H11 360 LED Lamps REFLEX 3D 35W Uniform Shadow‑Free Specific for Lens Headlights

The increase in brightness, + 150%, in lumens compared to a halogen is a parameter calculated with REAL data using an ULBRICHT sphere.

Choosing a kit specific for lens headlights when upgrading from a halogen to a superior technology (usually LED or Xenon) is not just about "stronger light", but optical precision.

If your headlight originally uses an H11 bulb but you want to fit a different system (or an optimised kit), here is why choosing a "lens headlight kit" is crucial:

1. Beam Control (Cut‑off)

• A lens headlight works like a cinema projector: a spherical lens concentrates the light produced by the source.
• The problem: Standard LED bulbs often emit light at 180° or with central shadows.
• The solution: Kits specific for lens headlights are designed to place the LED chips (or the Xenon bulb) exactly at the focal point of the lens. This ensures a sharp cut‑off line, preventing dazzling oncoming drivers.

2. Elimination of "Shadow Zones"

• In lens headlights, if the light source has a body that is too thick (typical of cheap LEDs), shadow cones form on the road. Specific kits use:
• Ultra‑thin body: To mimic the thin filament of the original halogen.
• 360° emission: To completely fill the inner parabola of the lens headlight without leaving dark spots in the illumination.

3. Heat Dissipation and Space

• Lens headlights are often very closed and tight.
• A specific kit is designed to manage the high temperatures that develop inside the projector, preventing the inner parabola from flaking or the lens from clouding over time.
• They often include small external drivers or flat fans to allow the original rear cap to close, keeping the headlight waterproof.
