Make your own heatsink. Its cheaper and easy to do.

You have to build your own heatsink. Head out to metal supermarkets (http://www.metalsupermarkets.com/nonUS/) and pick up a 'slab' of aluminium. Buy some 90 degree 1 x 1 angle aluminium and mount them to the slab. Just drill and tap or just use self tapping screws. Make sure you put a thin layer of dielectric (looks like white grease) in between the 2 pieces.

It'll be cheaper this way as a real heatsink that size will cost you a fortune.

The aluminium is sold by the pound.

or you can buy this from ebay..........http://cgi.ebay.com/NEW-HEATSINK-ALU...QQcmdZViewItem for $50USD / foot whichincludes shipping charges to Canada.

Good luck

i will try metal supermarket in calgary,and thats my last stop before i purchase the heat sink from HeatsinkUSA.
man the price for the size i need in town is like 170$ a foot for the smallest size of 6ft.

check with a scrap yard, alot of industrial electronics use huge heatsinks and they get sold to the scrap dealer if the device breaks.
I think i have one huge heatsink at work that is in our scrap bin probably 24" X 40" with 6" fins.

just build your own. use 90 deg angle of u channel.

at 170$ / foot, might as well buy the pfo led light system pre-built.

tell what you decide to do

i will be placing my orders for power supply,drivers, luxeon led and some cree led for a DIY array for my 40glns reef next week.
i will be detailing the progress in the DIY section.
i have been testing some of them in the past month.
i love the colour i get from the royal blue and whites.

the pfo led light system is out of business and you can build one for half the price.
