Afternoon lads just had a look at those lights ic3 I seen the test thread & was still a bit unsure . Then I found this .
IMHO it does NOT perform as advertised by alot of posts I've read. It's simply just what it is...a 420 watt full spectrum light. It won't perform like an hps under any circumstances, and it is NOT equivalent to a 700 watt hps....not in a million years! I used the light for a full year....I gave it a good run, now it's in the corner being used as a veg light. What I would compare it to is a 6 bulb t5, pretty much the same results. When flowering I could never get the buds very dense....at any distance. It may work well as supplementation...in a greenhouse, but as a primary light...and especially for flowering.....I could buy 4-1k hps lights for the same price....complete. Just my opinion, but I never understood the difference until I used hps. It's a cheap light to run....but I'm willing to pay for results, and I'll take the energy costs associated with high powered lights any day! I've read alot about the light, and had hosebomber look over the specs and he said it just was not what the mfgr. claimed it to be. It may work out for hobby growers, but the initial cost isn't justified. I don't play around anymore and I get what I need to get the job done while staying in the black. Sorry to burst anyones bubble....but it is what it is.
