Is a 40 watt incandescent bulb the same brightness as a 40 watt led bulb?

NO Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.

How many watts does a 60 watt high efficiency bulb use?

Normally the watts is a measure of how many watts of electicity a bulb uses, so a 60 watt bulb uses 60 watts. The brightness is measured in lumens, so a 60-watt incandescent blub might produce 600 lumens while a high-efficiency fluorescent blub might produce 3000 lumens.
