LedGroupBuy have recently started making a 100w multi-LED chip - see http://www.ledgroupbuy.com/lumia-5-1-100w-full-spectrum-5-channel-led/ for details.
I thought it might be fun to try one of these over the pool - they are designed to cover a 60cm x 60cm area but by raising it a bit I can easily cover the pool.
It incorporates 50 LED's in 5 individually addressable channels including:
Channel 1 - Neutral White (base white spectrum) (36V @ 700mA)
Channel 2 - Royal Blue (base blue spectrum) (36V @ 700mA)
Channel 3 - Hyper Violet (enhanced growth) (38V @ 700mA)
Channel 4 - Deep Red / Turquoise (enhanced color spectrum) (32V @ 700mA)
Channel 5 - True Violet / Cool Blue (enhanced growth and color spectrum) (38V @ 700mA)
At around $110 AUD they are not exactly cheap but given the number of LED's they incorporate it's probably not too bad.
This gives you an idea of the size
I don't really like the way the wires were bent around in the packaging - it is now difficult to get them straight and the tab where they join onto the main body does not look like it would take a lot of bending.
I know that this will generate quite a lot of heat so some sort of active cooling will be required - I am not sure if it will be enough but I am going to start with a CPU heatsink and fan that I extracted from an old computer today
Fits nicely with a generous amount of Arctic Allumina to fix the chip to the heatsink
Now to organise some wiring and fire it up - if you see a glow in the Southern sky then you will know that I got it going :p
