heatsink

[byee]

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.

where are you ordering all this from ??

urls would be great.

is the intent to replace you MH or atinics for the evening ??

do you have a rough costs for your 40gal ?? I've got a 120gal but moving towards a 200gal.

with MH problem, temperature control,bulb replacement every 8mth, high bill,not the output colour i like.

LED array is going to replace total lighting in my reef.
i will be posting everything starting next week,there are few companies i am looking at for best rates.
for starters the purchase is going to be pricey but cheap in the long run.
