A five gallon pot is about 12" in diameter on the bottom, which means you may have up to 16 pots in a 4' x 4' area.Q: Can a lower wattage lamp be used with a higher wattage iPower ballast, and vice-versa?A: Different mismatched wattage lamp and ballast per light fixture may cause premature ballast and/or lamp failure, and is not covered under warranty. Please use the same paired wattage lamp and ballast per light fixture; the dimming feature is designed for the purpose of a lowering lamp output when needed.

Review: If your in need of a light ballast, here you go - Ordered this 600watt ipower ballast a day or two ago . Haven’t even received it yet and I’m already able to write a review. Full disclosure, I have never owned any other brands of lights or ballast . Been a grow for 10 years , with a few grows under my belt . I’m also pretty tight with most the larger growers in my area. Where to begin. Bought my first ipower ballast and grow light , and pretty much never looked back . The ballast this one will be replacing is just over 8 years old . And with a couple of grows on it . It’s on right now and running great . Did have it , what I call , blink out the other day . After 8 years and a couple of really good grows , blink out my dear friend. I only buy ipower lights and ballast. There a solid product, and at a really good price . It’s what I have known . And worked with over the years . Even converted a few other grows to ipower . Can’t speak for there customer service , mainly cause I never had to deal with them . Yet lol . There products work and thy don’t break the bank . And out of the , let’s say ten others I know , who also own and love ipower, no fires . Mike . I have had 3 ipower 1000 watt ballast, with there lights , and this will make number 4 , 600 watt ballast, and to this day , all but one I could plug in and thy would work right now . The one that wouldn’t , well , let’s just say your not supposed to bash them against walls while made . Not a spokesperson. Just a grower looking to help others do there grow . I know there other ballast out there , and probably some better then this brand . But for the price . And longevity , you can not go wrong . Grow on Update ; This ballast has a super lumens setting. My 8 year old ballast that this one was to replace , on the highest setting put out 51,110 lumens . This one , on the super setting, puts out 68,878 !! Love the super setting! Grow big !!

### ⭐⭐⭐⭐ Affordable dimmable ballast that comes with extra fuse and burns both MH and HPS bulbs .
*by C***1 on January 11, 2015*

This is my second one of these . Pro's they are quiet , use less electricity then a magnetic ballast as well as can tell and self switch between MH and HPS bulbs that are the correct size or 600 watts lighting either one . They also have 3 power settings or a dimmer switch . They come with a 5 year warranty in fact I am looking for my paperwork now as I had one burn out after 3 years of daily use . The first thing you check is the fuse and there are videos on youtube on how to do it . All you need is a flat blade screw driver their is a little drawer built in by where the power chord plugs in . You just put the flat end tip in where it fits together and pry it open ...very simple . Inside is a extra fuse they both slide out in the piece that is the drawer . You just switch the two and put it back together . The video says 50% of the time this fixes the lamp . In my case I found a bulb burned out so I replaced the bulb and still nothing where upon I changed the fuse without luck so I purchased this as they are very affordable as ballasts go. The setup lit up and works great now . In my case the 2 day prime shipping was a huge draw and worth the small premium to the best deal I could find anywhere online or local . I used the warehouse deals to save a little more money and nothing but the packaging was effected , just a crushed box . With the expense of shipping these warranties are so so as well as you don't have the time if you have plants to wait for the process to take place . I expect to see a drop in my electric use . Amazon says the warehouse deals do not have a warranty I will still register it and check with Ipower . The ballast was never used it was all wrapped in plastic with all the warranty papers only the crushed packaging . All and all I am very pleased though sad the original only lasted 3 years so I took a star off . I believe the capacitor or igniter went out . If initial cost is a consideration this is a solid choice and I found for my needs 600 watts with a dimmable ballast was the best choice though most prefer 1000 watts and the 400 is the least expensive there is plenty of information online to help choose the proper wattage for your application .
