What's the new light bulb rule? In April 2022, a new regulation was passed by the Department of Energy under President Joe Biden's administration. The rule requires light bulbs to emit a minimum of 45 lumens per watt. Lumens refer to a specific measurement of brightness. That means there...

In terms of color changing, CFLs and incandescent bulbs need filters in order to emit colored light. That limits the user to one king of color per bulb. However, LEDs are designed to generate an entire spectrum of visible light colors. 5. Dimmability When it comes to dimmability, different ...
In December 2022, the Department of Energy proposed a rule that would more than double the current minimum light bulb efficiency level, to over 120 lumens per watt for the most common bulbs. That would go into effect by the end of 2024 andeffectively ban CFL bulbs. ...
so when you replace that 100 W incandescent bulb, put in a 25 W CFL, and you’ll get about the same amount of light – about 1700 lumens. Those numbers yield light bulb efficiency ratings (called efficacy) of 17 lumens per watt for incandescent bulbs and 68 lumens per watt for CFL ...
LEDs are one of the most energy efficient sources of lighting. They draw a very small amount of power and they have a high light output (up to 135 lumens per watt). Unlike other lighting sources (CFL and incandescent lights), LED lights also produce very little heat, and thus nearly all...

(with the remaining energy being converted into heat). The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such ...
Because of recent advances in optics, LEDs have a quality of light superior to all other types of lighting—and they deliver it more efficiently. For example, Lighting Science Group's Definity LED delivers 112 lumens per watt compared to a CFL's 50 to 70 lumens per watt. Improvements in...
