GU10 35w Spot (Aluminium)

Halogen spot bulbs produce a bright warm light. They are fully compatible with dimmer switches.

This is an aluminium reflector lamp that is designed to reflect the heat forwards away from the light fitting. Make sure that you choose the right sort of lamp for your fitting. Dichroic lamps reflect the heat backwards in the opposite direction to the light. See the related products tab for more options.

These bulbs are in no way low energy. At 35 watts each they use a lot of power, so you should only really use them if you have to. You should also consider the low energy alternatives - see the related products tab for more options.

There is a low energy 7w bulb that is exactly the same save as this 50w one, and an 11w version that is slightly longer. The only three reasons that we know of not to use the low energy versions are:

1. You need to be able to dim the lights using a dimmer switch

2. The slightly reduces light output from the 7w lamp is not brought enough and the slightly larger 11w version will not physically fit in your light fitting.

3. You happen to be able to produce all your own electricity from green energy sources (solar, wind etc) and don't mind using more than you need to

It's true the the low energy alternative lamps are more expensive to buy, but when you consider that they have a life of 8,000 hours (compared with 2000 hours for this halogen lamp) and will use up to 80% less electricity, this more than justifies the extra up-front cost.
