Would the above be bright - in normal wattage would that just be 120watts or is it brighter since it is halogen. Thanks for any answers.

no it doesnt work like that.they are bright but it will be 40 watts spread around the room because theres 3 bulbs
It is 3 x 40 watts so 120 watt total.

not the brightest eh
For a given wattage, halogen bulbs are brighter than incandescents. They also last longer than incandescents. Tungsten incandescent light bulbs produce about 12.5-17.5 lumens per watt. A halogen bulb gives around 16-24 lumens per watt. That's around 30% brighter, so your 3x40w (120w) halogens would be like 160w worth of tungstens

sorry eddie thats was for Connemmara the questionaire
thumper, why would the light from 3 bulbs spread around the room any differently from the light from one bulb?
Like Heathfield said in his excellent answer ...

... they will use 120w of electricity, but will be about 25% to 30% brighter than conventional bulbs using the same 120w.

[ more of the power is turned into light and less into heat ]
It's far easier to think in lumens, rather than in watts, when comparing different types of bulbs.

Traditional incandescent bulbs have roughly the following light outputs:
40W > 450 lm
60W > 800 lm
100W > 1600 lm
150W > 2600 lm

Once you know those figures you can look at the packaging of any type of bulb and see how the light output compares. So, for example, these 40W G9 halogen lamps are rated at 410 lm, meaning that they produce slightly LESS visible light than traditional 40W bulbs:

All bulbs should now have their light output, in lumens, on their packaging, so you can easily compare different types.

I may only be allowed stated bulbs into this light. Thanks for all your answers. I do like a bright light.
