For those unaware about rechargeable batteries. Here is some additional info you may want to consider.
If you have a Surefire or just about any light that runs on CR123s you can get some Soshine 3.0 Volt RCR123s and they work great. (I get mine from Banggood) This can save you a ton of money. You want to make sure you get 3.0 volt cells. However, some of the single cell LED Surefire lights will actually run a 3.7 volt (16340) cell fine. Also if you have a two cell light, you can try out 17670 EFEST cells. They are 3.7 volts. A lot of the E series LED Surefire lights that run two CR123s will run fine on a single 17670.
If you have a older Surefire Incandescent and want to upgrade the output, check out Lumens Factory. He has some nice Hot Wires. He even has some LED drop ins too that are a good deal for the money.
If I am running 16340s, 17670s, or 18650s my goto cell is the Efest. I get them from Mtn Electronics or RTD Vapor.
Also know the differences between Protected (PCB) and non protected cells. Button top and Flat top too. Know that protected cells are slightly longer and may not fit all lights due to length. I would suggest Button Top Protected cells for most lights.
NEVER EVER EVER buy batteries with FIRE in the name. They are typically Chinese junk. Some look to be filled with drywall. I am not kidding. To be safe, don't buy batteries from either Ebay or Amazon. They are almost always not the mAh they claim and are counterfeit fakes. Once again, Mtn Electronics or RTD Vapor and you are safe. I can't stress the importance of buying quality cells from a reputable dealer. You can also harvest your own Unprotected, flattop 18650s from old laptop battery packs. Google that if you are interested. It is easy.
I run either Nitecore or X-Star chargers.
I probably have close to 75 Surefires and a 100 other lights. I have been collecting for years, and like you guys buy custom knives, I have dozens of custom lights.

Some of the best out of the box lights you can get are from Vinhnguyen54 (Vinh) over at Candle Power Forums. Here is his website: SkyLumen.com
I see one of the folks in this thread listed some. His lights will end with a (vn) in the name. So, for example, if it is a Nitecore Headlamp, it will read HC90vn. <---BTW, the best headlight I have ever owned. IF you want a great performance light that will impress you and others, check out Vinhs work.
Hope that helps some of you folks who may be just getting into lights or just curious about them. There of course is a endless amount of info on lights.
