Traditional lighting is a consumable commodity which uses a lot of energy to generate a lot of light and burns out quickly. You spend a little on the lamp and a lot on the energy. Every year in your house you are likely to be spending around £30 on energy alone for every single light in the kitchen. In your hotel corridor you are likely to be spending around £50 a year on energy alone for every single light.
With LED lighting you have the option to get light that lasts. As the graph below illustrates there are plenty of prices and products available but how much light do you want and for how long ?
Basis for calculations:
- Lights on: 5,000 hours pa
- Electricity charge: 0.12p kWh as Energy Savings Trust assumption
- Relamping cost: £2.00 a unit
Product assumptions:
-
7W Budget LED: Cost price: >£20
- Light type: lamp
- Light output: > 200 Lumens IE 1/3rd of halogen
- Defined life (Unregulated) 30,000 hours
- Actual likely longevity of full light quality: 10-15,000 hours
-
7W Average LED: Cost price: >£20- 40
- Light type: lamp or luminaire
- Light output: >350 Lumens IE c.1/2th of halogen
- Defined life (Unregulated) 30,000 -50,000 hours
- Actual likely longevity of full light quality:20-30,000 hours
-
7W Premium LED: Cost price: >£45 +
- Light type: luminaire
- Light output: >500-600 Lumens = halogen
- Defined life (Unregulated) 50,000 – 80,000 hours
- Actual likely longevity of full light quality:50,000 – 80,000 hours

If you replace the halogen downlights in your hotel corridor with 10 x 200 Lumen LEDs you will have lost over 65% of the light you used to have in that space.
