| A ballast keeps the current flow thru your bulb constant. Your household electricity(AC) pulses if you will, 60 times per second( This is what is meant by Hertz or Hz) The ballast ballances out this pulse. No it does not cool the bulb that I know of, so you need lots of moving air, FANS....Good luck, we are here to help

| Hey Fly.. the ballast is the part makes the bulb actually work and does not cool it. Check out the section on electronic ballasts on wikipedia.. Electrical ballast - Wikipedia, the free encyclopedia I think a lot of people like to cool tube style reflectors and a remote ballast. The cooltube lets you draw air through the tube.. usually about a 6" one.. and over the bulb.. then out of the grow area. That way.. you have no heat issues. If you look on hidhut.com they have some under the lighting kits i believe..

| I have been looking on ebay and found a 600w lighting system here. Now it says its an air cooled grow light so i assume that would mean it cools itself, but i have no idea if i need to hook a fan up to it or something along those lines, or does it just do it all by itself? Now if it cools itself does the ballast like regulate electricity or something?.Thanks.Peace. | ||||||||

| I was thinking something like this maybe? This is only a 400W.. but you get the idea. 400W HPS Digital Ballast, Bulb and Glass Tube Reflector Combo I bought one with a built in ballast and they are heavy.. so a pain in the ass to raise and lower. In hindsight, the remote ballast would be better in my opinion.

| That one is "air coolable" meaning you need to hookup a seperate fan to pull air over it. I did so with mine and it works well.. Quote:

| The "air cooled" usually means the reflector(hood unit) has a built in fitting on the outside where you attach a squirrel cage fan and a duct to blow air across the tube. Yes the ballast only regulates the flow of electricity... explained a little bit more in my first reply. Also there are two types of ballasts on the market today...digital and magnetic. Not sure if one is better than the other( I am a CFL guy personally because of space and heat issues, CFL's are all self ballast bulbs.) I do know that the digital ones are a little more pricey.

| What ever type of reflector you get, you will need to cool it. A 600watt light in a closet will need a good size fan to keep temps down. There's a formula in the faq section to calculate what size fan you will need. From my mistakes I have learned to then go one size bigger. Im sure you'll find many people here who are on their second or third fans, cause the first ones just were'nt big enough. | ||||||||

| . So the whole point of the fan is to cool the incoming air into the box so that cooler air is going towards my lights and plants right? and doing the formula i should use a 500CFM fan using Fman's idea of going a size up. Should i mount the fan on the top of my box where i can put an intake or on the bottom of the box for intake, or would the location of the fan not matter at all?Thanks.Peace. | ||||||||
