You mean like this?
"White LED Bulb" for the angle eye like this.
same color tone as a HID head lamp.
The right side is "BMW Genuine Bulb" and the left side is "White LED Bulb".
The light source is "High-Power LED" like this. This is "Luxeon Star" made by Lumileds.
This High-Power LED is about 140 times as bright as the usual LED.
Usual LED, "NICHIA NSPW-500BS"
Brightness: 9,200mcd(candela), Power: 0.72W(3.6V/20mA)
High-Power LED, "Luxeon Star LXHL-LW3C"
Brightness: 65lm(lumen), Power: 2.59W(3.7V/700mA)
65lm is 1,300,000mcd when Lumen is converted into Candela. (at viewing angle 10 degrees with "Collimator Lens".)
How bright it is!!
The right side is "BMW Genuine Bulb" and the left side is "White LED Bulb" which I made.
It consists of an aluminum pipe, an aluminum bar, and many aluminum L angles.
The aluminum L angles have a function as a heat-sink.
