Robertson 3P20160 Fluorescent eBallast for 3/4 F32T8 Linear Lamps, Instant Start, 120-277Vac, 50-60Hz, Normal Ballast Factor, HPF, Model ISL432T8HEMV

Easy installation, no surprises.

Ballast worked for 1 day with 4 LED bulbs. Dead. Checked power and bulbs.

Hooked up three so far. Saved a bunch of money over buying new fixtures. Change out was very easy and quick, non complicated. Glad I bought new tombstones to replace a couple of broken ones. They work great with instant on. One disapointment, I went to the Robertson Worldwide site to see who they were. The site stated that these ballast were union made in the United States. What i recieved said made in China. I made my decision to purchase on this statement by Robertson Worldwide. I will purchase these again, just don't care for the dishonesty.

I have six 4ft fluorescent shop lights that began to fail 1 at a time over a period of 2 or 3 years. I would change out the tubes, but that wouldn't help, so I would install a new ballast. Easy to install and worked great out of the box. Within a few months, the light would flicker a lot before coming on, something that a new ballast would again fix. I had another original light that began to fail, so same thing - easy to install, worked great out of the box, and in a few months that light would flicker a lot before coming on. BUY SOMEBODY ELSE'S BALLAST.

I got this part to replace the cheap one that came in an overhead lamp fixture which died within a year of original installation. This is a hopefully high quality, standard part which I hope will last longer than the original. I had a professional electrician install it as my talented brother-in-law wasn't available, but anyone with some understanding of basic electronics could probably install it. Highly recommended!

After our basement tubelight died, i decided to switch from T12 to the newer T8 bulbs. I ordered this ballast as well as the T8 socket holders (aka "tombstones"). I am not much of a handyman but i was able to swap things and the T8 works great. It is brighter now and i do not have to deal with the constant buzzing noise of the older ballast. People have pointed out the the older ballasts last longer than these electronic ones so i cannot judge the long term reliability yet. However, i am happy with the purchase and feel it is worth it

I needed to replace the ballast in a three-tube 48-inch light fixture and this worked fine. it was not exactly the same size as the old ballast but was easy to install and works fine. This unit can handle three or four tubes.

D.O.A. never functioned. I do run LED lights in my T8 fixtures but the "Advanced" quick start ballast I replaced this with has no issues at all with the same bulbs. Would not recommend.
