I just built this unit for a friend. IMHO it's best to purchase a lighting controller that exceeds any CSA/UL/ETL/CEC/NEC requirments. The RANCO has two stages, stage one temp shuts off one light at a time till temp lowers to preset, then rotates to the next light to turn off when temp rises. Stage two temp kills all lights in 60 seconds.
nice can it looks well thought out do you have any visual trip indicator for the over temp protection?
