The running cost in electricity (£) and the power consumption (kWh) of
constantly running 50 bulbs.
We have designed these energy meters to represent the cost savings you could make on your electricity bill by switching to LED. The meters on the left represent a house with 50 halogen bulbs and the meters on the right, a house with 50 LED bulbs. The consumption is running as if all lights were constantly switched on. It’s exaggerated but it proves the contrast!
The cost and energy consumption has been running for:

Traditional light bulbs, halogen or incandescent may be 30, 50 or 100 Watts depending on the power they draw. The higher the Wattage, the brighter the light but the way these bulbs work is hugely inefficient. An electrical current is transmitted through a tungsten filament which heats it up red hot and the heat is reflected as light. Incandescent bulbs use 90% of the energy they consume in producing this heat – with less than 5% of the energy emitted as light.
Alternatively, LED light bulbs emit light by moving electrons through a semiconductor. This process wastes almost no energy in heat for the production of light. Therefore, LED bulbs can draw much less wattage to emit the same brightness as incandescents. Check out our guide on Watts vs Lumens for more info.
As a result, the power consumption and cost of running LED’s is much, much lower.
