hey people
would like to try them out, if ooly to save my electric bill but having done the math they DONT WORK....
LEDs with Punch!
check this article out...this dude tests every led on the market...he says you will be lucky to get 20 lumens out of a watt (which incidentally will take you 8 leds to get to that watt) on blue, and 46 lumens per watt for red.....AND THESE ARE THE BRIGHTEST CURRENTLY AVAILABLE.. so if you want to get to 7000 lumens psf then your looking at 2,800 led's psf for blue or 1400 led's per red...
no doubt they are the future as ones in development at 150 lumens per watt, but your still going to need 900-1000 of the buggers psf;not worth a month swinging a soldering iron sadly...
you can get low energy now in different colours and 11w, 20w outputs but i worked out for my 13sq ft grow space would need 85 11w or 41 20w....and 500w is bad enough with energy prices rising....
anyone with any other ideas to get my bills down??
