I think these are close to what you have designed. What do you think Dave? For those you may be thinking about doing the same? I recently used them to warm a spot and my salvadorii loves it. I plan to find a way to mount one vertical into the substrate to create temps in mid 80's so I can start finding my salvadorii eggs easier. My ackie is easy and lays 6in away from my center lights beam on the ground and is normally about 13ins down. Temps are mid 80s and just right on the moisture.
