TO CALCULATE YOUR ROI, USE THE TEMPLATE BELOW REPLACING ITEMS IN RED WITH RELEVANT DATA. (please call our sales team if you would like assistance)
1. CALCULATIONS: (Multiple the quantity of existing lights by their wattage and also the quantity of an equivalent LED product by the wattage)
20 X 35W existing Halogen/Incandescent Downlighters = 700W
20 x 4W new LED Downlighters = 80W
12.5p per kWh (this unit cost can be found on your electricity bill)
Lights on 7 hours a day, 7 days a week = 49 hrs per week
2. HALOGEN/INCANDESCENT (using the information calculated in 1 above)
49 hrs x 700W = 34.3 kWh pw (1 KwH = 1000W)
34.3 kWh x 12.5p per kWh = £4.29 pw
£4.29 x 52 weeks = £223.08 per year
3. LED (using the information calculated in 1 above)
49HRS X 80W = 3.9 kWh pw
3.9 kWh x 12.5p per kWh = £0.49 pw
£0.49 x 52 weeks = £25.48 per year
BY USING LED ILLUMINATIONS PRODUCTS (results calculated by taking 4 from 3 above)
ANNUAL SAVING ON ELECTRICITY = £197.60 PER ANNUM
LED LIFETIME 30,000 HRS = 10 YEARS
