In 2022, the Biden-Harris administration proposed new legislation that would increase energy efficiency requirements for light bulbs from 45 lumens per watt to 120 lumens per watt, effectively banning CFLs, which produce up to 70 lumens per watt.Lots...
Light bulb bases are identified using a code similar to the code used for the bulb, so identifying the size of a light bulb is simple. The letters in a bulb code indicate its shape and special features such as reflector type. The numbers of the bulb indicate its base size, which is ba...

Per watt, LEDs output more lumens (or quantities of visible light) than regular incandescent bulbs. Light emitting diodes have a higher luminous efficacy (how efficiently electricity is converted to visible light) than incandescents – a 60-watt incandescent bulb can generate between 750-900 lumens...

The enhancements in the phosphor and the chip epitaxy have some role in extracting higher lumens per watt from the LED package. The luminous efficacy is also influenced by the temperature. When the operating temperature of the LED package increases, there is a drop in its efficacy. This drop ...
Relying on these wattage equivalencies can lead you to buy a bulb that ends up being far too dim or too bright for your needs, and this is where understanding lumens really comes in handy. With lumens listed on each and every bulb, you'll always have a concrete comparison of how bright...
