I'm surprised nobody has pointed you to the "Show Your Solarforce" thread yet. It can be seen here:

... The great thing about Solarforce L2s is that you can get a good quality light for $20 then put whatever P60 drop in you want from anywhere from $15-$90 depending on what you want (good XP-E for throw, 3 level, pushing 250 lumens for less than $20). Their are numerous ways to customize your light or upgrade it, especially the light output, which is a big one for me. As fast as the LED technology is growing, it makes sense to me to be able to upgrade the light down the road with out having to buy a whole new light each time. Plus you can have different drop ins to use depending if you want a huge amount of lumens or better run time, throw or flood, or a mixture of all. It can use CR123x2 (L2m only needs one), RCR123x2, 1x18650, or 2xAA if you use a small extension. This is what is making this light so popular. A quality light (maybe not a primium, depending on who you ask, but doesn't have the premium price tag either), with a huge amount of options and upgradability. Check it out. If you want to buy one there are places on line. I will be glad to recommend some places should you decide to go that way. Just PM me. Oh, and did I mention it comes in 3 different colors in case you don't want black?
P.S. This is a long thread. My list of Solarforce L2s is on page 27 post #781, seen here

You will notice different switches, clips, lengths, heads, bezels, P60 drop ins, a serious throw head, a lamp head, and every piece is interchangable with other L2 lights.
