How do you calculate the lux level of a room?
Notes: Lux: Lux (Illuminance) is a measurement of the light intensity at any point. It is equal to 1 Lumen per square meter….Light Quantity Calculator.
| Room Size: | Width x Length: | x meters |
|---|---|---|
| OR Area: | m2 | |
| Room Type: | Bedroom / Hallway (100 Lux) Lounge – Minimum (150 Lux) Lounge – Well lit (250 Lux) Office (400 Lux) | |
How are illuminance levels calculated?
While illuminance measures light incident on a surface, luminance is the light emitted or reflected by that surface in candela/m2 or “nits”. The values of luminance L and lux E are related through an ideal surface that emits all light with the equation E = L x π.
How many lights are needed in a room calculator?
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
What does foot candle mean?
A foot-candle (or foot-candle, fc, lm/ft2, or ft-c) is a measurement of light intensity. One foot-candle is defined as enough light to saturate a one-foot square with one lumen of light.
