I just found out that thermal tape comes in big long thin rolls, and apparently works quite well too.

This is perfect though for use in the wacom monitor, since it makes it safer to over power the backlight, and have reliable heat control.

Also, many LED backlight kit suppliers also sell the rolls of thermal tape.

A quick warning though, the LED strips are actually somewhat fragile, so, once stuck in there, given how strong i know thermal adhesive to be, its going to be very difficult to pull the LED strip out again.

The results of this ebay search should show you what thermal tape is. Dont mistake it for thermally insulating tape, or kapton.

Thermal adhesive tape is like a sheet of goo between two peelable sheets, the kind i usually see is black, but color doesnt matter. Get some intended for computer use if you are unsure, or otherwise the absolute thinnest stuff possible. Whats more important here is that it adheres without insulating, unlike normal double sided tape which would probably insulate or eventually dry out from the constant heat.

Also, i will be buying some thermal tape to use with peltier coolers.  One of the main problems ive always had with peltier cooler plates was how difficult it always was to keep the heatsink in place, since it always tended to kind of slide off, but with an adhesive thermal compound, it opens up new possibilities. Should make things a lot easier for the greenhouse climate controller im working on, or rather, have thought about but am still trying to put things together. But with adhesive tape that conducts heat, i should be pretty much set to build a prototype now that i dont need an elaborate case to hold everything together.

On another note, this also means its easier to stick high powered LEDs onto heatsinks without machining them.

Its just such a useful product ill have to go and buy a whole bunch of it XD
