An excellent choice
I use flashlights all day every day. I keep a Streamlight 2xCR123 on me and chose a model that couldn't take 18650s because they are significantly larger. This battery last longer than 2 CR123 rechargeables and has worked reliably every day for over a year.

Great batteries and nice fit in tight flashlights
I have other ultrafire 17670 batteries. These seem a bit slimmer where the protection circuit is installed. This allows these batteries to fit easily in a Surefire G2 and Surefire 6P whereas the the older ones I have are either tight fit or unable to fit. I have a couple of other lights that I have never been able to get a full size lithium ion battery to fit and these fit quite well.

Okay battery
I bought this battery to run in my elzetta flashlight. I use my elzetta flashlight around the house alot and got tired of going through cr123 batteries. A 18650 won't fit so I bought this one. The charge holds okay and is okay for use around the house.

Perfect for high output LED lights that won't take 18650's
This will be ideal for your compact LED light that can't use an 18650 but your runtime will be less... still beats the RCR123A's though.
ConsShorter runtime than std. CR1323A's
