The ballast runs off 120v or 240v but the bulb is the same there aren't 120 or 240 volt bulbs the ballast takes what ever voltage and converts it to what the bulb needs.

When the led's get to 10-20w apiece then they will be useful but not affordable so come back in ten years and the led's might be affordable enough and strong enough to grow compared to the new digital ballasts and supulse digital bulbs. If you are serious about what you grow you won't be using...
Save your money and buy a few cfl's. If the led light don't cost you 300.00 or more you are just wasting your time. I have seen them used as the par lights and the panels and you want to bring your plant growth to a crawl then go ahead and use the 50.00 led thats about all they are good for...
I have a 4.5' X4.5' area with 9-3 foot plants under a 1000w sunpulse 3k and it is a jungle after 4 week veg and 4week flower. I figure with 5 more weeks to go I won't even be able to get the door closed anymore. Thinking that 6 in the same area would be better or maybe cut the veg time in half...

I have the same machine and for me it works great 9 months a year but as I live on the frozen tundra for half a year it seems like during the coldest 3 months of the winter cloning becomes slow too almost impossible at times even though I have a climate controlled clone box. In April - December...
