Loony Question for Today...

Which produces more HEAT, a 40W Incandescent, or a 40W Halogen bulb?

...Jim Thompson

Heat is Energy , measurable in Watts,

The W is a unit of power (energy per unit time), not energy.

No free beer for you.

From Kiwi :-
The watt (play /ˈwɒt/ 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 :;
