Does 1 lux equal 1 lumen?
One lux (1 lux) of light is a measure of the light density, equivalent to 1 lumen per square metre (lm / m^2).
How do you convert lumens to lux?
One lux is equal to one lumen per square metre: 1 lx = 1 lm/m 2 = 1 cd · sr / m 2. A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux.
How do you convert lumens to Candela?
1 candela = 12.57 lumens However, note that directly comparing lumens and candela values of lighting devices is not wise.
How many lumens is 30 foot-candles?
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.
How many lumens is a square meter?
The current regulations indicate that to illuminate an office, for example, we recommend about 300-400 lumens per square meter of surface. Therefore, if your goal is to illuminate an area used as an office whose surface is 100 square meters, the light potency you will need will be around 30,000-40,000 lumens.
What is the difference between lumens and footcandles?
Though this is similar to a Lumen, as alluded to above, there is a key difference, which primarily focuses on the fact that a Lumen is a measurement of the light emitted from a source, while a Foot-Candle is focused on the amount of light that impacts a surface a given distance away from a light source.
How many lux is a 60 watt light bulb?
800 lumens
For example, a 60-watt incandescent bulb produces about 800 lumens of light. By comparison, an LED (light-emitting diode) bulb produces that same 800 lumens but uses only about 9 watts.
How can I calculate lux?
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 many lumens is a LIX?
1 lux equals 1 Lumen/m2, in other words – light intensity in a specific area. Lux is used to measure the amount of light output in a given area.
