Brightness is measured in lumens so the bulb has a brightness of 100 lumens. The electrical power the bulb uses is measured in watts.

The efficiency of a bulb is expressed in the number of lumens produced per watt of electric power.

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 are in a 10w g4 bulb?

It depends on the make !! A cheap one < 100 lumen, a high quality, say Osram 140 lumen


How many watts does an energy saving light bulb use?

An energy-saving light bulb typically uses between 5-15 watts of power, depending on the brightness and type of bulb. This is significantly less than traditional incandescent bulbs, which can use 60 watts or more for the same amount of light output.


What equation would you use to calculate how much current in AMPs is required to achieve the full 100 to output from a volt bulb?

The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.


How bright is 1400 lumens?

1400 lumens is considered to be quite bright, suitable for illuminating a medium-sized room or outdoor area. It is equivalent to the brightness of a 100-watt incandescent light bulb, making it ideal for general lighting purposes.

How many lumen in 100 watt metal halide?

A 100-watt metal halide lamp typically produces around 8,000 to 10,000 lumens, depending on the specific design and efficiency of the bulb. This lumen output can vary based on factors such as the manufacturer and the lamp's age. Metal halide lamps are known for their bright, white light, making them popular for outdoor and commercial lighting applications.
