Incandescent light bulbs vs. LED
Did you know that your household energy bill is ten percent lighting costs? The fastest way to reduce your energy bill is by upgrading to LED efficient lighting. The initial cost of upgrading to LED is expensive, but LEDs can cut costs by nearly eighty percent, and LEDs will last twenty-five times longer. What are the best-LED light bulbs for home use?

The Led (light emitting diode) is today’s most efficient lighting technology. LEDs are durable, and longer life offers better light quality than comparable lighting. LED’s use 10 percent of the energy of an incandescent light bulb. LED’s come to full brightness without the need to warm up. The life of fluorescent lamps diminishes by turning them off and on. LED lights, however, are not affected by this action.The initial cost of upgrading to LEDs is higher than traditional lighting.
The one degradation for LED lighting is the dye and packaging materials reducing light output to some extent over time. Like incandescents and unlike fluorescents and CFL’s.
The LED market is going to grow to twenty-five billion by the year 2035. A compound annual growth rate (CAGR) of 25 percent. Indicating how consumers are reacting to the LED light efficiency of this technology.
LED’s are manufactured to be a direct replacement. LED packaging may show the lumens output, power consumption in watts, color temperature in kelvins or description (warm, white) operating range. And information showing consumers lumen output to the wattage of similar incandescent bulb lumen output.
Residential lighting especially Energy Star rated products use 75 percent less energy and last 25 times longer than incandescents. Your use of LEDs in your home will have the most significant impact on your energy savings.
Compared to incandescent halogens and compact fluorescent lamps (CFL’s) the light emitting diode (LED) has many benefits.
- 25-80 percent better efficiency energy consumption than a light bulb
- Lasting 3-5 times longer
LEDs have a wide variety of colors and lumen light levels. They are higher in costs compared to traditional lighting. They will, however, be more efficient and economical to operate and last longer over the life of the bulb. Benefiting consumer not having to replace them as often.
CFL bulbs vs. LED bulbs
The comparison table compares a 60 watt (W) traditional incandescent with energy efficient bulbs that provide similar light levels.
Comparisons between Traditional Incandescents, Halogen Incandescents, CFLs, and LEDs
|60W Traditional Incandescent||43W
|15W CFL||12W LED|
|60W Traditional||43W Halogen||60W Traditional||43W Halogen|
|Energy $ Saved||–||~25 percent||~75 percent||~65 percent||~75-80 percent||~72 percent|
|Annual Energy Cost*||$4.80||$3.50||$1.20||$1.00|
|Bulb Life||1000 hours||1000 to 3000 hours||10,000 hours||25,000 hours|
*Based on 2 hrs/day of usage, an electricity rate of 11 cents per kilowatt-hour, shown in U.S. dollars.
HOW LEDs ARE DIFFERENT
LED lighting is very different from other light sources such as incandescent bulbs and CFLs. Fundamental differences include the following:
- Light Source: LEDs are the size of a speck of pepper, and a mix of red, green, and blue LEDs is typically used to make white light.
- Direction: LEDs emit light in a particular direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and task lighting. With other types of lighting, the light must reflect in the desired direction, and more than half of the light may never leave the fixture.
- Heat: LEDs emit little heat. In comparison, incandescent bulbs release 90 percent of their energy as heat and CFLs release about 80 percent of their energy as heat.
The advantages of using LED lighting
Safer: LEDs are much cooler than incandescent lights
Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.
Longer lasting: LED’s last 25 times longer than traditional bulbs
Easier to install: You can connect many on the same circuit without fear of overloading the circuit.
Estimated cost* of buying and operating lights for ten holiday seasons
|Incandescent C-9 lights||$122.19|
|LED C-9 lights||$17.99|
*Assumes 50 C-9 bulbs and 200 mini-lights per tree, with electricity at $0.119 per kilowatt-hour (kWh) (AEO 2012 Residential Average). Prices of lights based on quoted prices for low volume purchases from major home improvement retailers. All costs have fallen at an annual rate of 5.6 percent. Lifespan assumed to be three seasons (1,500 hours) for non-LED light
LED light output of a single LED is less than a traditional incandescent light bulb or a CFL. In most applications, you will see multiple LED’s that make up the lamp. LED’s come to full brightness when turned on. No need for warm-up coming to full illumination as soon as you flip the switch. As you can see upgrading to LED lighting can be the easiest way for you to reduce costs to your energy needs. LEDs are safe, durable, and sustainable and offer you the best-LED light bulbs for home use.
