If you manage a warehouse, manufacturing plant, or commercial workshop, lighting is much more than just a routine administrative expense. It is one of the largest and longest-running operating costs for your facility.
Many facility managers focus solely on the initial purchase price of the fixtures when replacing older metal halide (MH) or outdated fluorescent fixtures. However, the factor that truly determines your bottom line over the next 5 to 10 years is luminous efficacy. Luminous efficacy is the efficiency with which industrial lighting converts electrical energy into light.
This guide will explain how the brightness of UFO LED high bay lights affects your electricity bill, how to calculate total operating costs, and why upgrading to Demilare industrial led high bay lighting is a good investment.
What is luminous efficacy? Why is this important for industrial and mining lights?
Luminous efficacy is measured in lumens per watt (lm/W). It's like the "miles per gallon" of an LED fixture:
-
The traditional metal halide lamps are 400-watt systems. After considering the losses from the ballast and the light decay, the actual brightness is only about 50–65 lm/W.
-
Standard-quality LED industrial and mining lights: The light output is around 110–130 lm/W.
-
Demilare high-efficiency LED industrial and mining lights: It has a high level of brightness, with a score of 140–150+ lm/W.
The Real Numbers Show the Difference in Cost:
To achieve a brightness of 24,000 lumens (the standard lighting requirement for 15–20-foot-high ceilings):
-
An older metal halide system uses 458 watts of power (including the ballast).
-
Standard LED fixtures use 200 watts of electricity.
-
Demilare high-efficiency LED industrial and mining lights are just as bright as other lights but use only 150 watts of electricity.
How to Calculate Annual Operating Costs Traditional Lighting vs. Demilare
Let's look at a normal 10,000-square-foot (about 930 square meters) commercial warehouse. This warehouse has 20 industrial lights that are on for 12 hours a day (4,380 hours per year). The average U.S. commercial electricity rate is $0.16 per kilowatt-hour (kWh). Here's the calculation:
Demilare can save you money on electricity every year.
-
Compared to traditional metal halide lamps: You can save $4,317.12 every year (a 67% reduction in electricity costs).
-
Compared to standard 200W LEDs: You can save an extra $700.80 per year thanks to higher lm/W luminous efficacy.
Real ROI Breakdown: Get your money back in less than a year.
When calculating your return on investment ( ROI ), you need to consider three main things: the initial equipment cost, savings on electricity bills, and reduced maintenance costs.
A. You won't have to spend much money to get started.
Demilare LED industrial and mining lights are much cheaper than what traditional commercial distributors charge. Those distributors charge as much as $180–$250 per light. Demilare sells its lights directly to contractors and directly to factories. The starting prices for popular 150 W – 200 W models range from just $59.90 to $89.90.
B. You don't have to pay to maintain or replace it.
Metal halide bulbs burn out after 10,000–15,000 hours of use. This means that you will need to rent an aerial work platform (at a daily rate of $200–$400) and hire an electrician to replace the bulbs. Demilare industrial and mining lights are made to last. They have a strong aluminum heat sink with cooling fins. They can be used for more than 50,000 hours.
Here's an example of how this can help your business: Upgrading 20 Old Warehouse Lights to Demilare
-
Initial investment (20 Demilare 150 W LED industrial lights @ ~$79.90): $1,598.00
-
Shipping: $0.00 (Demilare offers free shipping on commercial orders)
-
Installation labor costs: The total cost of the project was $2,398.00.
-
The total amount invested was $800.00.
Financial Returns:
First-Year Electricity Savings: You will save $4,317.12 on maintenance costs in the first year. +$600.00 (This will save you money on replacing bulbs and ballasts.)
Total First-Year Net Profit:
Demilare industrial lights will pay for themselves in less than six months. After that, every penny saved each month directly increases your factory's net profit.
Features to Look for When Selecting High-Efficiency UFO Industrial and Mining Lights
To make sure you get the most value from your investment over the next 5 to 10 years, look for the following key technical specifications when selecting lighting fixtures:
-
It supports 0–10 V dimming and sensor expansion ports. You can easily connect it to microwave or infrared motion sensors or light-sensing controls. This will reduce energy consumption by 30–50% during off-peak hours.
-
It's great at managing heat. A strong aluminum case protects LED chips from getting damaged by heat that builds up in high ceilings.
-
Optical Distribution and Glare-Free Design: The light is spread out over a wide area, so there's enough light in the aisles and workstations, but not too much in the way for forklift operators.
-
The product has a warranty and certifications for commercial use. It is tested to make sure it is strong and durable. It can resist dust and water, and it comes with a 3–5-year warranty.
