Went to Home Depot (Canada) to get a replacement T8 bulb. Stumbled across T8 LED Direct Replacement bulbs, regular $29.95 marked clearance for $7.49. Bought all 10. They are Phillips, 1600 Lumen 4000K. I bought a complete LED fixture to replace one of my 4' Flourescent fixtures a while ago, and the difference in available light is fantastic, but it cost me $135 plus tax for the fixture. I figured for $7.49 how could I go wrong, and I was right. Marked difference in light presence in my shop. Still have a few T12 4' fixtures that have the old ballasts, so I cannot use the bulbs in them. Someday I'll hit the right sale and replace those as well.
