The brightness increase, + 120%, in lumens indicated compared to a halogen is a parameter calculated with REAL data with an ULBRICHT sphere.

Switching from old HIR2 9012 halogen bulbs to LEDs is one of the most popular (and beneficial) upgrades you can make to a car. It's not just about aesthetics, but also about efficiency and safety.

Here are the main reasons why it's worth making the switch:

1. Visibility and Safety

• The most obvious difference is brightness. While a standard HIR2 9012 halogen bulb emits around 1000-1350 lumens, a good LED kit can easily double or triple that.
• Color temperature: LEDs emit a cool white light (about 6000K), very similar to daylight. This is easier on the eyes and makes road signs much more reflective and readable than the yellowish light of halogens.
• Response time: LEDs light up instantly, unlike discharge lamps which require warm-up.

2. Energy Efficiency and Heat

• Halogen lamps work by heating a tungsten filament until it glows; this process wastes about 90% of their energy as heat.
• Reduced consumption: LEDs consume approximately 60-70% less energy. This reduces the strain on the electrical system and alternator.
• Less overheating: While LEDs generate heat at the base (dissipated by fans or heatsinks), they do not emit UV rays or excessive heat into the headlight's reflector, preventing the plastic from yellowing or cracking over time.

3. Extreme Duration

• A HIR2 9012 halogen bulb has an average lifespan of about 500-1,000 hours. A quality LED can exceed 30,000-50,000 hours. In practice, once installed, you likely won't need to replace them for the entire life of the car.

4. Modern Aesthetics

• Let's be honest: the old-school yellow light makes the car look dated. The pure white LED immediately gives the vehicle a more modern and premium look, aligning it aesthetically with the latest generation models.
