If you are not familiar with 4Seven, Fenix, NiteCor Flashlights, you may want to check them out. Nice equipment. I have had 3 Fenix for over two years and two 4Sevens on order. Latest in Cree Emitters, good prices. On line discount code CPF8 for an 8% discount. www.4sevens.com Many are not much larger than the battery. I am getting Quark Mini to replace my Fenix L1T V2.0 as EDC. Twice the output!! Others are great for shirt pocket carry@ 160 lumens out the front. If you are seeking high output....Fenix TK 40 at over 600 Lumens. I have had this T1 for over 2 years and it is going strong.
