We’re sure you’ve heard that LED light fixtures are the greatest creation since sliced bread, but recognizing exactly how the efficiency of LEDs compares to traditional incandescent bulbs is beneficial as you consider your personal outdoor lighting design. This blog post is intended to help you understand the very substantial economic benefits of LED illumination compared with traditional incandescent lights. For a comparison of the design and function of GasGlow® LED versus incandescent candelabra base assemblies, please see our blog post titled, “GasGlow® LED vs. Incandescent Candelabra Base Assemblies
Incandescent lighting is the traditional form of electric lighting that was made practical by Thomas Edison over 130 years ago. LED lighting systems, on the other hand, were first produced in the 1960s and have become widely adopted just over the past decade.
The principal differences between an electric incandescent candelabra base and our GasGlow® LED
: An electric incandescent candelabra base
employing two 40-watt bulbs generates approximately the same light output as a dual GasGlow® LED assembly
. However, the light bulb fixture will consume approximately 80 watts of energy per hour, whereas the GasGlow® LED
will use only approximately 9 watts. If your lamp is in operation for 12 hours/day, the electric incandescent fixture will use near 350 kilowatts of energy per year while the GasGlow® LED
will use less than 40 kilowatts. At an energy cost of 10₵ per kilowatt-hour, the GasGlow® LED
costs almost $30/year less
than incandescent light bulbs – in just electric costs alone.
: Incandescent electric assemblies
use screw-in light bulbs that burn out and require regular replacement. GasGlow® LED assemblies
do not use light bulbs and require virtually no maintenance.
: While the typical lifespan for an electric light bulb is around 1,000 hours, LED fixtures can last for many years. Two independent testing laboratories estimated the lifespan for our GasGlow® LED assemblies to be well over 50,000 hours, or 15+ years if operated 12 hours/day.
The following table provides a summary of the remarkable economic benefits offered by GasGlow® LED illumination
compared with traditional incandescent electric bulbs:
American Gas Lamp Works is proud to offer GasGlow® LED
as an American-made solution to the green lighting challenges of the 21st
century. In fact, GasGlow® LED fixtures use so little energy that we recommend customers leave them on 24 hours/day to best mimic the look of gas mantle lamps.
