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.
What is the conversion factor from foot-lamberts to foot-candles?
The conversion factor from foot-lamberts to foot-candles is 3.426.
What would you use to measure the brightness of a light bulb?
You can use a light meter to measure the brightness of a light bulb. This device measures the illuminance or luminance level produced by the light bulb and gives you a numerical value for its brightness in units such as lux or foot-candles.
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.
Do frozen candles burn at the same rate as room tempetured candles?
No, frozen candles will burn slower than room temperature candles because the cold temperature slows down the rate of combustion. The wax in frozen candles will take longer to melt and be consumed, resulting in a longer burning time compared to room temperature candles.
What is unit of illumination?
Light intensities are usually measured in candle power. What that means is the equivalent of the light of one candle, measured at a distance of one foot, sometimes called, `foot candles' or `candellas'. +++ In the SI system the flux or "amount" of light, is measured in lumen; and the illuminence or brightness of the light, on a surface in lumens per square metre, a compound unit called the lux.
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.
What is the conversion factor from foot-lamberts to foot-candles?
The conversion factor from foot-lamberts to foot-candles is 3.426.
How bright is 120 lumen?
one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40，imagine how it is bright.
What would you use to measure the brightness of a light bulb?
You can use a light meter to measure the brightness of a light bulb. This device measures the illuminance or luminance level produced by the light bulb and gives you a numerical value for its brightness in units such as lux or foot-candles.
How many lumens to light a room?
The number of lumens needed to light a room depends on the size of the room and the desired level of brightness. As a general guideline, you can use around 20 lumens per square foot for general lighting. For example, a 100 square foot room would need approximately 2000 lumens for good lighting.
How many lumens make 1 ANSI Lumens?
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.
How bright is 500 foot candles?
500 candelas at 1 foot distance
70 foot candles equals to?
23.33333_ lux
How many foot candles are suggested for a retail store?
It depends on the atmosphere of the store. For example, Best buy uses automated lighting with dimmable ballasts to maintain a light level of 55 foot candles.
Which candles would burn longer cake with 8 candles or cake with 7 candles?
As long as they were all lit at the same time, they would burn for the same amount of time (regardless of the number of candles).
What unit measures light intensity?
in foot-candles. i.e. the brightness of a candle one foot away
