The Event kit
Hire one power unit for every 10m of tape/ 4 channels of control
Each 240w PSU will supply 10m of 60led/m RGBW tape when running all colours at 100%
You can connect more tape if using only one of the colours, the limitation is the power supply which will cut out so there is no danger of overload.
If you are extending the cables for any distance please remember to use larger cables to reduce voltage drop.
