OK so another phase of the conversion to LED is complete at my house. Feit 800 lumen 9 watt 5000K units. Nice and bright, but flickery on generator power with bad cycles. They work great and are silent on modified sine wave inverter electricity but take a full second or two to light on inverter power, but light "instantly" at full brightness when it does happen. It's a little weird flipping the switch and having nothing happen for the first seconds, even preheat and rapid start fluorescents usually flicker or flash before that.
4 of the LEDs in two Y-adapters in clip lights in a room that will be lit with F96T12 slimlines once I get a case of lamps are very bright, you'd be surprised! Makes me almost think twice about the slimlines but the latter has the "cool" factor the LEDs just don't. I like having the "interesting" lighting like slimlines (the F96T12 slimline would probably be my favorite fluorescent lamp if I had to pick just one), vintage HPF 2XF40/RS with vintage lamps (my lights don't get used all that much, so I'm fine with having vintage lamps in use, (most of the F40T12 lamps in use presently are F40CWs, which haven't been made in 20 years LOL), or smaller preheat lamps. Eventually sone of the cheap stoplights and wraparounds with "residential" ballasts will probably get replaced with either more slimlines (I have extra, older, magnetically-ballasted fixtures) or F96T12/HO turrets I'm getting.
Another crazy idea I had: Replacing three "mushroom" type incandescent fixtures and a "breast" incandescent fixture with F96/HO turrets or slimlines. 800 lumen 9w LEDs replaced with 2X110w...LOL
