Nice! What did you have to give for the bulbs? I have about $27/fixture (4 bulbs)So, after reading this thread one of my ballasts failed in a t8 fixture. It’s actually cheaper to do this led conversion than to replace a ballast.
Turns out that these led t8 bulbs actually make much less light output at 1800 Lumens than the t8 at like 2800 but since they are directional, the output is equivalent if not slightly brighter. Half the wattage and instant full power.
I converted 20 bulbs so I save 360 watts anytime they’re on. View attachment 273005
