Kelvin (K) looks wrong

In most aquarium lighting systems different colour and wavelengths of light are often mixed, this can often produce strange results on the seneye kelvin meter.

Don’t forget each led is really a ‘colour’ on a modern Light emitting diode aquarium lamp, often they are separated by distance and with different beam angles.

Even though it may not be clear to you this method does not give perfect photon (colour) mixing and pools of coloured light are created.  As you move away from the light sources we would expect this to be less pronounced.

On some lamps you can edit the settings like K and when you edit the settings you should expect the more red the lower the K or the more blue light the higher the K.

We do have some info on the main web site that is worth a quick read and can be linked to from below:
