From Kiwi :- The watt (play /?w?t/ WOT; symbol: W) is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736?1819). The unit, defined as one joule per second, measures the rate of energy conversion or transfer.
okay, so we have Joules per Second (J/s). And i suppose X seconds of 40W of Incandescent is not equal to X seconds of 40W of Halogen ?
Hurry up with the free beer :;

The Halogen lamps are roughly 100% more efficient - same illumination for half the consumed power.

Aw c'mon.The question was which of them produces more HEAT !, not which is more efficient !
In a closed system, obeying laws of conservation of energy, i.e. no heat losses, that would translate into exactly the same amount of HEAT.
Pah! It's awful what one has to go through just for a free beer nowadays !
