Robertson 2P20158 ISL296T12MV Pak of 10 Fluorescent eBallasts for 2 F96T12 Lamps, Instant Start, 120-277Vac, 50-60Hz, NBF, HPF, (for HO lamp Applications The Recommended Ballast is The PSB296T12HOMV)

Excellent product - purchased twenty for driving twin F96T12-75 watt bulb fixtures each - each performs perfectly - light weight with more than sufficient wire length. Ballasts arrived well packaged in a timely manner and in good shape. Good buy. Be sure to note the slight wiring difference - black & white to 120 ac line - single red to both pins on one end - two blues to opposite pins individually.

The best thing about this ballast, besides the absolute best price anywhere, is that you can use it for 1 lamp or 2, HO, or Center pin light fixtures. Simple wiring instructions, Prime shipping, 120>277v...it just doesn't get any better than this. I use these in a commercial application, and so far the quality has been 100% out of the box.

Product does what it's supposed to do. Right on time I have installed 6 of these units that are working as expected. Wiring was easy considerably lighter weight than the original ballast. Good value

Great product, light weight and easy to install

As expected

Purchased a ten pack last week . Not happy all all !! I never write reviews but I spent hundreds of dollars on 10 ballets /20 x 8/foot bulbs and few hours of electricians time and only 4 of 10 work correctly ??We switched out bulbs and ballest and I had to run to lowes while electrician was present to figure out new GE ballets work great. These Robertson made in China ballest are junk! I'm not sure if Amazon will take back ?? Never returned anything but I have a few hundred buck down the drain on crap product from China ... One star at best !!!

So far so good. Had to replace 3of them in my shop with this wiring was different than old magnetic type but I can able to do it without problem.I will updated how long it will last.

I already used 4 piece and all of them were working good.I'll check the lifetime of them and let you guys know it.
