These are the buggers I was talking about. Honestly I'm somewhat interested in these as I have done research on the effects of red light/far red light on phytochrome activity in plants. Rule of thumb. Never let your plant see far red light LAST before it's dark period. inbetween is alright but red light is great! I'm not saying only red light is good at the end of the light cycle. but never far red light. The research is obviously more complicated than that but to explain it would be partial mumbo jumbo to myself at my current experience and knowledge level and also mumbo jumbo to 99 percent of everyone else. lol
I think I'm going to buy one of these as well as a 2700 k bulb. I'm curious to see how the 2100 k bulb works as well. I know there are some plants that actually prefer far red light but not very many if im not mistaken.
My only issue with this, is that if you look at the specs of not only these bulbs but other hps bulbs and compare them to my cfl that I specifically picked from a wide variety of bulbs....
I found a 600 watt bulb that gives off 95,000 lumens. I figure thats about average for a horticultural bulb.
My CFL is 80 watts with at the very minimum 10,000 lumens. I'm being generously low with because I understand everyones biase against them.
7.5 x 80 Watts is 600 Watts.
7.5 x 10,000 lumens is 75,000 lumens.
Now keeping in mind that a normal cfl has a higher PAR than a normal HPS bulb. Even a higher PAR than most if not all Horticultural HPSbulbs.
So with my bulb being much more than your average CFL with a higher lumen output than even what I stated above... wouldn't it be safe to say that my CFL is almost as strong lumen wise and much better PAR wise. So other than the initial cost upfront of purchasing a nice cfl bulb and having to spend more money per watt for that upfront cost.... Isn't my CFL about a good (fuck the cost) if not better than an HPS or MH depending on the color temp?
Or is the penetration value of the HPS just that much better?
Although I will say I've seen 1000 watt HPS bulbs and I know they look like the sun itself. but my cfl is bright as a muthafucker as well. def gives you a headache and blinds you momentarily if you so much as look at it.
