Right now I'm running a 250w Lumatek Dig Ballast. I'm thinking of upgrading to 600w Cultureleux dimmable ballast. It can be set to 300w, 450w and 600w. I'd be running it on 300w for 1-2 grows. I'm planning to get a bigger grow box next year anyway, so i can use the same ballast and run it on 450w or 600w. I'm not familiar with the brand. It's the only ballast brand this one grow shop (actually big as a warehouse) around here offers and its about 40% cheaper than the dimmable Lumitek available in other shops. So, to buy or not to buy? Will it be OK to run a dimmable ballast on the lowest level during a whole grow? Is the efficiency of a dimmable ballast same as a normal digital ballast?
Not to buy..... Lumatec is known established name , on the top of that Lumatec ballast comes with 5 year warranty....
OK, lets say i get the lumitek... is it advisable to use the dim function on a 600w ballast, efficiency wise? Or will get more out of a 400w dig ballast?
The best ratio Lumen per Watt is from 600W setting. I do not think it will eat less energy if you dimm it... But i can be wrong...
