How many lumens does a CFL produce?
On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. Some of the most energy to light efficient LED bulbs are now reaching over 120 lumens in Energy Star tests.
What does 20 lumens mean?
A lumen measures the amount of light that comes from a bulb. It refers to a light bulb’s brightness, intensity of light and visible light emitted. A standard 40-watt (40W) bulb is equal to 400+ lumens. Typically, the higher the wattage, the higher the lumens, and the more light output.
What is 25w LED equivalent to?
Compare wattage
Traditional bulb1 | Halogen2 | LED |

Is LED brighter than CFL?
LED VS CFL Brightness Are LED lights brighter than or equal to Compact Fluorescent (CFL) bulbs? The trick is to understand the technology. In short, LED and CFL as technologies do not have a difference in brightness intrinsically. Brightness is determined by lumens.
How bright is a CFL bulb?
Lumens indicate the brightness, while watts indicate energy used to power the light bulb. For example, a standard 60-watt light bulb produces around 800 lumens of light. In comparison, a CFL light bulb that also produces 800 lumens only uses 15 watts to power it.
How many lumens is bright enough?
Lights of 100 lumens are bright enough and offer a decent amount of light for walkways or some other outdoor area. However, you can use up to 300 lumens in an outdoor area if you want to make it a bit brighter. The brightness of 100 lumens equals 20 watts!
How is the brightness of a CFL bulb determined?
Brightness is determined by lumens. Lumens is best described as the measurement of light. A single CFL and LED bulb might have the same lumen (brightness) output but vary greatly in the amount energy needed to generate that level of brightness.
Which is more energy efficient LED or CFL?
LED bulbs require much less wattage than CFL or Incandescent light bulbs, which is why LEDs are more energy-efficient and longer lasting than their competitors.
What’s the life expectancy of a CFL bulb?
The next best are CFL bulbs which bring in a respectable 8,000 hours of average life expectancy. Keep in mind, most tests are based on a running time of 3 hours per day. The past year has been unique. This is an understatement of epic proportions.
What does lumens mean on a light bulb?
Lumens, not watts, tell you how bright a light bulb is, no matter the type of bulb. The more lumens, the brighter the light. Labels on the front of light bulb packages now state a bulb’s brightness in lumens, instead of the bulb’s energy usage in watts.
