What can I say, It works great
It took just ten minutes install on a two lamp fixture and it works great. Quick start, no noise , perfect performance, you can't ask for more. Also, the shipping was very quick. Just a quality unit.

Don't throw out your old fluorescent light. This electronic balast makes it better than new.
It takes some time to install, but this electronic balast works great. The magnetic balast that this replaced was about 5 times heavier than this electronic balast. This balast fit into the space left after removing the old balast without any modifications. With this new electronic balast the lights come on instantly and with no flickering when the switch is turned on. It is a vast improvement over the older style magnetic balast.

Replaces my older,bigger, heavier ballast (which had a dif't P/N)
Replaced my old ballast -- which was much bigger and heavier. This ballast is specified for 2 T12 fluorescent tubes, rapid start (not instant start), 72 Watts max, same as my older, heavier, bigger ballast. Works great. I thought maybe I bought the wrong ballast because it looked so much smaller than the original. But, no, it has the correct specs.

Great replacement for heavy outdated ballasts.
This was a direct replacement for an Advance R2S35-4-TP, 40W T12. It's a 1/4 of the weight and fastens and wires the same. No humming noise, fast startup.

Good Deal!
Pricing was good. Instructions on ballast were easy to follow. Worked as it was supposed to. Much lighter weight than the previous ballast.

Easy-Peasy
An easy installation, just follow the directions ( which you have read BEFORE you started, of course!).

Perfect Fit
Even though the ballasts being replaced were antiques and had every little color remaining in the insulators, these wer a breeze to match up and install.
