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:
|Approximate cost per bulb||£1||£1||£5 or less|
|Average lifespan||1,200 hours||8,000 hours||25,000 hours|
|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).
