Questions & Answers

Is it possible to use just one bulb with this? What happens if the other three bulbs burn out, or if I only use one bulb?

The ROBERTSON 1P20135 ballast is designed to run 4/3 F32T8 lamps in series, with each lamp operating independently. Even if one lamp fails, the others will continue to work because the circuit between them and the ballast is intact. br>However, if your application only requires a single lamp, the ROBERTSON 2P20116 ISU232T8120 BA Quik-Lamp is a good choice.

What's the difference between the 3P201135 and the 1P20135 from Robertson? Thank you for the ballast case; I was in desperate need of one. ?

The 3P201135 was nowhere to be found. I needed a ballast for four tube T8 bulbs, so I bought the 1P20135. Other ballasts have a different number of bulbs that they can run. They were only $9 each on Amazon, but they were $32 elsewhere. I hope this information is useful.

Is this a ballast with a pre-programmed start?

These are not slow-start ballasts; they are fast-start ballasts.

I'm about to place my third order
3/5

But. I bought my first pair in July of this year. So far, there have been no issues. I'm changing the t12s to t8s and eliminating the need for two ballasts per fixture.
- br>Editbr>I had to replace one of these ballasts, which was from the second batch, because it wouldn't light any of the fixture's four t8s. Checked the voltage to the ballast, which was 120 volts. After installing a new ballast, all four lamps were turned on. I'm thinking about dating some of the ones I've recently added. I'll get back to you if there's any new information.

I maintain all lighting at a small private school with 130 fixtures, each with four F32T8 bulbs, and I get a great deal
5/5

This is the most affordable price I've found for this type of ballast, and they've proven to be very reliable so far. However, even at this lower price point for ballasts, I've begun to transition to direct wire LED bulbs that don't require a ballast, as the LED tubes will quickly pay for themselves thanks to electric company rebates and lower LED tube prices.

This is a fantastic deal on some very dependable ballasts
5/5

This is a fantastic deal on these ballasts. For the buildings that I maintain, I purchased a box. We've installed six so far, and they've all performed admirably. We'll be back to buy some more because the light output is excellent.

Converting old T12 or T8 fluorescent fixtures to LED fixtures is a breeze with this kit. This is a less expensive and faster option.

Excellent value for money
5/5

Great ballast, easy to install, and appears to be well built; I would recommend any Robertson ballast; I've used many 4 and 2 lamp ballasts and have been very happy with them.

Excellent service at a very reasonable cost. Our 4 ft florescent store light fixtures and refrigeration cases needed to be replaced aftermarket.
