Buy large led heat sink?

[r6justin]

I have a 150 gal 5x2x2 feet tank and currently have 2xt5ho and 1 250w mh. I would like to replace the mh with leds and slowly upgrade. I'm thinking buy a large 4ftx18in heat sink would be best.

Why not get two 4' sections of the new LED heatsink from heatsinkusa?

I would look at tubular aluminum and pressurized cooling fans that blow air through them. I did a StevesLED build and I like the set up.

look into the makers LED heatsink. makes building a light super clean and easy. also leaves the option for adding more later. the 4ft heatsink would come with 4 fans, hardware for mounting leds, and a splash guard i believe. google it and you should be able to find something. i know the LED group buy people sell it for $199

Just use aluminum "C" channel with fans. Way cheaper than heatsinks USA.
