5 Benefits of LED Fixtures and Bulbs
The residential lighting business slowly began to incorporate white LED around 2007. Since that time it has become a preferred lighting option. Here's why:
Saves You Money
Today’s LED bulbs can be 60-70 percent more energy efficient than conventional incandescent lights and cut energy use by up to 70 percent.
On average, the homeowner will save $75 per bulb on the lifetime operation of an Energy Star® LED bulb vs. a traditional incandescent. Multiply that by the number of bulbs in the home and the number of years the home is occupied and that can add up to a considerable savings.
LEDs are used in a wide range of applications because of their unique characteristics, which include compact size, ease of maintenance, resistance to breakage, and the ability to focus the light in a single direction instead of light spreading out in many directions.
- There is no filament that can be broken, reducing the chance of breakage before use.
- Unlike Compact Fluorescent Light bulbs (CFLs), LEDs will turn on to their stated light output immediately – no waiting for the bulb to reach full illumination.
LEDs contain no mercury (like CFLs) and have a much smaller environmental impact.
UV Free - UV emissions are said to be harmful to health after prolonged exposure.
Incandescent bulbs release 90 percent of their energy as infrared radiation making them hot to the touch. While CFLs release 80 percent of their energy, a high quality LED produces no infrared radiation keeping them typically cool to the touch. With little-wasted energy, LEDs ultimately save homeowners long-term energy costs.
Did You Know: LED stands for Light Emitting Diode.
LED vs. Standard
Compared to the Standard Incandescent Bulbs, LEDs:
- Are smaller in size, allowing for new looks and compact fixture designs.
- Consume less energy, resulting in lower utility costs.
- Are proven to be more durable and reliable.
- Have a life expectancy that is 15 times longer than an incandescent, leading to lower replacement costs.
- Are less expensive to the customer over the lifespan of the product, despite higher upfront costs.
Tip: Light can emit different tones and colors based on a couple variables. Learn more about color temperature here.
Learn about Lumens
Watts vs. Lumens
- Watts is the measure of energy required to light the product. The lower the wattage, the less energy consumed.
- Lumen/Light Output measures the light output. The higher the lumens, the more light that is emitted.
- Lumens per Watt/ Efficacy is the measure of efficiency. The higher the lumen per watts, the more efficient the product is.
Total Lumens vs. Delivered Lumens
- Total Lumens represents the total amount of light emitted from the LED module itself. This figure does not take into account any light losses from filtering light through the LED lens or luminaire cover lens, losses from the distribution of light from an internal reflector or luminaire positioning for example. In reality, it is only a theoretical number with no bearing on real performance.
- Delivered Lumens does represent real exit lumens that are projected from a lamp or luminaire. These are the actual working lumens projected toward the horizontal or vertical plane and account for any system losses that may exist within a fixture or lamp.
