breakaway Posted July 25, 2011 Report Share Posted July 25, 2011 Hi All, Came across these LED lights recently: http://www.trademe.co.nz/Building-renovation/Electrical-lighting/Lights/Exterior-lights/auction-393379464.htm Then searched it on ebay, and found it for $53 shipped to NZ due to some bad decisions made by the US financial sector, so figured why not? The only thing I'm wondering is which is better for plant growth? A color temp of "3000K-3500K" or "6000K~7000K"? Now I realise this is badly designed mass produced garbage with little to no quality control so the quoted color temps aren't really to be trusted, and this technology isn't quite as refined as T5HO / halides etc, but as I said - for the price, why not? The only question is - cool white or warm white? Quote Link to comment Share on other sites More sharing options...
the-obstacle Posted July 25, 2011 Report Share Posted July 25, 2011 6000-7000 will be better for plants. Quote Link to comment Share on other sites More sharing options...
Ira Posted July 25, 2011 Report Share Posted July 25, 2011 I suspect the light from them will be very monochromatic, but worth a try I suppose. Are you sure the ones you're looking at from Ebay will work with 220V? If not you'll have to pay more for a transformer. If they don't work and they are 220v at least you can throw them on your house and use them for what they're intended. Quote Link to comment Share on other sites More sharing options...
Phantom Posted July 25, 2011 Report Share Posted July 25, 2011 If you want more options, http://www.dealextreme.com has a lot of LEDs and most of it has free shipping. If you wanted the same thing but without the casing, they have them for US$14.10. But you'd need the US$11.30 driver to run it from 230V and a heatsink as well.

breakaway Posted July 25, 2011 Author Report Share Posted July 25, 2011 Nah don't want to faff about with choosing individual LEDs and drivers, or mains wiring. Really want an all in one solution. Quote Link to comment Share on other sites More sharing options...

kiwibrick Posted July 25, 2011 Report Share Posted July 25, 2011 I don't know about the bulbs, but the drivers in the kits are 110 & 240V Quote Link to comment Share on other sites More sharing options...
spoon Posted July 25, 2011 Report Share Posted July 25, 2011 I don't know about the bulbs, but the drivers in the kits are 110 & 240V should be sweet then the leds work off a much lower voltage which the driver sorts out for them Quote Link to comment Share on other sites More sharing options...
