Luminous flux in lumens (lm) to illuminance in lux (lx) calculator and how to calculate. Enter the luminous flux in lumens, select area unit type, enter radius in meters for spherical light source or surface area in square meters for any light source and press the Calculate button to get the illuminance in lux: Lumens to lux calculation formula Calculation with area in square feet The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous flux ΦV in lumens (lm) divided by the surface area A in square feet (ft2): Ev(lx) = 10.76391 × ΦV(lm) / A(ft2) 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 The illuminance Ev in lux (lx) is equal to the luminous flux ΦV in lumens (lm) divided by the surface area A in square meters (m2): Ev(lx) = ΦV(lm) / A(m2) The illuminance Ev in lux (lx)...

How does DMX lighting work? DMX cables can send 512 channels of data from the controller to the light fixtures in your system. You can set each channel to a value of anywhere between 0 to 255. The DMX controller acts like an audio mixing console, mixing light instead of sound. This group of 512 DMX channels is called a universe. 256 values per channel over 512 channels is a lot of data. That’s why specific DMX cables are required. They may look like XLR audio cables, but the actual cable between the connectors is different and designed specifically for this job. We always recommend using the proper DMX cable. How do DMX lights work? So with up to 512 channels of data coming from one cable, how does each light know what to listen out for? Each light has two settings that let you specify how you want it to behave. Mode This is specific to each light model, and you will need to refer to the manual for details of how the light responds in each mode. For example, in 4 channel mode, our ...

Making High Power LED light is not always an advantage, maybe bring greater risk!!! According to the marketing feedback, some clients bought 500W – 1000W LED flood light from China. And they found the color temperature turned to blue or yellow, and the luminance reduced 60 – 80%. Why?? LED has many advantages, and brings new challenges. But LED is a light source but not new sports lighting solution. So there are many small LED suppliers moved from Red Sea Market to high-power Blue Ocean Market in the lighting market today. However,  since most manufacturers are doing the same job. That is to choose some radiators that looks very unique from the market A, and buy driver from B, and but light source from C, then buy reflector from D and assemble them into finished products. We will find an interesting rule, that is, all of them don’t have their own R & D team. They are all looking at what profitable products the next door do, then follow. We all know making a good outd...

When the venue uses four-tower, multi-tower or tower-band hybrid lighting, it is necessary to use the lighting pole as the carrier of the luminaire. In the case that the lighting pole meets the requirements of the lighting technical conditions, the relationship with the building mainly has the following ways. (1) The light pole is independent of the main building. This kind of light pole exists as a separate device and is widely used at present. (2) The lamp raft is attached to the main building, but it is not integrated with the main building. The foundation of this form of stadium light post may be different from the basic form of the building and must be treated separately. (3) When the light pole is attached to the main building and integrated with the main building, this form can handle the aesthetic problem well. If this scheme is feasible, this scheme can be prioritized. When the light pole is combined with the building, the light pole and its setting must meet the relevant r...
