That's a weenie answer.

Simplistic questions deserve simplistic answers. You forgot to supply
any context, such was what you were trying to accomplish. Are you
concerned about temperature rise in some sort of package? Do you have
any efficiency or total power consumption compliance specifications?
Are you experiencing problems with one or the other technology?
Inquiring minds want to know.

I suppose you'd say I should use CFL's ?:-)

Nope. LED lighting would be too easy. For your unspecified
application, methinks burning torch, propane, kerosene wick, or
Coleman white gas illumination might be equally appropriate. Why
loose efficiency converting fossil fuels to electricity and then to
mostly heat in your lamps, when you can produce the light directly?
Think of all the possible applications for MEMS miniature propane
illuminators.
