I haven't reviewed one because I was not furnished with one and cannot afford to purchase one on my own.
That's why I do not have an evaluation of one.
That's my story, and I'm sticking to it.
I did a search for L7 but results were mostly U2, L5, L4, L6 and other SF incadescent.mmm This is strange. with all the flashoholics out there, I assume one would have L7 since so many people post pictures of theirs SF lights on this forum.
