Why is everyone complaining about cost? I have been searching for about a week for some good LED's I could use to try a grow. I live in the SW and temps will seen be over 100 every day. I have my cabinet in an oustide shed and it has perfect temps 8 months of the year. During the summer months I have to run an AC unit to keep the cabinet cool. Add up the cost of electricity, and replacement HPS bulbs and LED's pay for themselves within a year.

Here is an order I just placed recently.
1,000 of KTL053AxI-T, 632nm, 7800mcd, 120 degree angle, $38.33/K
2,000 of KTL051AxI-U, 660nm, 5800mcd, 25 degree angle, $35.38/K x 2 $70.76
500 of KTL050BUCI, 464nm, 4000mcd, 30 degree, $116.54 for 500
Shipping by EMS, $30.00
Total $255.63

Before I did more research, I had picked up some 400nm Violet, and 470nm 10mm blue with 40000mcd 15 degree. I will also throw in some Green for the hell of it.


That's $.07303 per LED, sounds good to me. Or should I just get 3K of the 660's?

I know I still have to buy the breadbord or PCB to solder them. But a good 400w HPS is about $200-400. I will save more than $200-300 this summer alone if I can grow with these.

What do you feel about my spectrum.
