitation should shape the comparison process. A buyer should not attempt to rank these five families by brightness, energy consumption, optical distribution, or tube lifetime based only on the listed rows. Those characteristics would require additional candidate-specific evidence.
The model map is still valuable because it turns an imprecise search into a defined set of catalog references. Instead of asking generally for a “4 foot T8,” a buyer can identify which family appears relevant and then ask for the exact documentation associated with that model.
For example, an inquiry can state that the requirement is being evaluated against the catalog-listed 1.2m T8 configuration and name the corresponding YH model. That makes later discussions about dimensions, lamp specifications, and ordering details easier to trace back to a documented configuration.
Keep These Boundaries Visible During Selection
- A 1.2m catalog description does not by itself prove an exact four-foot physical tube dimension.
- IP65 belongs to the associated waterproof luminaire and should not be transferred to the T8 tube.
- PC body material describes the luminaire body, not the tube material.
These are not minor wording issues. Each prevents a fixture-level or search-level attribute from being silently converted into a tube-level specification.
Choose Between One-Tube and Two-Tube Catalog Variants
After identifying the appropriate model family, the next documented selection branch is tube quantity. The catalog contains both T8 1×1.2m LED TUBE and T8 2×1.2m LED TUBES configurations.
That means a buyer can make one evidence-supported distinction immediately: whether the intended waterproof luminaire configuration contains one 1.2m T8 tube or two 1.2m T8 tubes.
What tube quantity does not prove is equally important. A two-tube model should not automatically be described as having a verified brightness advantage, a specific energy-use relationship, a particular lumen distribution, or a different service life. The available evidence does not provide those tube-performance values.
A practical selection process therefore starts with the physical product requirement rather than an inferred performance result.
First, identify the required luminaire family or candidate model. Then confirm whether the project requires the catalog-listed one-tube or two-tube arrangement. Finally, request any remaining product information needed for the actual purchasing decision.
This approach is particularly useful when a 4 foot LED T8 replacement tube search is really part of a larger fixture-selection or maintenance task. A person searching for a tube may actually need to establish what the existing luminaire was designed to contain. The model reference and tube quantity are therefore more reliable starting points than simply assuming that every search result using similar length terminology is interchangeable.
The catalog also describes company-level quality infrastructure. It states that production processes follow ISO9001 regulation and shows facilities associated with EMC, ERP witness, temperature, IP65/IP66, dark room, dust-proof, high-low-temperature cycle, salt-spray, needle-flame, glow-wire, and integrated-sphere testing. These details provide context about the company’s broader testing capabilities, but the catalog does not define a T8-tube-specific QC sequence for the 1.2m lamp configurations discussed here.
That difference should be maintained when reviewing a candidate. A company-level laboratory capability is not automatically a test result for a particular T8 tube.
Items to Confirm Before Releasing an Order
- Match the proposed product to the exact YH model reference shown in the catalog.
- Confirm that the lamp configuration is explicitly stated as T8 1.2m.
- Confirm whether the selected variant is the one-tube or two-tube configuration.
- Request exact tube-dimensional documentation if “4 foot” must be contractually precise.
- Keep the luminaire’s PC body material separate from any claim about tube construction.
- Keep the luminaire’s IP65 rating separate from any tube-level protection claim.
- Request candidate-specific wattage information rather than inferring it from the model code or tube length.
- Request candidate-specific lumen information if optical output is part of the buying decision.
- Check that the quotation and purchase order preserve the same model and lamp-configuration wording used during approval.
This checklist keeps the confirmed catalog facts intact while directing unresolved requirements to the exact documentation needed to close them.
What Still Needs Confirmation Before Calling a 1.2m T8 Tube “4 Foot”
The central unresolved point is dimensional equivalence. The catalog explicitly supports 1.2m T8 LED tube configurations, but it does not provide an exact “4 foot” tube dimension.
For casual searching, those descriptions may lead buyers toward the same general product class. For a formal specification, replacement approval, or purchasing contract, however, an approximate search relationship should not replace documented physical dimensions.
The safest wording is therefore straightforward: the catalog contains 1.2m T8 configurations that are relevant candidates for a T8 4 foot LED tube search, while exact four-foot compatibility remains subject to candidate-specific dimensional confirmation.
Three other tube-level fields also remain unresolved in the supplied evidence: tube material, tube wattage, and tube lumen output. None should be filled in from assumptions, similar products, model numbering, or enclosure specifications.
This also explains why the associated IP65 PC-body waterproof luminaire information needs to remain separate. IP65 describes the enclosure-level protection stated for the luminaire. PC describes the body material stated for that luminaire. Neither becomes a specification of the T8 lamp merely because the lamp is installed inside the fixture.
A precise buying description should therefore preserve the following hierarchy:
Confirmed: T8 LED tube format, 1.2m catalog wording, one- or two-tube configuration, and the listed YH model references.
Requires further confirmation when relevant: exact imperial length, tube wattage, tube lumen output, tube material, electrical details, and any other candidate-specific lamp parameter not stated in the available catalog information.
For buyers comparing the available product families, the waterproof fixture information for T5 and T8 LED tubes provides the natural next catalog-level reference point.
The result is a more reliable selection process: use the “4 foot” phrase to define the search intent, use the catalog’s 1.2m wording to identify verified candidates, use tube quantity to narrow the configuration, and use exact candidate documentation to close any dimensional or performance requirements that the catalog does not state.
