GE UltraMax Proline Electronic Ballast, 120/277 Volt Instant Start Ballast, Normal Ballast Factor, Ballast for Fluorescent Light (1) or (2) Lamp T8, Compatible with F32T8/WM and F17T8

I bought several inexpensive two tube 4 foot fixtures using 32 watt T8 bulbs from one of the big box hardware stores. The fixtures were inexpensive however some of the factory "Sunpark" branded ballasts have failed. I used this GE ballast as a replacement and it works fine. As other reviewers have mentioned there is a very slight delay of about 1/2 second for the light to come on once power is applied. I do not find this objectionable and likely only something you will notice if there are multiple lights installed so that you can spot the delay.This ballast was a few inches longer than the factory ballast. I removed the old ballast and used two #10 3/4 inch screws to secure the new ballast after drilling a small pilot hole in the sheet metal of the fixture. The old ballast had 7 wires for the bulbs as well as line, neutral, and ground. This replacement ballast has only 3 wires for the bulbs as well as power and ground. It was easy to install the replacement GE ballast. I was able to re-use the wiring in the existing fixture, just shorting together all leads at one end of the fixture and feeding those with one output from the ballast. The other two wires from the ballast feed the other end of each of the two tubes.

One of the two lamp overhead fixtures in my workshop would turn on if it had been turned off for a long time, but would not come back on if I turned it off and tried turning it back on after a few minutes. I found that the original ballast used in the fixture had been discontinued, so I opted for this product as a replacement. I ordered it on Prime, got it in 3 days, and installed it in about 20 minutes. The fixture now works perfectly every time I turn it on.

I have purchased and installed 4 of these. They are reasonably priced, directions for installation are printed on the ballast, you will need 3 screw caps to reconnect two blue and one red wires on the new ballast to the socket wires for the florescent bulbs. It takes about 15 minutes start to finish to set up ladder, turn off the light, remove clear plastic cover, remove bulbs, (if done carefully you can replace by only removing one bulb), take off metal cover by pushing the long sides towards the middle so that the sides of the cover are released from the slots they are in, use wire cutters to clip the 2 blue and 1 red wires, remove screw caps from black and white wires that connect old ballast to power feed wires, strip the ends of the 2 blue wires and one red wire to expose bare wire, remove screw holding burned out ballast and slide ballast out from slot, install new ballast and put the screw the secures the ballast back in, reconnect the five colored wires that were clipped to the same colored wires on the new ballast & secure the connections with screw caps, put metal cover back on, put bulb(s) back in, turn light on to verify connections are good, put plastic cover back on, remove ladder.

Used to replace my original ballast for a single T8F32 lamp in an under the counter fixture. The only fault I found with this unit is that in my opinion it is not "Instant Start". The lamp turns on in about 1/2 second where as the original ballast in this fixture started the lamp the instant the switch was activated. I guess it is all in how one defines "Instant". Other than this the unit looks well made was clearly labeled for an easy install.

These ballasts work perfectly to convert old T12 4 foot dual bulb fluorescent fixtures to accept T8 bulbs. Pay attention to the wiring diagram on the ballast itself and be sure your light sockets (called tombstones) are shunted. You can shunt non shunted tombstones yourself with a short piece of insulated wire run side to side or buy shunted replacements.

Bought this for 2 T-8 tube fixture that previously had a magnetic power supply. Wire configuration was exactly what I needed (two blue, one red, black and white and the wires were pre-stripped. Pre-stripping was a nice touch, but I cut off the excess wire to make a neater installation. INSTANT ON with NO HUM !!Perfect and highly recommended.

Wiring diagram is on the ballast. Price was right, so far it is working as it should.

The is a non-consumer (i.e. commercial) ballast, not intended for residential use. It meets FCC Part 18A regulations. Ballasts meeting Part 18B are meant for residential use, because they produce less radio interference.

Hooked this up to a screwed up 13 year old ballast. Followed basic wiring patterns (although new ballast used several less leads to either side of new ballast) and voila it worked like a charm. Also put in new LEW lights. Very nice results. Happy.

Work very well with my T8 LED Lamps. It was a little ticker than the old original Philips, so the "cover" had to be forcer a little to fit. The screw were exactly at the same spot. It's also a little slower (0.5 sec) than the old Philips (I can see all the others light open before this one), but does the job for me !
