The short answer: total operational cost over an LED lamp’s lifespan is significantly lower than its fluorescent counterpart; see the following illustration for a typical comparison between conventional, fluorescent & LED lighting:


Halogen Fluorescent LED
Approximate cost per bulb £1 £1 £5 or less
Average lifespan 1,200 hours 8,000 hours 25,000 hours
Watts used 60W 15W 10W
No. of bulbs needed for 25,000 hours of use 21 3 1
Total purchase price of bulbs over 20 years £21 £3 £5
Total cost of electricity used (25,000 hours at £0.15 per kWh) £180 £42 £30
Total operational cost over 20 years £225 £56 £38

How Much Could Your Business Save?

The above illustration shows the  savings from just one bulb.

Consider the total number of lights in your premises — some fixtures use 3 or even 4 lamps/tubes, for example. If you replaced 20 such fittings with LED light lamps throughout your establishment, you could save several thousand pounds over their 20-year lifespan (and that’s assuming utility rates don’t rise).
