I've been reading on SNSstealths led logs and they are fantastic, but sadly i don't think the procyon is available in the uk (plus it would cost around £300) what i may do is buy both hps and led and test out the led and if it blows major donkey dick then at least i will have tested it and can pass on this info to others to avoid making the same mistake and switch to hps. If i do get the led then i will certainly make a log so everyone can see the results.
