Review: Works great and I have one of these that's 4 years ... - 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. Review: Terrible product - First ballast did not work, ordered replacement ballast. That did not work. Returning both and going to a different manufacturer. Yes the bulb was checked and it works on a different ballast ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002T0H24G | | ASIN | B002T0H24G | | Best Sellers Rank | #593,361 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #519 in Electrical Ballasts | | Customer Reviews | 3.7 3.7 out of 5 stars (122) | | Date First Available | October 15, 2009 | | Date First Available | October 15, 2009 | | Is Discontinued By Manufacturer | No | | Is Discontinued By Manufacturer | No | | Item Weight | 6.6 pounds | | Item model number | QT600 | | Item model number | QT600 | | Manufacturer | Hydrofarm | | Manufacturer | Hydrofarm | | Product Dimensions | 14.6 x 7.1 x 3.15 inches | | Product Dimensions | 14.6 x 7.1 x 3.15 inches; 6.6 Pounds | ## Images ![Quantum QT600 Dimmable Ballast, 600W - Image 1](https://m.media-amazon.com/images/I/6171KXIX7QL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.
