Single-Beam Design
The L1-H11 is a single-beam bulb, meaning each bulb provides one lighting function. Its exact function depends on how the factory H11 bulb is used in your vehicle.
H11 applications can be used for headlights, fog lights or other factory lighting functions depending on the vehicle, so verify your original bulb number before purchasing.
L1 Series Technology
10,000 Lumens Per Pair
The L1-H11 produces 10,000 lumens per pair, giving customers a substantial upgrade from traditional halogen lighting while maintaining a properly focused light point. Lucas Lighting describes the L1 Series as providing three times or more the light output of original halogen bulbs.
Large & Correct Focus Point
The L1 Series is designed around a large, correctly focused light point, rather than simply maximizing raw LED output. This helps the bulb maintain a useful beam pattern when properly installed in compatible housings.
Reflector & Projector Compatible
L1 Series bulbs are designed for use in both standard reflector and projector-style housings. Proper bulb positioning and headlight aiming are still important for achieving the intended beam pattern.
Overbuilt LED Chipset
Lucas Lighting uses a high-quality, overbuilt chipset in the L1 Series with a stated 10,000-hour normal-use lifespan.
6V DRL Support
The H11 version supports compatible 6-volt daytime running light circuits using non-PWM systems. Lucas Lighting specifies approximately 20% of full output in 6V mode for 2025-production H11 bulbs.
Why Choose the Lucas Lighting L1-H11?
The L1-H11 is designed for customers who want a quality Lucas Lighting LED upgrade without stepping up to the higher price and additional technology of the L2 Series.
With 10,000 lumens per pair, a large focused light point, reflector/projector compatibility, IP65-or-better protection and approximately 10,000 hours of normal-use life, the L1-H11 provides a straightforward upgrade for compatible H11 applications.
For customers who want additional CANBUS functionality, IP67-or-better protection and a dedicated external controller, the L2-H11 provides the next step up in the Lucas Lighting lineup.
