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).
