It will not work. It is for commercial electrical service 277 volts. You will burn out the ballast.

No pissing contest here....Suppose I could have phrased it better.....Voltage must be kept constant.

You seem to have some basic understanding of electric and its applications, I myself have been an electrican for a number of years. Here in the US voltage is a constant 120/240 277/480 depending on the transformer configuration other voltages such as 208 are available. But the voltage must be...

They do not make 240 volt flour. ballasts. However they do make 277 volt and 208 volt ballasts but these are limited to commercial applications.

Most people have trouble understanding the meaning of both voltage and amperage....I'll try to explain the best I can. I think this may be an easy example relating it to water..... Voltage is equal to gallons per minute(gpm) (this number is constant) Amperage is equal to pressure at witch (gpm)...

A #14 gauge wire is only rated at 15 amps. For 50 amps you would need a #6 wire. However basic Ohm's Law tells us that if you double the voltage you cut the amperage in half. In other words if you run whatever appliances you have at 240 volts you will require only 25 amps. Any electrical...

Very True, hehehe.......My grow room is going to be approx 5x5 with a 600w HPS. 4 maybe 5 plants tops, think I will need a carbon filter also??

I have one of these at home....was wondering if it would help with odor. Anyone try this before?? http://www.honeywellcentral.com/product/0-90271-50150-4.html

Thanks for reply. Window is basement type 28 x 16 I think, but window is going to be in grow room....do you really think Ill need duct to move air in such a small room?? Also have you ever tried one of those air purifier things for help with odor??

Bump......Any opinions on my venting...temp is my major concern

Iam about to try my first grow and planning my grow room. It will be in basement approx 5x5 600w hps the area has basement window, so I was thinking of using one of those dual window fans that can vent and give fresh air controlled by thermo. My question is I have one of those honeywell air...
