Customer Reviews

Rated 4.6 out of 5 by 32 reviewers.
Rated 5 out of 5 by Super easy install and great price! I bought these ballasts to retrofit our old 4 bulb T12 troffers. The install was super easy and having to use only one ballast to run all four T8 bulbs is the way to go. The energy savings is a big plus and instant start is a huge plus! I will be buying more of these Sylvania Quicktronics! September 15, 2014
Rated 5 out of 5 by Great Product! Works like a charm and never had a bad one. February 26, 2015
Rated 5 out of 5 by Retrofitting Troffers to T-8 These are perfect for retrofitting T-12 Troffers to T-8, the electronic ballast not only reduce energy consumption by 80%, but unlike magnetic ballast they do not emit heat. The best part of this product is it is quick and easy to install, taking only 30 minutes to change the light fixture from a T-12 to T-8, which included new sockets ( a complete conversion).

Rated 5 out of 5 by packaging was worried about the packaging being bulbs but were delivered in excellent condition. December 25, 2014
Rated 5 out of 5 by Most efficient electronic ballast This ballast met our needs to have the most efficient fixture for the building. Some electronic ballasts at the "box" stores are less expensive but use more current. November 24, 2014
Rated 5 out of 5 by great product MINOR WIREING BUT WORTH IT. I HAVE INSTALLED SEVERAL OF THESE NOW AND WILL USE MORE TO REPLACE OLD STYLE BALLAST. November 17, 2014
Rated 5 out of 5 by Absolutely what we needed!! We used these to replace over 50 ballasts for our new Maker Space (Proto Makerspace) in North Houston, Texas. They were super simple to replace and wire up. They are also very energy efficient compared to what we had. The shipping was quicker than I expected and I definitely will be using 1000bulbs again. :) Roo November 4, 2014
