I bought a 48 inch t8 light fixture from lowes and also bought a 48 inch reptisun 5.0 t8 light bulb for it. I put reptisun light in fixture and wouldnt work,installed another regular bulb in and it turn on. Anyone else have a regular t8 light fixture running a t8 light bulb? Dont know if the light won't work for fixture or if the bulb is broken inside
