Subtractive color mixing uses a white light source with a series of filters to eliminate certain wavelengths of light. Typically, these systems are known as CMY (Cyan, Magenta, Yellow) color mixing and consist of dichroic filters.

The protocol can address 32768 DMX "universes", each of 512 channels, limited by bandwidth. The fixed addressing can be problematic in networks with other addressing requirements.  

Art-Net is a communication lighting protocol for transmitting DMX and RDM signals over Ethernet. With 2 universes of bi-directional eDMX to DMX conversion with ArtRDM support, power over ethernet (PoE), or flexible 12-24v DC input, the DIN Ethergate allows for fast deployment of DMX systems.

Illuminance is the transmission of natural light (windows, lighting plates... ).  Lighting is the distribution of artificial light (Lamp, floor lamp, neon...)

This can be measured in candelas/square meters (cds/m2) or foot-lamberts (fLs). Illuminance, on the other hand, describes the measurement of the amount of light illuminating the surface area and is measured in lux or foot candles and correlates with how humans perceive the brightness of illuminated areas.

Usually, 3 types of packages for stage lighting transportation, are cartons, plywood, and road case (fly cases). The cost is road case＞plywood＞carton. Carton is the basic package and free, least weight and smallest size to save shipping freight, suitable for selling the business, fixed install permanent lights or having own local cases supplier.
