DIY LED light for planted tanks

[ILLUSN]

sorry to Necro an old thread but I thought I'd give an update on this original light 4 years on.
it got a slight remodel to cluster the LEDs and remove the disco effect but the base LED's are the same except for the whites which were replced with 6500k T6 XML's and a mix of green (535nm and turquoise 500nm) added to the mix to change the harsh purple to a cooler white light. 60 degree optics were also fitted to better focus the light and help with the colour mixing.
just as an FYI the original 6500k epistars are now lighting up my transformers display cases and are still going strong.
the new layout is shown below.

I can safely say that after 4 years of 12 hours a day these little diodes (the blue and red) have truly proved their worth. I'll run the par meter over them when I get the chance, even without the baseline I'm not expecting much degradation given the crazy cooling I built into this light.
