I picked up a $35 LED bulb that’s allegedly equivalent to a 75 W incandescent, replacing a 100 W equivalent compact fluorescent bulb that an X10 relay switch couldn’t turn off cleanly, for a torchiere floor lamp. ‘Nuff said about early CFL failures.
It has both upward and downward facing LED chips that light up the diffuser and ceiling in equal measure. Both strings are visible from the side due to the heavy molded plastic lens around the chips:
Some interesting bits from the package:
A 22.8 year lifespan at three hours per day works out to 24.983×103 hours. I wish I could have heard the arguments about whether they could claim a 23 year lifespan…
At the same duty cycle, the 5 year warranty covers 5.479×103 hours. Huh.
The URL at the bottom leads to some general info, but nothing you didn’t know already.
It works well enough, but at $35 it’s really a capital investment that I suspect will never actually pay for itself…
