Businesses using these bulbs routinely cut their electricity bills by significant margins. Savings are most pronounced in high-consumption spaces such as office complexes, warehouses, or factories. The more bulbs required, the more money LEDs save.
Many businesses, however, never consider how LED’s can reduce labor and maintenance costs, adding another money-saving advantage of switching to LED’s. What does one have to do with the other? Think about it. A burned-out bulb doesn’t just replace itself. Somebody has to do the replacing. Certainly not the janitor or new hire. It’s the maintenance person, who’s on a daily, eight-hour payroll. And that can add up to a tidy sum.
Now picture a towering high-rise or sprawling warehouse. All those bulbs in all that space, many of which will be inconveniently located on a high ceiling or in a hard-to-reach fixture. That means not only carrying and installing the new bulbs but climbing up and down ladders or using machinery that requires training. With all the jokes out there about how many people it takes to change a light bulb, we often forget that on a large scale it’s a lot bigger job than just screwing a bulb in. On a large scale, someone has to keep track of inventory on all the types of bulbs. Light outages can lead to accidents and keeping a large building lit becomes a labor-intensive and time-consuming. And time is, of course, money.
LEDs tremendously reduce such labor costs. That’s because they don’t require replacing nearly as often as conventional light bulbs. The average life cycle for one of these bulbs is about 50 kW (kilowatt) hours or 50,000 hours. On average, a conventional incandescent bulb lasts about 1,000 hours. That means an LED lasts 50 times longer than an incandescent. And as mentioned earlier, LEDs have amazing durability. As a result, you’ll change a conventional bulb 50 labor-consuming times before you change an LED even once!
The labor savings provided by LEDs depends on different variables. Distance maintenance person must travel to retrieve bulb, transportation method (foot or vehicle), height/accessibility of bulb fixture, and other factors all contribute to labor time.
HOW MUCH CAN LEDS SAVE?
As a simple example, let’s assume an average bulb-changing time of 15 minutes and a per hour labor cost of p60.00. Replacing one LED bulb will cost a modest p15.00 (for the one-quarter hour). But during the lifetime of that single LED, you will have changed the incandescent 50 times, which brings the total to p750 (50 x p15.00). That’s p15.00 for the LED vs. p750.00 for the incandescent!
But that’s only one bulb. Assume your place of business requires 200 bulbs. Total replacement cost for the LEDs would be p3,000.00 (200 x p15.00). For the equivalent amount of conventional bulbs, the total replacement cost would be a staggering p150,000 (200 x p750.00). Quite a gap! Which would you choose?
