SunparkSL27T (short version) !!!Mfr has changed wiring and size from previous versions!!! electronic ballast for multiple CFL and Linear fluorescents

Different color wires than the original ballast., but it works just fine.

it worked well

Works good. replaced the one in our kitchen and it's working again now.

These saved the day at the job site, thanks.

Bought this by mistake because of confusing description. It is *not* a replacement for the old style SL27T, and does not have wiring instructions for "linear" bulbs (which I take to mean "straight.") Look closely at the schematic in the diagram in the picture, do NOT buy if you're trying to replace a SL27T with typical 4' straight bulbs. The description should at least have clearer schematics, as many do.

Replaced old ballast of same model. Wiring change was confusing with no explanation except poorly reproduced schematic. Was meant to allow ballast-compatible LED tubes to replace fluorescent tubes. But LED tubes did not work (tried 2 pairs) Ended up using two new fluorescent tubes. Could not return LED tubes to store because of no-return policy on light bulbs.

It works but with a delay in lighting the bulbs.

It fit my need thank you
