Unsure of brand, but from all that I have owned this one is the best. Runs off 1 CR123a(not included) and has a fairly bright LED bulb. Pressure switch take a bit of getting used to for right handed shooters, but should be very easy to learn. Price us $55 shipped(+3% if you send G&S) **Will ONLY trade for a EXPS3-0 in black**
