The technology uses 75-80% less energy than traditional incandescent bulbs. But the average lifetime is expected to be between 30, 000 and 50, 000 hours.
The difference in light color is easy to see.Warm yellow light, similar to an incandescent lamp, has a color temperature of about 2700K.(K is short for Kelvin, used for temperature, which measures the depth of light.)
Most Energy Star qualified bulbs are in the 2700K to 3000K range.3500K to 4100K bulbs emit whiter light, while those 5000K to 6500K emit blue-white light.
The energy consumption
The watt of a bulb indicates how much energy the bulb uses, but the labels of energy-efficient bulbs like LEDs list “watts equivalent.”Watt equivalent refers to the number of watts of equivalent brightness
in a light bulb compared to an incandescent bulb.As a result, an equivalent 60-watt LED bulb could consume only 10 watts of energy, more energy than a 60-watt incandescent bulb.This saves energy and money.
The bigger the lumens, the brighter the bulb, but many of us still rely on watts.For bulbs used in general lamps and ceiling lamps, called Type A, 800 lumens provide the brightness of
A 60-watt incandescent lamp;A 1100-lumen bulb replaced a 75-watt bulb;And 1,600 lumens is as bright as a 100-watt bulb.
Unlike other bulbs, LEDs don’t usually burn out.It’s just that over time, the light fades until it’s reduced by 30% and is considered useful.It can last for years, which is useful in your life.
All LED bulbs are mercury-free.CFL bulbs do contain mercury.Although the numbers are small and falling dramatically, CFLs should be recycled to prevent mercury from being released into
the environment when light bulbs break in landfills or landfills.If a CFL breaks at home, follow the Environmental Protection Department’s cleanup tips and requirements.
