Rated 5.0 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by A great upgrade We used these ballasts to upgrade from the T12 bulbs we were using. It took one ballast to replace two in each of our four bulb lights. They were easy to install, and the wiring diagram showed how to change the wiring to accommodate the new ballasts. April 14, 2015
Rated 5.0 out of 5.0 by Upgrade to T8 Fluorescent lights I replaced my old 4 ft Fluorescent lights with the T8 lamps. Shut off the circuit first. You cut the wires pull the old ballast and put in the new ballast. I used electrical splices so you strip the wires and crimp in the splice. The hard part is making sure you cross the positive and return wires, not much to it really. My light fixture holds 4 lamps but with the output of the T8 lights I only need two per fixture now getting more light and saving a bit of electricity They seem kind of expensive but that seems to be the going rate. I highly recommend that everyone upgrades to the T8 lamps. March 10, 2015
Rated 5.0 out of 5.0 by The ballast The ballast that I purchased did the job as expected. I ha an electrical engineer install the ballast. The ballast installation took care of the problem. This ballast is a good replacement for the original ballast that is discontinued. February 10, 2015
Rated 5.0 out of 5.0 by Works as it should. Easy fix to bad ballast. easy way to fix a bad ballast. A lot cheaper than replacing the light. If you have decent wire strippers and cutters it takes about 5-10 minutes to replace. One thing to think about is it doesn't include wire nuts and if you follow instructions (and this is the easy way), you need them. Not a problem for someone like me that has hundreds in the garage. If you are not one to have wire nuts on hand pick up 8. The need to be big enough to hold two wires. March 29, 2014
Rated 5.0 out of 5.0 by Ballast There isn't much you can get excited about when it comes to a fluorescent ballast except that it was $13.00 les than Ace Hardware. March 18, 2014
Rated 5.0 out of 5.0 by Ballast Easy to install. Lightweight. Cheep and works great. July 8, 2014
Rated 5.0 out of 5.0 by Nice ballast at a good price. Bought this to replace a 20 year old ballast no longer made. Easy to install, fit perfectly, and worked as required, instant on. Now to see if it lasts. June 17, 2014
Rated 5.0 out of 5.0 by normal looking it worked fine the electronics staff (a woman named Bertha?) helped me a lot in understanding the wiring schematic. dont think i could have done the job without her help May 27, 2014
