[QUOTE="Fred W, post: 1274841, member: 3828"] Look closely at the beam cast photos in the linked article. It is pretty obvious that the LED lights are much less uniform than the Halogen lights are. I would say that this is due to the fact that the LEDS only broadcast light to the left and right, not in a 360 degree radial pattern like a filament does, and that is what the reflector was designed for. LEDs would seem to be better used in a refractive light housing (projector type lights), where the directional light is a bonus, vs. in a reflective housing designed for a filament (halogen) or arc (HID) light source, where the directionality is a problem to be dealt with. I bet most new automotive applications are doing just that. [/QUOTE]
