What measures the luminous intensity of a light?
Lumens
What is a measure of light called?
Light intensity is measured in LUX, which is defined as LUMENS/square meter. Lumens derives from the base unit CANDELA.
Are lumens and foot candles the same?
Lumens and foot candles are not the same. A lumen is a measurement of the intensity of light, a foot candle is a measurement of lumens per square foot.
How many lumens per watt?
161 lumens I believe the above answer to be inaccurate. It depends on the light source. For example: For an incandescent light bulb 1 watt it is approx. 18 Lumens. However most LED's use only about 10% the wattage to produce the same amount of light. So for LED's .1 watt produces 18 Lumens.
What is of light-bulbs measured in?
Watts and lumens
What is the dimenion of light intensity?

How many lumens equal one volt?
No telling. Volts are a measure of electric potential. Lumens are a unit for light intensity. Different bulb types with the same input voltage will yield different lumens out.
The rate at which light energy flows through a given area of space is reffered to as its?
The answer is 'luminous intensity' which, in SI, is expressed in lumens.
What is a light bulb measured in?
The unit for intensity of light is candela(cd). However, bulbs are rated by their power usage which is measured in watts(W)
When light is reflected are the lumens reflected too?
Yes. The lumen is a measure of the strength of light; if light may be detected , it is done via the presence of photons, their intensity is the measure of luminosity.

What is the luminance of Streamlight flashlights?
On Amazon, there is a Streamlight flashlight, model 74301, that has five different settings and three different types of luminescence. On high, the peak beam intensity is 10,000 candela -160 lumens. On medium, the peak beam intensity is 5000 candela - 80 lumens; and on low, the peak beam intensity is 2500 candela - 40 lumens. According to the website Learning Centre, Streamlight uses gas-filled lamps that provide a high output and a more natural light.
What happens to the power of the objective as the light intensity increase?
Increases
How many lumens does a 75w agro-light put out?
700 lumens
