  • SpectrumLED- An INSANELY Bright 200 WATT Variable Spectrum LED Panel

    A couple of suggestions to improve this instructable.Provide specifics on the heat sink. Like block size, fin size, count and weight. Being able to repurpose a heat sink from audio equipment is great, but not just any will do. As an example, the Phase Linear 400 is designed to dissipate 400 watts nominal, but would not be sufficient for 200 watts continuous.A heatsink designed for the task (cast or extruded) would probably increase the price of the build 5X.Making a heatsink out of aluminum bar and angle stock is possible but structural aluminum is not quite as good and you end up with lots of interfaces (mating surfaces) that reduce efficiency.Consider using thermal paste and screw the LEDs to the heatsink instead of gluing them on. Thermal paste has better heat transfer properties and...see more »A couple of suggestions to improve this instructable.Provide specifics on the heat sink. Like block size, fin size, count and weight.

Thermal paste has better heat transfer properties and there is no worry of it popping off with screws.Oh, and 5 watt resistors are surprisingly pricey. That cost was not included in this build.
