Customer Reviews from Amazon
Most Helpful Review
"They seem to work well and are at least as bright as the fluorescent tubes that they replaced (not all LED "equivalent" tubes are equivalent). I did a type B (ballast bypass) installation on a T12 fixture.However, SUSLUM says: "SUSLUM is not responsible for any issues arising from installation with a non-listed ballast. Such issues are not covered under the warranty." But the only ballasts that they list are 32 Watt T8 ballasts, so if you have a T12 fixture, type A ("Plug and Play") installation might not work and could cause the tubes to fail."
