In which positional order are the LED bars and light colours installed?

You have a completely free choice in this. We recommend you take a few minutes and test various alternatives. Then decide on which one looks the best to you. From our experience, a beautiful optical effect of depth is created when warm light colours (low Kelvin values) are placed towards the back with brighter whiter light colours towards the front. Moonlight, on the other hand, is better at the back. The influence of any specific positional order depends on  how closely the individual LED bars or light colours are installed together.
