How many w of regular CFLs is a 5w LED bulb equivalent to, and how many watts of incandescent light is it equivalent to?

5w LED bulb light is equivalent to 15w ordinary energy-saving lamps, equivalent to 60w traditional incandescent lamps. More power saving, more environmental protection.

The replacement of LED lamps with incandescent lamps is not simply measured in terms of W number. For example, the same 10W LED lights, some are 800 lumens, some are more than 900 lumens. This is to understand the concept of "luminous efficacy", that is, how many lumens per W of light emitted.

The luminous flux of a 40W incandescent lamp is 400 lumens, so the luminous efficacy of an LED lamp is 80 lumens per watt, so the LED should be 400/80=5W.

LED use of cold light source, glare, no radiation, the use of hazardous substances do not produce.LED low voltage, DC drive mode, ultra-low power consumption (single tube 0.03 ~ 0.06W), electro-optical power conversion is close to 100%, in the same lighting effect than the conventional LED's environmental benefits better, no ultraviolet and infrared in the spectrum, and the waste can be recycled, no pollution, does not contain mercury, can be safe to touch, belong to the typical green lighting light source.

LED for solid cold light source, epoxy resin package, anti-vibration, the lamp body also has no loose parts, there is no filament luminous easy to burn, heat deposition, light attenuation and other shortcomings, the service life of up to 60,000 ~ 100,000 hours, is the life of the traditional light source of more than 10 times. LED performance is stable, can be in the environment of the normal operation of the -30 ~ +50 ° C environment.
