Can you calculate lux from lumens?
Lumens: The total output of visible light from a light source is measured in lumens. One lux is equal to one lumen per square meter (lux = lumens/m2).
How many lumens is a lux?
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. One lux is equal to one lumen per square meter. It enables us to measure the total “amount” of visible light present and the intensity of the illumination on a surface.
How much is 1600 lumens?
The brightness, or lumen levels, of the lights in your home may vary widely, so here’s a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for fewer lumens; if you prefer brighter light, look for more lumens.
How bright is 1200 lumens in Watts?
What wattage light bulb do I need?
| Lumens | Incandescent bulb (12-18 lm/W) | LED bulb (80-100 lm/W) |
|---|---|---|
| 480-720 lm | 40 W | 7 W |
| 720-1080 lm | 60 W | 10 W |
| 900-1350 lm | 75 W | 13 W |
| 1200-1800 lm | 100 W | 17 W |
How many watts is 1350 lumens?
What wattage light bulb do I need?
| Lumens | Incandescent bulb (12-18 lm/W) | LED bulb (80-100 lm/W) |
|---|---|---|
| 300-450 lm | 25 W | 4 W |
| 480-720 lm | 40 W | 7 W |
| 720-1080 lm | 60 W | 10 W |
| 900-1350 lm | 75 W | 13 W |
How many watts is 1300 lumens?
| LED Wattage | CFL Wattage | Lumens |
|---|---|---|
| 6W | 12W | 700 lm |
| 9W | 15W | 900 lm |
| 12W | 20W | 1,300 lm |
How to convert Lux to lumens in calculator?
Lux to lumens calculator Enter Illuminance in lux: lx Select area unit type: Or enter surface area: Luminous flux result in lumens: lm
How to calculate the illuminance of a lumen?
The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous flux ΦV in lumens (lm) divided by 4 times pi times the squared sphere radius r in feet (ft): Ev (lx) = 10.76391 × ΦV(lm) / (4⋅π⋅ r(ft)2) Calculation with area in square meters
How to calculate the lumens of a spotlight?
Example: An illuminance of 300 lux should be generated on a surface 6 ft below a spotlight with a beam angle of 30°. You want to know how much lumens the spotlight must have. In the calculator, select Lux to Lumen as Conversion and enter 300 as the lux value, 30 as the beam angle and 6 as the distance.
How is the luminous flux E V ( LX ) calculated?
E v(lx) = Φ V(lm) / A (m2 ) The illuminance E v in lux (lx) is equal to the luminous flux Φ V in lumens (lm) divided by 4 times pi times the squared sphere radius r in meters (m): E v(lx) = Φ V(lm) / (4⋅π⋅r 2 (m2 )) Lumens to lux calculation ►.
