Rated 5 out of 5 by Parts2 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!

Rated 4 out of 5 by turk 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

Rated 5 out of 5 by Maintance411 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 CplTech 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.
