If graphene responds to heat even better than tungsten, doesn't that imply that you could use it to make longer-lasting, more efficient, incandescent light bulbs?

Anyone know what the color spectrum is like?

It's really bright at one end, but radically tapers off from there...

They already know how to make incandescent light bulbs that last longer than most of these crappy "CFL" bulbs you see these days.

Take a lightbulb made for the European market, and wire it up here (you might need different fixtures, I'm not sure if they'll screw into standard american sockets), and it will last for freaking years. Why? Because they were engineered to handle 220V rather than 120v current.

Incandescent bulbs fail as soon as they do here because they are engineered to do so, to keep you buying replacements. A ten-tear light bulb is of no use whatsoever to the folks who make them.
