Halogen lightbulbs ?

Hi i think i know the answer but i would like it confirmed really that a halogen lightbulb in a small reading lamp uses more electricity that an ordinary bulb. Is that correct ? Thanks

It depends on the wattage you are comparing with a normal bulb.

It will certainly consume more power than an energy saving (compact-fluorescent) bulb.

Hi thanks for replying. Im using a 240 volt/129watt 78mm linear halogen bulb as my bedside light. I need a bright light so it would be a 100 watt ordinary bulb or one of similar brightness in the energy saving ones. I notice this one seems to give out heat too is that what they do ?

You have a tungsten filament lamp that consumes approx. 129w. That's more than most light bulbs. These lamps are never very efficient and I recall reading somewhere that 90% of this energy consumption is wasted as heat.

You may want to consider capsule type halogen lamps that are more energy efficient.

Hi I ve looked at a new pack of these bulbs and they re classed as a C. This is from A to G. Is A the most or worst ive forgotten lol. Also mentions 2250 lumens whatever they are. I wouldn t say the 90% energy consumption is wasted as heat as at this time of year it seems to make the bedroom warm as we dont have the heating on much ( thats another story ). I ll have to see what capsule type halogen lamps look like.:). Thanks

A is the most energy efficient, G the worst.

Energy saving compact fluorescent lamps around 20W are equivalent (in light output - lumens) to a standard 100W lamps.

However, the compact fluorescent lamps can have quite a cold colour and won't produce much heat either!

You may want to consider an LED lamp. They are now available in warmer colours (like normal lamps) and the light angle can be narrower which will be good for reading. LED lamps are typically a few watts but produce a very bright light.
