## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome ballast
*by B***S on January 24, 2013*

I did a lot of research prior to purchasing and I'm really happy I went with a Quantum. I've been running this ballast 12 hours a day for the past 2 months and it's been excellent. It makes very little noise, and produces very little heat. There is a small fan in the ballast for cooling but you can barely hear it. It's an excellent product, and the dimming feature is great for seedlings. I switched from an old Coil and core ballast, and I'd never go back especially now that these have become so affordable. I run an Ushio 600w HPS in it and it runs like a dream.

### ⭐ DYSFUNCTIONAL, not ceiled in package and small cult/slice to extension cord.
*by D***. on September 14, 2022*

I bought two of these same 600w ballast and the 1st ballast put out about 60% less light than the 2nd 600w ballast I bought (my personal 4oow ballast puts out more light than the 1st 600w dysfunctional ballast). Nor was this same dysfunctional ballast ceiled in the packaging like the 2nd ballast was and it also had a small cut to the extension cord as well.I believe it's a hit and miss when you buy certain things off of Amazon. A lot of time one gets returned items from others and those items can be dysfunctional and resold (such as what I believe happened to me).Also, and most of all - You get what you pay for! These are not the best of ballasts, but they do work (at least I hope). If you want to grow really good stuff with durable products than I suggest, spend the extra money and go to a local grow shop and buy all your need's there!The 2nd ballast I bought Ive only had for one day so far, and it seems to work fine. Yet time will only tell how this ballast is to workout(?).

### ⭐⭐⭐⭐⭐ Works great and I have one of these that's 4 years ...
*by T***L on March 2, 2016*

Works great and I have one of these that's 4 years old (the older model) and its still going strong. With the built in fan, cooling fins, dimming, and high power factor (efficiency) there is really no reason to try and cheap out on the ballast at this price. These never get too hot and seem to make the bulbs last a while as well.
