Personaly I'm using architect lamps, with this reference of "fluocompact" daylight bulbs :
OSRAM DULUXSTAR Mini Twist
Cool Daylight 6500K
I'm using the 22watt, I believe. It stays relatively cold (so you can stay hours working behind it without frying your brain), and the quality of the lamp is great : fast, stable, and perfect daylight. It's also very durable.
I don't know about led lamps, it should be even better (more durable, and cold) than "fluocompact" bulbs, as long as you find the correct light temperature. 6500K is daylight, perfect for figures painting.
Warmer light will make your reds look orange, and your whites look yellow.
Cooler light will make your white look blue, red will appear purple.
