Makers SLIM Heatsink: The t-slots.

t-Slots for Ease of Use and Flexibility

MakersLED SLIM Heatsink t-slot AnimationMakersHEATSINK SLIM uses “t”-slots for ease of LED mounting and re-configuring (patented and pending).

Why be locked into a particular LED package, color spectrum, or vendor when you don’t have to?

Why use screws? Screws help reduce the thermal resistance of your LEDs – by increasing contact pressure with the heatsink, keeping LEDs cooler.



Makers SLIM Heatsink - Get Mounting Your LEDs

How Many LEDs?

The kit includes enough hardware to mount 25 LEDs per foot. The heatsink has enough area to mount ~85 star LEDs/foot, but it is not practical to keep this many LEDs cool in such a small area.

MakersHEATSINK SLIM is a solid extruded piece aluminum with no large milled out fan pockets or thermal voids.

A 1 foot SLIM heatsink in open air will cool approximately:

  • 33 watts of LEDs with no fan
  • 85 – 100 watts of LEDs with a Fan
    • Example: One Lumia 5.2 @ 70W will run at a cool temperature of 85F [29C] on the backside of the the heatsink (with a fan)

If you need more cooling power, check out the heavier duty classic MakersHEATSINK.
