Lamps heat output

[howy1]

My other half wanted a couple of her lamps to look brighter , they have 60w candle lamps as stated as the max to be used on these lamps.
On investigation i found these new effecient lamps that give out 100w of light but they are classed as 18w , my question is can i put these in the lamps rated at 60 w as i dont understand how this correlates to me i only have 18w to contend with so should not cause any damage or is it the fact of the 100 w giving out to much heat , all help apprieciated .

Lamp output isn't measured in Watts - that's the power consumed (and dissipated) by the lamp.

So an 18W lamp will consume and dissipate 18W - the manufacturer's claim is that the light output is equivalent to a 100W GLS lamp.

The bottom line is that you shouldn't have a problem replacing a 60W lamp with a low energy 18W lamp.

Thanks goldberg , you have put my mind at ease .

Approximately 95% of the power consumed by an incandescent light bulb is emitted as heat, rather than as visible light.
An incandescent light bulb, with this ~5% efficiency, is about one quarter as efficient as a fluorescent lamp (about 20% efficiency), and produces about six times as much heat with the same amounts of light from both sources.

Incandescent lamps can usually be replaced by self-ballasted compact fluorescent light bulbs, which fit directly into standard sockets (but contain mercury, and thus should not be disposed of in a regular rubbish bin). This lets a 100 W incandescent lamp be replaced by a 23-watt fluorescent bulb, while still producing the same amount of light.

do not rely on manufacturers claims of bulbs being 5 or 5.5 times the light output you will just be dissapointed

simply multiply the wattage input off a low energy bulb by 4 so a 17w bulb would = 68w
and as said above a 23w is as near as dam it 100w

Interesting ... are the incandescent lamps being done away with ?
as i take it they where the ones recently removed from the shelves , just curious

Yes - you can no longer buy the type of incandescent lamp which can light a whole room with 100W.

But you can still buy the type of incandescent lamp which will not light a whole room with 500W.

Go figure.
