lightsource

Geleen & Psylant; Thanks to both of you for your replies and advice. That gives me a great start and some modification targets to what I've built already. Many thanks!

It is a matrix of LED's of different wavelengths, carefully chosen in wavelength, bandwidth, and power in order to provide a precise solar illumination. The device is currently used in solar catalysis work, but I am wondering what features might be desired for aquarium use.

I am an Edmontonian who has developed a spectrally tunable light source, and am trying to find out if it may be of interest to those owning aquariums. The light can provide a near perfect match to the intensity and wavelength distribution of the solar spectrum, or instead emphasize parts of the spectrum that may be important for growth of plants or for optimizing the perceived colour of fish. It could cycle day/night or could mimic the spectrum hitting the ocean at any point on the globe (or the underwater spectrum at a prescribed depth). Currently I am looking at applications to solar cell calibration and botany research. However I know little about the needs of aquarium owners and wonder if this type of lighting is advantageous and whether the instrument should be modified specifically for aquarium use. Thanks for any comments or replies!
