Building LED lights from facts, no theories

[Bubbleblower]

That tone /12 of Phillips is the best UVB Ive seen, but unfortunatelly I dont find it here. Its listed on Phillips website, but no any distributor carry it

You can order them here. Shipping to Spain is â?¬ 17,44.
Here is a normalized spectrum of the lamp compared with 4 other UV sources.
UVB-leds are still VERY expensive unfortunately.

Building LED lights from facts, no theories I was going to post this at the Perfect LED Grow Light thread, but as some of what im going to post was posted 2 years ago on the stickied thread about LEDs and people still continue developing lights from wrong ideas, i think a thread about this topic is largelly needed. The main problem is related to efficacy of spectrums. When the firsts LED experiments at Overgrow, we work on the hypothesis that blue and red light are more effective. It was an appealing hypothesis that promises large Rating: 5
