For example, a 100 W incandescent bulb produces about 1,600 lumens, for an efficiency of 1,600/100 = 16 lumens per watt. A halogen bulb, on the other hand, consumes only 72 watts for the same amount of brightness, making its efficiency 1,600/72 = 22 lumens per watt. A CFL bulb ...
1600 lumens Incandescent: 100 watts Compact fluorescent: 23–30 watts LED: 16–20 watts It is evident from the comparison above that the LEDs require less power, thus they are more efficient in operation. A unit price for an LED light is still high compared to incandescent lights, but ove...

Nanometers measure the length of very small magnitudes, such as wavelengths. A joule, abbreviated as J, is a unit of energy in the metric system. The conversion between nanometers and joules is important in physics because scientists often need to calculate the energy of electromagnetic radiation...
