Thanks, looking forward to seeing your test sharing.I bought a mars fc8000 with the 301b in it......our little cheap light is about 200par BRIGHTER! lol......granted the distribution is not as good, but whatever diodes are in it are bright and a great spectrum. I added uv/ir bars after playing with it on another light. Definite better smell and frostiness with that light....potency test is coming soon.
