What is a 20W CFL equivalent to?

100W incandescent
Efficiency and running costs The higher the wattage, the higher the running cost. The light output from a 20W CFL isn’t the same as that from a 20W incandescent. Rather, a 20W CFL would be the equivalent of a 100W incandescent (roughly 20%).

What is a 20 watt energy saving bulb equivalent to?

100w
PHILIPS ENERGY SAVER BULB 20w (EQUIVALENT TO 100w)

What is the CFL equivalent to 60w?

15-watt
Remember this rule of thumb: CFLs use about a quarter of the wattage to produce the same light. So to replace a traditional 60-watt bulb, buy a 15-watt CFL: 60-watt incandescent / 4 = 15 watts. Note: Some brands of 60-watt equivalent CFLs still do not seem to give off as much light as a 60watt incandescent bulb.

How many watts is a CFL?

Compact fluorescent bulb wattage ranges from 11 to 42 watts. They use 75% less energy than the equivalent incandescent bulbs, which range between 40 and 150 watts. Some of the most common CFL wattage equivalents are 13 watt CFL (equivalent to 60 watt incandescent) and 23 watt CFL (equivalent to 100 watt incandescent).

Why is CFL better than LED?

CFL’s use 25-35% less energy than traditional light bulbs, or incandescent bulbs, use. This means that LED bulbs are incredibly energy efficient. Additionally, CFL bulbs release almost 80% of their energy as heat, while LED bulbs emit very little to no energy as heat, which increases their efficiency even more.

What is a 13w CFL equivalent to?

60-watt incandescent
For instance, a 13-watt CFL is equivalent to a 60-watt incandescent.

Should you replace CFL with LED?

So, is it worth switching from CFL to LED? If your CFL bulbs are working, it’s usually not worth replacing them with LEDs immediately – LEDs are more efficient, but the savings aren’t huge. Only replace them now if your CFLs aren’t suited to the fitting or are damaging fabrics. Otherwise, wait until they’re burned out.

What is the wattage of a CFL light bulb?

A CFL bulb that produces the same amount of light as a 60 watt incandescent bulb (900 lumens) only uses around 15 watts of electricity. So you can put a CFL in the fixture that equals the light output of a 100 watt incandescent (1,600 lumens) and still only use 25 watts of electricity.

What is CFL wattage?

The light source is an 11-watt compact fluorescent lamp (CFL) powered by a dc ballast with a total system wattage of 13 watts. The CFL will be turned on for eight hours of operation at night per day.

What is the wattage of a lamp?

Power can also be expressed in terms of the resistance of a device: Different streetlights consume different amounts of energy. Incandescent lamps typically range from 25-150 watts, fluorescent lamps range from 18-95, metal halide lamps range from 50-400 watts, and high pressure sodium lamps range from 50-400 watts.
