Re: Light source lumens

LED annual running cost £1.71
These use almost 90% less energy than a traditional incandescent, making them the most energy-efficient type of lighting. LEDs are usually more expensive to buy, but should last up to 25 years. In the long term they are the cheapest option. An LED could save you more than £180 in energy use over its lifetime, compared with an old-style incandescent bulb.
