A 23 watt cfl will give off roughly 1600 lumens. However that is only within a few inches of the bulb.

What does A 170 lumen flashlight equal in a watt flashlight?
The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
How many lumens does a a 1 watt led bulb produce?
Generally speaking, the lumen per one watt of different LED is different. As far as i known, some LED products can reach 120 lumen per watt or more higher which from lab or some big famous comapny, we called this is lab level, but in fact, most of companies and LED manufactures can not reach this level, theirs LED products are differenet, some of they can reach 80~90 lumen per watt, but some is very low, like companies power, technical level, product develop and many others factor will effect the lumen level. Of course, all of this conclusion is base on the test report of LED product, like lumen, color temperature, CRI, illuminances etc parameters.
What is the lumen output of a 60W incandescent bulb?
The output of bulbs varies. A typical output of a 60W incandescent bulb is 680 lumens.
How many Lumen's can a 60 watt bulb produce?
This depends on the type of bulb and it's efficiency. Incandescent bulbs produce 700-900 lumens at 60 watts.
How do you transfer watt to lumen?
When measuring light, the lumen and the watt both measure power -i.e. the rate at which electromagnetic energy is emitted (for visible light, this 'power' is termed 'luminous flux'). Although they are both SI units, one (the lumen) is used in the photometric system of measurement, whereas the other (the watt) is used in the radiometric system of measurement. Whereas the watt is used to measure the total rate at which electromagnetic energy is emitted from a light source, the lumen is used to measure only the visible part of the spectrum and, then, corrected for the sensitivity of the human eye (the eye is most sensitive to the green part of the visible spectrum. The watt, of course, can also be used to measure the input power to a lamp.In the radiometric system, the input and output powers of a light are each expressed in watts, but in the photometric system, the input power of a light is expressed in watts, but the output power (luminous flux) is expressed in lumens. The ratio of a light's output (in lumens) to input (in watts) power, is termed efficacy (NOT 'efficiency'), and it various according to the type of light. An incandescent lamp, for example, has an efficacy of up to about 15 lumens per watt, whereas a fluorescent lamp has an efficacy of around 50 or so lumens per watt.
What is the lumen output for a 52 Watt halogen bulb?
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
What energy saver bulb given off 1750 lumen?
That would be approximately a 30 watt CFL.
What is better a 105 watt CFL bulb or 5 23 watt CFL bulbs?
A single bulb is better if you can get it, it's simpler to use, but 23 watt bulbs are easier to find. Five 23 w bulbs totals 115 watts so they would be a little brighter.
What is brighter 2000 lumen watt bulb or a 1500 lumen bulb?
This question is ill posed. Lumen is a unit of measure for how much light comes from the lamp Watt is a unit of measure for how much energy is used by the lamp If the question were; "Which is brighter, a 2000 lumen bulb or a 1500 lumen bulb?" then the answer would be: The 2000 lumen bulb. I think the relation ship between lumen and watt is something like: Incandecent bulbs are 15w/lumen Flourecent bulbs use 40w/lumen LED bulbs are 70w/lumen The way to show the watt and lumen relationship is usually lumens (amount of light) per watt (energy consumption). This is like gas in your car (Miles or KM per Gallon or Liter). Incandescent bulbs have a maximum luminosity of 52 lumens/watt. Fluorescent bulbs range from 46 lumens/watt (CFL) to 100 lumens/watt (T5 and T8 tubes) LED bulbs range from 29 lumens/watt (older, low efficiency) to 100+ (XCree) and they are getting better.
How many lumens does a 42 watt CFL give off?
a 42 watt cfl give off 2800 lumens
What LED bulb same as 13 watt CFL?
A 13 watt cfl is the same as a 60 watt incandescent. So find an led bulb that is equivelant to a 60 watt incandescent
What is the percentage of light output between CFL bulbs and an incandescent bulb?
Incandescent: 10-12 lumens per watt CFL: 50 lumens per watt.
Can you use a 13 watt CFL bulb in place of a 60watt incandescent bulb?
no because it would blow up because the socket would draw 13 watt not 9 watt
Can you use a 100 watt CFL in a fixture that says the bulb should not exceed 25 incandescent watts?
Probably, as the CFL consumption is 26 watts. Why not try a 60 watt CFL first, that would be much lower consumption.
How many lumen's are in a 5 watt led lamp?
25
Lumen per watt for halogen bulbs?
around 20
What is the lumen's of a 70 watt metal halide lamp?
6000lm
