Good. I found a different truck supply web sire. Prices about the same. If the light were white would it be strong enough for a headlight? As I understand the physics of an LED chip the light comes out of the edge of the chip with something like a 90 degree spread. That spread is fine for a tail-light. A collimating or lense system is needed if one needs a narrower beam. Laser pointers completely correct the spread to give a very tight beam. Too tight for us. One bike supplier calls their system Opticube; marketing tactic ? Part of what I like about a six or seven inch wide light emitter is you can get s good amount of light down the road without the painful intensity of n H.I.D. system. Comments?
