My First impressions--- Very Good beam pattern with no rings, unlike the 1W 3AAA. Warm white color, output similar to SL 4AA luxeon, but with a brighter intermediate spill area, and smaller central spot, probably due the overly deep reflector. This light has gobs of throw! Its not much bigger than the CR123 Maxfire. My first test was with Energizer 850 milliamp rechargables. I am going to fully charge them tonight, and try to do a run time tomorrow. Hoping I can get 1.5 hours out of the set. Typical brinkmann construction. Seems much brighter than the Coast 3AAA's that my buddy has. I would rate this a 3.5 to a 4. I bought it from target for $29.99. Anyone else have one and love it? If you want a 3AAA light, forget the 1W and buy the 3W.
