If both are designed to run on the same source voltage, then they're interchangeable,
but the 300-w unit will produce less light than the 500-w unit.
Note:
If the mechanical designs are identical, i.e. they can both mount in the same receptacle,
then they're most likely designed to run on the same source voltage. Lamps designed for
different voltages are usually built with different mechanical designs so that they can't
fit into the same socket. It's assumed that most users are too careless to check their
bulbs, and that they'll routinely install anything into any place it fits.
A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.
300-500 = -200
300 + 500 = 800
Wikpedia says that halogen lamps produce about 19-20 lumens/watt. If you have a 500W lamp then you get 9500-10000 lumens.
300 over 500 is 60%
60% of 500 is 300.$300
3/5 of 500 is 300, since 500 / 5=100 x 3= 300 so 300.
300/500 = 3/5
The GCF is 100.
The LCM for 500, 300 is: 1500
