I received my Evolva lights today. I put a 26650 battery in one, an 18650 battery in the other, and an 18650 battery (the biggest it will take) in my Archon D11V (same LED emitter as the Orcatorch D810 mentioned above) and compared them all. The 2 Evolva lights looked the same, to me, and they were quite a bit brighter than the Archon. The specs would suggest that the Evolva lights should be around twice as bright as the Archon and they looked it.
For the price, these Evolva lights seem awesome!
