Mine's a dud!!! - FOURSEVENS Maelstrom S12 Compact Flashlight 800 Lumens

Was soo dissapointed with mine after reading all the reviews and video's.I'm very savvy to high powered led lights as i've purchased about ten different mountain bike set-ups over the past 18 months.I know what 800 lumens should look like and mine was at best half that. It was only marginally brighter than my Quark AA2 at 200 lumens.I'm waiting to here back from the vender to get their feedback on my returned light.Clearly to me this should be a fantastic light at 800+ lumens,to bad i won't see for myself.
Pros: Should be very bright at 5amps.
Cons: Possable week driver?
