T1 Series H11/H7 Fan LED Headlight Bulb(Set/2pcs)

Nowadays, the diverse marketing tactics and the numbers war have always misled ill-advised consumers. 100W? 12,000 lumens? Top-secret LED chip? Once tested, you will find these lies. Light Performance:  Colight T1 headlight employs the massive & powerful 3535 LED chips, their small footprint allows for maximum lumen density and precision perfection. T1 headlight creates a white light of 5000 LM per pair at 40w which is 5x brighter than your original bulbs, even at 50% power. The biggest advantage is that the thickness of the aluminum substrate is only 2.5mm, very close to the thickness of the halogen. Heat Dissipation System: Heat management is crucial for lumen maintenance and reliability. The bulb's internally opposed 1.5mm copper boards extract as much heat as possible from the area surrounding the LED chips and transfers it to the radiator at the back of the bulb. T1 bulbs are built from the highest quality 6063 aluminum material originally designed for aircraft and spacecraft
