LED, or light-emitting diode, light bulbs are an excellent choice for lighting because they use less energy and last longer than CFL bulbs but cost about the same. But how many watts do LED lights use? Actually, it depends on the brightness of the LED lights. Here we will know the watts which LED lights to use!

How Many Watts Do LED Lights Use?

Typically LED lights are brighter than CFL or Incandescent Light Bulbs. LED equivalent wattages to traditional light sources can only be imagined because they depend on the color temperature and quality of the bulbs being compared.

When comparing different light bulbs and lamps, it’s best to look at how many lumens each one puts out. This will give you a better idea of how they compare. Here we have listed the use of LED light watts compared to other Lights in the market.

LED Lights Watt Vs Incandescent Light Bulbs Watt

Incandescent light bulbs use the most energy to produce the same amount of light as LED light bulbs, which use only 10 percent of the energy of incandescent light bulbs.

LED Lights WattIncandescent Light Bulbs Watt
10 Watt100 Watt
7.5 Watt75 Watt
6 Watt60 Watt
5 Watt50 Watt
3 Watt30 Watt

LED Lights Watt Vs Halogen Light Bulbs Watt

Halogen light bulbs use less energy than traditional incandescent bulbs, but they still use a lot more than LEDs, which use about 85% less energy than halogen bulbs.

12 Watt100 Watt
11 Watt75 Watt
8 Watt60 Watt
6 Watt50 Watt
4 Watt30 Watt

LED Lights Watt Vs CFL light bulbs Watt

CFL light bulbs were the first natural energy-efficient alternative to incandescent and halogen bulbs. They use much less energy and last much longer. LED light bulbs take energy efficiency to a whole new level. They use about 40% less energy than CFL bulbs of the same brightness.

LED Lights Watt Vs Fluorescent Tube Lights Watt

LED tube lights use 40–50% less energy than fluorescent tube lights, similar to CFLs because they use the same technology.

  • Electricity costs will vary. The numbers above are not exact and were only used to give you an idea. Hawaii’s residential energy costs are 35.17 cents per KWh, while Washington’s are only 11.4 cents per kWh.
  • LEDs can cost different amounts per bulb. We took the average price of $5 for a 60-watt-equivalent LED bulb from stores that sell lights.
  • Estimates of how long a light bulb will last because it would take about six years of constant lighting to test. Some manufacturers say the new LED bulbs will last up to 25 years under regular household use, but this is not proven.
  • This chart doesn’t consider how often bulbs break or how much it costs to replace them. CFL bulbs and incandescent bulbs are more likely to break than LEDs, making them more expensive.
  • Most LEDs come with a guarantee of at least two years. Most broken LED bulbs will break within this time.

Final Words

You can use a calculator to get an idea of your LED light energy use. The calculator uses the average number of watts for an LED light bulb, 100 Watts. You can put in information about your LED Light Bulb to determine how it is used and how much it costs. Here is the calculator!
