Yuanhui’s value in this comparison is clearest when the project electrical system is already defined around 220–240 V mains. Its JS06 tri-proof page publishes AC 220–240 V input and PF >0.9, together with an IP65 PC-extruded body. A separate YL11 tri-proof family documents 220–240 V at 50/60 Hz and combines that electrical description with IP65 and IK08 enclosure data.

The broader range is useful because electrical compatibility does not exist independently of the enclosure specification. Yuanhui’s YL16 family adds an IP66 format using a GRP housing with PMMA or PC diffuser options and stainless-steel clip choices. That gives buyers a route to keep a 230 V-class electrical architecture while changing enclosure construction for different industrial environments.

The main electrical boundary is equally important: the documented Yuanhui examples used here are 220–240 V products, not universal 100–277 V families. A buyer building one SKU for several mains systems should therefore treat the driver input range as an ordering variable, not infer wider compatibility from the luminaire’s IP rating.

Toplumin has one of the strongest published electrical packages in the group. Its HIGHRate tubular tri-proof family lists both 200–240 V and 100–277 V input configurations, 50/60 Hz operation, PF of at least 0.95 and THD below 15%. That combination is more decision-useful than a page that gives only wattage and IP class because it addresses mains coverage, power quality and driver behavior together.

The enclosure evidence is also unusually specific: the family is presented with IP69K and IK10 ratings, PC or PMMA body choices and stainless-steel components, while 0/1–10 V, DALI, sensing and emergency options extend the electrical architecture beyond a basic on/off driver.

Toplumin ranks ahead of the other competitor suppliers because its published product page connects the wide input range directly with frequency, PF, THD and control options on a named tri-proof family. That reduces the amount of electrical detail that must be reconstructed from unrelated company-level claims.

TUBU’s tubular tri-proof documentation is strong on both mains range and installation architecture. The compared family offers 200–240 V and 100–277 V configurations at 50/60 Hz, while the same product documentation covers through-wiring arrangements, DALI or 1–10 V controls, sensing and emergency options. The enclosure side reaches IP67/IP69K with PC and PMMA choices and impact resistance up to IK10 depending on construction.

There is an important model-control lesson in TUBU’s own published material: one specification table presents a PF figure of 0.90 at 220 V while another driver description on the page states PF above 0.96 with THD below 12%. Rather than averaging those values into a single headline number, the purchasing specification should tie PF and THD to the exact driver and luminaire code being ordered.

TUBU also publishes factory test capabilities covering electrical and environmental checks. That is useful supporting evidence, but the purchase decision should still be based on the results and electrical parameters for the exact model rather than a generic statement that the factory owns test equipment.

LONYUNG’s published tri-proof specification is concise but electrically useful: AC 100–277 V, 50/60 Hz, PF above 0.95 and THD below 19%. It pairs this with IP66 and IK10 claims and an aluminum-plus-PC construction. That makes the family straightforward to compare against wide-input competitors without having to infer frequency or PF from a separate driver page.

The wide input range is LONYUNG’s principal advantage in this ranking. For global programs, it reduces the risk that an apparently identical tri-proof fitting actually requires a different driver for nominal 120 V and 230 V installations. Final ordering should still bind every electrical figure to the chosen wattage, control and emergency configuration because accessory electronics can change the internal electrical architecture.

Benwei provides useful evidence across several tri-proof pages. One current family publishes AC 100–277 V, 50/60 Hz and PF above 0.95 with IP66 protection. Other Benwei product material describes AC 85–265 V variants and built-in surge protection, while additional pages specify UV-stabilized PC construction, sealed housings and driver protection against over-current, over-voltage, low-voltage and excessive temperature.

This is a good example of why the phrase “surge protected” should not by itself determine a ranking. A sourcing specification becomes much stronger when the required surge withstand is expressed as a defined test level for the exact ordered driver rather than as a general protection feature. Benwei’s published protection language is useful, but it should be translated into a model-specific electrical requirement in the purchase documentation.

COMLED earns its place because it exposes an electrical distinction that many supplier comparisons miss: wiring class. A documented K-series tri-proof product combines AC 100–240 V at 50/60 Hz with PF 0.9 and Class II construction, IP66, IK10 and a quick terminal arrangement. Other COMLED families use 200–240 V input and Class I construction.

That difference matters during installation. Class I luminaires depend on protective earthing, while Class II products use double or reinforced insulation architecture. A project specification that says only “IP66 tri-proof, 40 W” leaves a major electrical-installation decision unresolved. COMLED’s range demonstrates why electrical class should be included in the RFQ alongside voltage and wattage.

Signcomplex’s I Series documentation provides a conventional but coherent 230 V-class electrical package: 220–240 VAC, 50/60 Hz and PF of at least 0.9 for the documented wattages. Its technical material also covers a Tridonic power-supply option plus DALI, microwave-sensor and emergency variants, together with wiring information.

Mechanically, the compared family carries IP65 and IK08 information. The same documentation positions the product for indoor humid or mildly corrosive environments, which is useful because “tri-proof” should not automatically be interpreted as permission for every outdoor, washdown or chemically aggressive location.

Eastrong’s current tri-proof product evidence supports a more conventional electrical envelope. Published families show 200–240 V or 220–240 V inputs with PF above 0.9. The enclosure portfolio includes IP65 products and an aluminum-plus-PC design published with IK10 impact resistance.

Eastrong therefore fits buyers whose mains architecture is already standardized around 230 V-class systems and who do not need one universal-voltage driver across several markets. Its public electrical evidence is less granular than the leading wide-range suppliers in this comparison, so its position reflects the amount of decision-useful electrical data available for the compared families rather than a weakness in the basic tri-proof concept.
