Switching to LED tubes provides easy-to-measure cost savings. When you book an assessment our technicians will use a watt/voltage meter to compare, in real time, the electricity used by your fluorescent tubes, against that used by our LED tubes. They will also use a light meter to prove there is no loss of brightness when you make the switch.
The electricity used by an electrical device is measured in watts. A 40 watt fluorescent tube uses 40 watts per hour and a 20 watt LED tube uses 20 watts per hour.
A comparison of the electricity useage of 200 fluorescent tubes and 200 Led Tubes operating 15 hours a day 6 days a week is as follows
LED V Fluorescent - Kilowatts Used
Electricity costs are increasing but, today, electricity costs about 22c per kilowatt and the costs and savings are set out below.
This cost calculation has been kept simple. In reality the electricity usage of a fluorescent tube is higher than that illustrated above because fluoresent tubes required a ballast to run (a ballast is not required for the LED tube). The ballast uses an additional 3 watts (approx) of electricity.
