How to build a thermoelectric lamp

Step 11 Fit the peltier

Now you can fit the peltier to the heat sink. Press it down into the thermal compound and wiggle to smooth out the compound. You can see that the peltier is very dirty from soot, this is from my testing.  The side that is in contact with the heatsink must be clean though. When you use the device dry and avoid getting soot on the peltier as it blocks the heat transfer. Use the candle height adjustment to get this right.
