So what type of low energy bulb should you buy?
Both CFL light bulbs (low energy light bulbs) and LED light bulbs offer substantial energy savings. LED bulbs offer the greater saving overall using less energy and lasting longer at 60,000 hours.  CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon dioxide a year. If every family made the switch, we’d reduce carbon dioxide by billions!

Will just swapping light bulbs make a difference?
By swapping a normal bulb to an energy saving bulb you could cut energy wastage by three quarters and save money on your electricity bill. It might seem like a small change, but if every home changed just 3 light bulbs, enough energy would be saved to light the countries street lamps.

But don’t energy saving light bulbs use more energy when first turned on, therefore wasting more energy if switching lights on and off?
Carbon Footprint carried out an in-house investigation and found that if anything low energy bulbs used slightly less energy when first switched on, gradually building up to a continual wattage (which only took a couple of seconds).

CFL Low energy light bulbs contain mercury, is that safe?
Low energy bulbs do contain a small amount of mercury which is not at all dangerous when contained within the bulb. The bulbs should be disposed of responsibly and can either be collected in your normal household waste bin or can be recycled at your local council’s Household Waste and Recycling Centre or at collection points provided by some light bulb retailers.
