This is due to a Patented computer chip program that can produce colours such as purple, lime green, pink, cyan, as well as the standard red, yellow, green and blue. These come standard on the chip but custom colours are avaliable, please ask for a quote on your specialty needs.
The micro switches used to set the static colours or start the scoll and the speed switch for the continuous scroll are situated behind the end cap and are activated by a simple push of a pen nib or similar object.
They are accessed via 3mm holes in the end cap just above the power plug socket. One control module can run up to 2400mm of PCB off a single 12VDC, 2.5 amp power plug pack.
The low voltage makes the units safe, simple and economical to install as they do not require the expertise of a qualified electrician.
The PC boards are 600mm in length and after the first 150mm (controller section) can be separated every 75mm and daisy chained to suit your size requirments up to 2400mm long. The LEDs are spaced 25mm on centre. The light produced will illuminate engraved or lasered panels up to 600mm, depending on the amount of graphic, evenly and colourfully.
