T08 Series H4 LED Headlight Bulb with Optical Lens

The T08 Series H4 LED Headlight Bulb with Optical Lens is a compact dual-beam lighting solution for compatible H4 headlight housings. Four customized 3570 LED chips work with the optical lens structure to create separate high and low beam performance in one replacement-oriented bulb. High beam output is rated at 2,751LM / 37.48W initially and 2,085LM / 30.75W in stable operation. Low beam output is rated at 1,368LM / 24.50W initially and 1,200LM / 23.89W in stable operation. Operating on DC 11V-18V, the bulb draws 2.8A ± 0.28A for high beam and 1.78A ± 0.18A for low beam at 13.5V. This balanced configuration gives wholesale, private-label, OEM, and ODM programs a clear dual-beam option with a compact optical and thermal design.

Plug-and-Play

T08 Series H4 is designed around a plug-and-play installation concept for suitable H4 applications. Its compact body follows the original bulb location, helping installers fit the lamp without cutting the headlight housing or making permanent changes to the assembly. This non-destructive installation approach makes the product straightforward to present in distributor catalogues and replacement-lighting programs. The bulb is intended to work within compatible lamp housings rather than relying on an oversized conversion structure. Because rear clearance, dust-cap space, bulb-retaining methods, and connectors can differ by vehicle, fitment should always be checked before installation. Once correctly matched, the compact layout helps preserve a clean installation and supports an efficient upgrade path for vehicles using H4 headlight bulbs.

Perfect Fit

The Perfect Fit concept is built around a 1:1-scale replacement structure. T08 Series H4 is designed to position its light-emitting area close to the original H4 halogen bulb position, helping retain the intended relationship between the bulb and the headlamp optics. This precise geometry is important for dual-beam applications because high and low beam functions both rely on the original housing to guide the light. The compact structure also supports use in headlamp assemblies with limited space behind the bulb. Instead of presenting the product as a universal oversized LED conversion, the design focuses on a close-fitting replacement profile that works with compatible H4 headlight layouts. This makes it an appealing option for B2B customers who value an orderly installation and a familiar bulb-to-housing relationship.

Drive Safer

T08 Series H4 uses an optical lens structure to support controlled light placement and a sharply defined cutoff line in a correctly matched headlamp. The lens-focused design works with the four customized 3570 LED chips to create a more organized illumination pattern for both high and low beam operation. For low beam use, a defined cutoff helps keep the light pattern orderly. For high beam use, the compact optical arrangement supports forward illumination where it is needed. Actual beam performance depends on the original headlamp optics, vehicle condition, installation quality, and lamp aiming, so the finished beam pattern should be checked after installation. By combining a dual-beam H4 configuration with lens-focused optics, T08 Series H4 gives distributors and brands a clear product story centered on controlled lighting rather than generic brightness alone.

Advanced Cooling System

The T08 Series is equipped with an integrated high-speed turbofan, an ultra-thermal heat-pipe cooling system, and a die-cast aluminum-alloy body to manage heat during operation. The turbofan increases cooling capacity by up to 150%, while the heat pipes transfer heat away from the upgraded LED chips, specified for this configuration as customized 3570 LED chips. Working together, these components create a continuous path for airflow and heat dissipation around the compact lamp body. The die-cast aluminum-alloy structure provides a durable thermal foundation that helps release heat through the integrated cooling layout. This combined system helps maintain stable operating conditions and consistent light output during extended use while preserving the compact 1:1 replacement structure of the bulb.

Certification

T08 Series H4 is positioned for automotive lighting programs where product documentation is an important part of product selection. CE and RoHS documentation can support configuration review for wholesale projects, private-label product ranges, OEM cooperation, and ODM development. Before a market-specific release, buyers can confirm the current documentation scope for the final configuration and destination market. This helps distributors and brands align product communication with their local requirements while presenting the core advantages of the series. With its compact 1:1 replacement design, dual-beam performance, optical lens structure, sharply defined cutoff concept, and integrated thermal management, T08 Series H4 offers a complete H4 headlight solution for customers looking for both practical fitment and differentiated product presentation.
