Item not the same as pictured

The specs were correct however it was not the same item that was pictured. The wiring was different and not compatible with the light fixture that I had.

Perfect replacement.

Worked great. Going to buy another one for a separate fixture.

Replaced the ballasts in two 48" shop lights about 1 week apart. The first one had a Keystone ballast which I which I replaced with the same type, very easy to do and it worked great. The second shop light had a Sunpark ballast which I replaced with another Keystone ballast which I ordered, the wiring was different so I wired it up just like the first lamp with the Keystone ballast the previous week and it worked great. Leanlight ordering was just as requested and my orders were received early. Thanks
