How Many Engineers Does It Takes to Change a Lightbulb?

The question is silly, yes, but it could help determine if your facility spends too many labor hours on an asset that doesn’t need such attention, perenially saving you costs.

Lighting plays a crucial rule in any organization. According to the Energy Information Administration (EIA), the percentage of electricity usage due to lighting rose from 38% of total electricity draw in 1979 to 55% in 2003, more than that for space heating, cooling, ventilation, office equipment, and computers combined.

Some facility owners take for granted that LED lighting saves cost over fluorescents or incandescent lighting for their organizations. The question then becomes: what other benefits are there and how much could you save in labor costs by switching to LEDs?
LED lighting can reduce electric costs in your facility by 20% to 50% or more depending on which current light sources are being replaced.
The life of a LED replacement lamp or module in dedicated fixtures is much longer than incandescent, halogen, or T12 or T8 fluorescent tubes. Therefore, they don’t require replacing as often as conventional light bulbs.

The average lifespan of one LED bulb is about 50,000 hours where a conventional incandescent bulb lasts about 1,000 hours. So, you will change a conventional bulb 50-labor consuming times before you change an LED once.

There are a few variables that can affect labor savings when using LEDs. Facility managers should consider the distance maintenance personnel must travel to retrieve the bulb, transportation method, height/accessibility of the bulb, and other factors contributing to labor hours. Assuming an average bulb-changing time of 15 minutes, an average labor cost of $12/hour, replacing one bulb will cost- $3.00
But, during the lifetime of a single LED, you will have changed the incandescent bulb in the same fixture 50 times which brings the total labor changing cost to $3.00 for 1 LED vs. $150 for incandescents. And this is the cost to replace just 1 bulb. Assume your facility uses 200 bulbs, total replacement labor cost for the LEDs would be $600 vs $30,000 (200 x $150) for conventional bulbs!

Facilities can also save on ballast installation for fluorescent tubes; there is a labor cost associated with the installation of replacement ballasts which is avoided when upgrading to LEDs. Ballasts for fluorescent bulbs adds additional electricity use, too.

Maintenance expenses in the lighting world manifest themselves in three primary ways:
1. Cost of replacement lamps and fixtures
2. Cost of labor to replace said lamps or damaged fixtures
3. Warranty protection and duration
Therefore, in many situations, the substantial maintenance savings can nearly double overall project savings. LED is smart business when it comes to return on investment.

LEDs, like any other asset, are also best paired with an Enterprise Asset Management (EAM) software in a Computerized Maintenance Management System (CMMS). This allows technicians to keep records of all maintenance done on the bulbs to show proper cost savings and retrieve asset history, demonstrating that LEDs are the smart move.
Hospitality Equipped With LEDs

The hospitality industry is just one of many industries/businesses that could save on labor and maintenance cost by switching to LEDs. According to Lumenistics.com, “a hotel in Las Vegas reportedly replaced inefficient metal halide lights on the building’s facade with LED lighting; this move saved the facility about $41,000/annually.”

In the same article, there was a casino in Wisconsin that was expected to save “more than $221,000 in electric costs the first year the building’s new LED lights are in use, and $120,000 in maintenance costs over the next six years.”

Switching to LED bulbs give facilities more time to focus on other labor costs, maintenance situations, asset management, and less time focusing on an asset that can basically take care of itself and save you money.
Wouldn’t you want more options like that for your facility?

Mintek is a turn-key solutions developer for the telecommunications, lodging, and public utilities industries. Mintek’s EAM/CMMS software, Transcendent, provides access to customer, employee, and asset information beyond the traditional office. We allow facility managers to “run their business from their phone.” Our premise is that our technology must provide a rapid verifiable return on the investment.
