Jean and others who have tried the Superbrightleds 3W Luxeon MR16, what seems to be the problem with fitting this lamp into the Optronics light? Is it simply a matter of being a bit too long? Also, those of you who have had experience with halogen lights, how would you rate the 3W Luxeon's output in comparison to halogen. Equivalent to 10W? 15W?

I keep looking at those rechargable spots. You can usually get a 500,000 or 750,000 for about $10. The only reason I haven't picked one up to try is that I am having trouble visualizing a sturdy, stable mount. It's one thing to clip on one of the lightweight Optronics lights; it's another to deal with a big chunk with the added weight of the battery. I suppose it would be lighter to use one of the kind with a 12V lighter plug that I could just plug into my battery box; the integral switch would simplify things. Those things are EXTREMELY powerful. You really would have to be careful to keep the beam aimed low so as not to irritate or blind oncoming vehicles.
