Has anyone ever stopped to notice that General Electric's 75 watt lightbulbs and (I think also) 100 watt bulbs are only rated for 750 hours of use?
These are the kinds normally sold in the big-name supermarkets and in corner groceries at pretty outrageous prices for a 4-pack.
Meanwhile, the off-brand Chinese bulbs (4 bulbs for a dollar) available from the dollar stores are usually claiming 2,000 to 5,000 hours of use.
I've noticed the off-brand bulbs are usually rated for 130 volts, while GE's are rated for 120. And I've also noticed that the Chinese bulbs do last significantly longer (filaments are also better supported)
What I'm wondering is if GE actually designs its 75watt+ bulbs around a rating of 110 and then marks them up with a 120 volt rating in order to:
1) make the bulb burn brighter
2) make them burn out faster so you have to buy more bulbs.
It's a CONSPIRACY, I tell ya!
