In this context, Watts are a measure of electrical power and lumens a measure of light output. So, depending on the efficiency of your light source the equivalency will vary dramatically. For example, a 60 watt conventional light bulb typically gives off 800 lumens. A frosted 60 watt bulb may only give off 500 lumens. A 13 watt CFL will give off that same 800 lumens, which is why 13 watt CFLs are often (erroneously) called 60 watt bulbs.

How many lumens in an LED to make 60 watts?
There is no direct conversion between lumens and watts for LEDs since they are measured differently. However, as a rough estimate, a 60-watt incandescent bulb produces about 800 lumens. For an equivalent LED output, you would typically need an LED bulb with around 800 lumens.
What is 1.2 lumens in wattage?
To convert lumens to watts, you need to consider the efficacy of the light source, as different types of bulbs produce different amounts of light per watt. For example, an LED bulb typically produces about 80-100 lumens per watt, while an incandescent bulb produces around 10-17 lumens per watt. Therefore, 1.2 lumens would be approximately 0.012 to 0.12 watts for an LED, and around 0.07 to 0.12 watts for an incandescent bulb. The exact wattage can vary based on the type of light source.
Does a lighting fixture use watts or is it the bulb that uses watts because my fixture says 660 watts but the CFL bulb is only 23 watts?
The watts determine how much energy is taken and how much heat is produced. You need to look at the lumens to see how much light is produced. CFLs produce 4-5 times more lumens than incandescent bulbs, or 3-4 times more than halogens, for the same power in watts.
How do you work out lumen's?
To calculate lumens, you need to know the luminous efficacy of the light source in lumens per watt (lm/W) and the power consumption in watts. Multiply the luminous efficacy by the power consumption to get the total lumens produced by the light source. For example, if a 10-watt LED bulb has a luminous efficacy of 80 lm/W, the total lumen output would be 800 lumens (10 watts * 80 lm/W).
What is equivalent lumens of 40 watt incandesent bulb to led light?
Light is a little complicated because various devices for producing it have various efficiencies. Light is measured in lumens. Older incandescent lamps produce 10-15 lumens per watt of electrical power. Halogen lamps produce maybe 20 lumens per watt and lasted much longer. Several years ago the best LEDs were also 20 lumens per watt. Now the best white LEDs are 5 to 10 times better than incandescent lamps, and they last for a decade or more. Expect almost all lamps to be LEDs in the next few years.

How many watts of led equals 40 watts of fluorescent?
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.

How can I convert lux to watts in order to determine the power of light emitted by a source?
To convert lux to watts, you need to know the luminous efficacy of the light source in lumens per watt. Then, you can use the formula: Power (watts) Illuminance (lux) x Area (square meters) x Luminous Efficacy (lumens per watt). This calculation will help you determine the power of light emitted by a source.
What is the lumen's for a 500w halogen light?
Wikpedia says that halogen lamps produce about 19-20 lumens/watt. If you have a 500W lamp then you get 9500-10000 lumens.
How many lumens to equal a watt?
Incandescent bulbs: 10 lumens per watt Halogens: 13 lumens per watt CFLs: 50 lumens per watt A useful bulb to light a small room is 600 lumens, so that would need a 60-watt incandescent, or a 45-watt halogen, or a 12-watt CFL energy-saving bulb. The best CFL bulbs are the spiral ones.

What is 250VA equivalent to in WATTS?
To convert VA to watts, you typically need to know the power factor of the device. If the power factor is 1 (which is often the case for resistive loads like heaters), then 250VA is equivalent to 250 watts. However, if the power factor is different (common in devices with motors or electronics), then the conversion would be different.
37.5 amps converted in watts?
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
Formula to figure out watts when you have voltage and mAh?
Voltage times current is equivalent to power (watts). You need to keep in mind that milli amp hours (mAh) is amps with a unit of time - it's a specific amount of current for 1 hour. Watts is an instananeous measurement; watt hours is the equivalent you should be looking for. there is no direct conversion for watts from voltage and mAh.
