I finally got my Romisen RC-N3 CREE Q5. I went with the CR123a rechargeable battery. I am using twofish lock blocks for mounting. I could not be happier. I ended up with 215 lumens 4 rechargeable batteries and charger for only $53.
Is only 3.5 inches long and puts as much light as a $230 Light & Motion Stella. Granted battery life is short
(an hour or so) but with 4 rechargeable batteries who cares. I am buying one for everyone in the family.
