Spectrum of a UHP lamp of a media projector

I captured this spectrum from an Epson media projector, when I was at a 3D printing class for people with disabilities like intellectual disability. This was a year before the COVID-19.
The mercury pressure here is 200bar, and the mercury lines are very wide and almost merging with the strong continuous molecular spectrum.
There is a strange dark line at the mercury green band which I don't know what it is, since the optical mercury lines aren't resonance lines.
A higher resolution spectrum:

Unfortunately, even in media projectors, HID loses to LED, as it is much cooler and smaller, so the media projector can be very small, but LED don't have so interesting spectrum like UHP.
