has anyone tried these
http://www.ebay.com/itm/261722416795?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT looks like an inexpensive way for a DIYer to try induction lights also fo red supplemental lighting these new diodes from bridgelux look interesting
http://www.ebay.com/itm/291234250536?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT they provide a much broader spectrum than 660nm diodes. I am currently testing a few as supplemental lighting to a standard 6500/3000k fluorescent mix during flowering.those inexpensive induction light caught my attention and was curios to know if anyone had tried them and what experience they had with them.
That induction light doesn't come with a ballast...add another hundred $$$, if you can find one. If you do find one, it's likely NOT FCC approved, and could become a beacon to your house. Plus, if you use the lamp without designing and testing a properly isolated Faraday Cage for it, you're just broadcasting your location to anyone with the know how to look for it.
I bought a 200 watt version with a ballast from a China sell off Ebay, fit it into a cheap stainless steel sink - modified to act as a light fixture - and had a relatively nice fixture for a DIY 'indagro'. Cost me in total, roughly $350.
But I could never get beyond the fear of the RFI, EMI, black helicopters, and 6x8 cells, to actually use it. Since I had no means of testing it, beyond seeing how much ground noise it was adding to the AC, I decided it wasn't worth the risk. I went with a proper T5 setup.
I think induction lamps are like Betamax...it was a good idea, but failed to catch on.
The future is LED.
As far as the LEDs you've linked, keep in mind that that's a lot of wiring to be doing, not to mention mounting them to some sort of heatsink. Plus, you should take the "Bridelux" branding with a HUGE grain of salt.
But as far as experimenting... they could be interesting if you have the time and the skill. You could wire 10 in series using a Constant Current supply capable of 700mA at 30-34vF. That will give you a 30 watt fixture at roughly 3000 lumens (running at full power). You could build 5 of these with 50 LEDs.
If you put them all on one fixture you'd have a 15000 lumen light fixture at 150w plus overhead losses of, perhaps, 30-50 watts, for a total power usage somewhere around 200 watts.
But you also have to be skeptical about them being "full spectrum". Between the red and the blue spectrum lies the virtually useless green spectrum, and if you check out RGB LED lamps at 10w, the green channel puts out considerably more total lumens, and uses more actual power than the red or the blue.
.......saw one recently and my God it puts out some heat.
