Cost: $26.99 (Currently unavailable...)
Color: 6000K (slight bluish tint)
Lumens: 3,000 (Bright!)
Moving Parts: None, uses braided bands of steel(?) as a heat sink, nothing to seize up, no reason for it to overheat, and burn out.
Difficult to install: Not at all! Has a plug which matches the H4 bulb of the bike, perfectly.
Would you recommend/buy another: in a heartbeat, Baby!

Pattern on Street, at Night: identical to the Halogen H4 I pulled out; I swapped the two, back and forth, to compare the beam pattern, then I took it out at night, to verify it was 'normal' in light pattern... It was.
Bottom Line: Buy it, when it is available again! Carry a Halogen back-up, but only as a back-up. Cheers!
