@chelseya We have not tested PIC100 but would expect it to require 45C for 2hrs which has been our recommendation (and is the preset) for castable materials.
Our recommendation for lamp replacement is 1,000 hours, but we have no data to suggest they won’t run longer than that. The only way to know for sure would be to monitor the radiometric power output of the lamps and that requires special and expensive sensors. Its best to change them regularly. They are relatively inexpensive at $32/set of four.
CUREbox has a one year warranty. There is no option to purchase additional warranty. You should not expect it to last just a year though. It is built from quality materials and meant for daily use in a lab environment.
