Yep. When the math works with the guarantee that's in the fine-print, then I'll consider it. The CFL guarantees have worked ok for me...didn't have to send them back, just needed to call them with a few values from the receipt and the packaging or from the bulb. Seemed kind of silly to mess around like that for a $4.22 check, but it's the principle of the thing. Especially when the marketing was 7 years and it lasted less than 2.
Yeah, that's what I'm talking about. 2 years vs claimed 7. My LED lasted <1 year but was supposed to last 22. I'm very leary about these claims now. As far as I've seen, both CFL and LED don't last significantly longer than the incandescent but cost 5X as much. Sure they use less energy but at the higher cost and the BS "long" lasting they cost more. I hope the newer ones last longer but I'm pretty pessimistic about it.
