History
Feb 2020: Marked some bulbs as contaminated, but keep at least one to show what contamination looks like
Jan 2021: New sodium bulb purchased. Dr. Yi notes that it requires some time (~ 1 min) to heat up to see all lines, since it is in solid state at room temperature.
Feb 2021: Already see some blackened areas on inside of new sodium bulb, some faint contamination seen on spectrum
Feb 2021: Mis-seated or failing bulb caused damage to the lamp housing, melting plastic on one end. This also burnt out the mercury bulb. Switched to spare mercury bulb, need to replace.
