# lux conversion factor

So @Sxott,the conversion factor for a 3k Cree would be … In reality, however, obtaining a light source's exact SPD is not an easy task for the average grower - it requires expensive spectrometer equipment. Illuminance in lux plays a major role in the planning of lighting installations. This is really the only meaningful difference between the two anyway. So the illuminance in the light circle is not homogeneous. Especially in the peripheral areas, the luminous intensity usually decreases. Since it is the emitted light on the one hand and the received light on the other hand, other factors also play a role. Or find the lux-par conversion factor in one of the threads on this subject here or get it from Apogee's site. 50 lux to fc = 4.64515 fc. Lux to Kilolux (or just enter a value in the "to" field) Please share if you found this tool useful: Tweet. I think that understanding this relationship, goes a long way in getting comfortable with these lighting terms. If you need to convert foot-lambert to another compatible unit, please pick the one you need on the page below. Jun 21, 2012, 11:13 pm. The online calculator will help you to find a reference point for your lighting design. Lux measures the number of lumens within an area of one square meter. Conversion Tables. - Kwatt to amp calculator. Unit Descriptions; 1 Kilolux: 1 Kilolux is equal to 1000 Lux (SI unit). The approximate conversion factors given below will help to convert absolute energy units or irradiance units (PAR) as recommended by the plant scientist into illuminance or photometric values (lux). With a lower cost and higher sensitivity in low light conditions, light meters measure luminous flux per unit area (illuminance) utilizing the units of lumens per meter squared or lux (lx). If you need to convert foot-lambert to another compatible unit, please pick the one you need on the page below. - Utilisation factor calculator. 7 Recommendations. Use this page to learn how to convert between lux and fc. If this article helped you, please share - thanks! Lux to GigaLux. taz3m Guest; Re: LDR reading to lux conversion. - DC efficiency calculator. #5 Jan 10, 2013, 07:01 am. At Metal Supplies it doesn’t matter if you need non-standard sizes or you have an unusual request. 10 lux to fc = 0.92903 fc. - CIBSE lighting LUX level recommendation. 1 lux to fc = 0.0929 fc. Hello to all, I just been wondering what can be wrong with my program code, as my result is returning to zero though all my other variables are giving correct values. The ... lux (SI unit) lx ≡ lm/m 2 = 1 lx = 1 lm/m 2: phot (CGS unit) ph ≡ lm/cm 2 = 10 4 lx Radiation – source activity. Solar Radiation is a shorter wave length and different color spectrum, so it has a different factor of Lux to W/m2: Bright sunlight is approximately 136000 lux = 1075 W/m2 = 126.7. After a click on the Calculate button you will see the size of the illuminated area and the lux value. These are the beam angle and the distance between the light source and the illuminated surface. One lux is equal to one lumen per square meter (lux = lumens/m 2). Illuminance levels can be measured with a luxmeter, shown in Figure 1.7.2, or predicted through the use of computer simulations with recognised and validated software (e.g. Lumens Per Square Meter to Lux (or just enter a value in the "to" field) Please share if you found this tool useful: Tweet. This is the luminous flux emitted by the lamp in all directions. Topic: Convert LDR's resistance to lux, or another unit of light? For monochromatic light of this wavelength, the irradiance needed to make one lux is minimum, at 1.464 mW/m2. We can convert that reading to W/m2. I have seen anything from 10 to 80 and have read that the more blue the higher the conversion factor so the lower the par. 1 Footcandle is equal to 10.7639104167097 Lux (SI unit). ›› Quick conversion chart of lux to fc. Converting Lux to W/m2 • There is no simple conversion….it depends on the wavelength or color of the light. 40 lux to fc = 3.71612 fc. Reactions: Mars Hydro, labexperiment, FelipeBlu and 2 others. There is no single conversion factor between lux and W/m 2; there is a different conversion factor for every wavelength, and it is not possible to make a conversion unless one knows the spectral composition of the light. There is no exact conversion factor.
