Basis of the calculation
The calculation uses data sheet values at full brightness and white light. Real values differ depending on series resistors, tolerances and ambient temperature. The results are a planning aid and do not replace a design by a qualified electrician.
A DMX512 universe is transmitted at a maximum of 44 frames per second.
