LED Emergency Lighting vs Traditional Emergency Lighting
It used to be the case that LED emergency lighting was more always expensive upfront that its traditional equivalent, putting some customers off from investing in their longer-term savings. This is no longer the case, with the price difference typically being much smaller and, in many cases, even less for LED than traditional. This makes LED emergency lighting a natural choice.
For example, if you were to buy a system of 100 Orbik Eden LED bulkhead lights at £11.39 per unit you'd have an initial outlay of £1,139.00 compared to £1,599.00 for the equivalent Eden with traditional fluorescent bulbs. Even at first glance the LED lighting will cost you £460 less than the traditional lighting. A little more information confirms why LED emergency lighting is the right choice.
These LED lights have a wattage of only 5W compared to 21W for a standard bulb. Added up over the year (12hrs per day for a switchable maintained unit that is switched off at night) your LED lights would use 2190 KWH as opposed to 9198 KWH for the standard lighting. If we base the cost of the electricity at £0.125 per KWH your LED lights would save £836 per year in electricity.
LED diodes also benefit from longer lifespans compared to standard bulbs with an average of 50,000 hours compared to 30,000 hours for a standard T5 fluorescent bulb. If you factor 1 replacement bulb per light into your equations (around £1.99 per bulb), the standard lighting would cost you an additional £199.00 over their lifetime.
Your saving per week with LED lights would be £16.07 so, putting aside the fact that the initial outlay for LED lights is already cheaper, the continued savings mean you would have paid for them completely after 1 year and 19 weeks. These monetary savings start from day one and continue every day, week, month and year. The chart below shows the accumulative savings you could enjoy with LED lighting.
Other benefits that LED lighting has over traditional fluorescent lighting:
- Flicker free – while not usually visible to the human eye, fluorescent bulbs flicker enough to cause headaches. LEDs do not flicker at all.
- Mercury free – Unlike fluorescent lights, LEDs do not contain mercury, making them more environmentally friendly.
- Directional lighting – A fluorescent bulb casts light in all directions, much of which will be wasted. LED lighting is more directional so can benefit from lower lumen output for the same result.
So as you can see, there is much more to be saved when purchasing LED emergency lights than simply the upfront savings. With the right choice you can save from the off and continue to do so for years ahead.
