I'm in the process of building my own coolbot to control walk in cooler AC unit. I need a heater that tricks the AC thermometer into thinking the room is warm. I see some guys using light bulbs but Id like to use something smaller and more professional, something like the heaters in 3d printers. I imagine these get way hotter than I need. Do they make these to where they get to around 70-100 degrees or so?
