Customer Reviews

Rated 4.6 out of 5 by 34 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 ballasts with simple install First, I purchased 15 of these ballasts and all of them functioned flawlessly. I installed them a little over a month ago to replace my old T12 ballasts and bulbs. The ballasts come one instantly, produce no noise as opposed to the old T12 magnetic ballasts, and combined with the Ushio T8 bulbs I also purchased, produce more lumens of illumination as opposed to the old T12 ballasts and bulbs I had.. Installation was pretty simple and took me about 15 minutes per troffer for complete replacement of the ballast and bulbs. I used crimp connectors on the wiring from the ballasts to the light holders and wrapped with 1/2 overlapping Scotch 33 tape. For the power wiring, I used yellow wire nuts, again wrapped with 1/2 overlapping Scotch 33 tape. In summary, I would definitely recommend these ballasts. April 25, 2015
Rated 4 out of 5 by Easy to install and works great This is a great product used to replace the old magnetic ballast for t12 the new SYLVANIA Quicktronic 49947 for t8 (s) are much quicker to start and the T8 are much brighter and less power consumption, less heat from the ballast April 23, 2015
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
