Hello alangski, these bulbs should be a replacement as long as your Sylvania bulbs were using an instant start ballast as well.

Customer Reviews

4 ft. T8 32-Watt Cool White (4100K) ALTO Linear Fluorescent Light Bulb (30-Pack) is rated 3.5 out of 5 by 20.
Rated 2 out of 5 by from High out-of-box failure rate Bought 3 cases of these bulbs to do a refresh of our gym at my church. So far, I've had a 30% failure rate right out of the box. Bulbs were dark-patched or flickery like the old ones that had to warm-up on a magnetic ballast. Brand new ballasts and did bulb swapping to make sure problem was with specific bulb and not some other factor. If I was not well into this project, I would return all the bulbs and go with a different brand. I may still do that with the remaining ones.

Rated 5 out of 5 by from Great Purchase Great purchase. Would recommend this product to anyone interested.

Rated 3 out of 5 by from Tubes are good, but packed badly so some arrived broken. The summary says nearly all of it. I called when I opened the box and found what seemed like missing tubes. No, they were at the bottom of the channels, broken. I called immediately, and replacement tubes were supposedly to be shipped immediately. I realized a couple of days ago that they have never arrived. If the tubes had been in stock at a store I would recommend, but not if you have to have them shipped.

Rated 1 out of 5 by from don't even think about it! I bought 4 cases knowing the reviews were bad. The first case we opened 2 out of the first 15 work the rest were real dim. the next case we thought we would try and the same thing. these bulbs are junk and wasted a good amount of my day getting replacements.

Rated 5 out of 5 by from great lights the lights are inexpensive, they seem to last a long time in a commercial setting, the light is just right
Date published: 2015-02-11
Rated 1 out of 5 by from 33% Garbage I know with that low-mercury bulbs need a few hours to achieve full brightness, but one third of the bulbs I've tried out of the box are total failures and never go past dim. Those that do light up are inconsistent in color, some being warm and others being bluish. Don't waste your time on these.

Rated 4 out of 5 by from Cool white lights The lights are quality manufactured and are easy to install. They provide excellent illumination for the cost.

Rated 5 out of 5 by from good product excellent life span on a 4100 cool white tube. So, why pay extra for a product that can last for years.
