Yeah there are some good ones out there - just don't buy them at Home Depot.
The H/D ones buzz & flicker like a bastard.
All my Lightwiz ones have been great. Had a few early failures, but some are still blazing away after 5 years. At a buck a bulb, I couldn't pass that deal up - that's why I have my house full of them. Most of them get to full brightness in a few seconds, even when the house is in the upper 50's before I light up. Was some offer the power company had - if you lived in MA or RI, you got these bulbs for next to nothing. I tried them all: 15W, 20W, 25W, & 30W. The 30's are real bright, the 25's I thought were pointless because it's so close to the 30 & the 20 that you might as well go with the 20 - they thought the same as they've been discontinued, the 20 is ok, & the 15 is tiny - fits in any fixture & puts out more light than I expected. Great for hallways.
Everyone knows I couldn't give a rats ass about eco BS, but they work & they were cheap.
Plus, that's more power the generator has for everything else I've wired up to my transfer switch.
