These are the HLX-series bulbs, also branded "Xenophot," made by Osram. They are highly recommended for any projector you can fit one to. If Osram ever made an ESC this way, GS owners would be in hog heaven. Only dreaming there.
The presence of "Xenon" does not mean this is an arc lamp. Rahter, the bulb enclosure is filled with Xenon gas, which makes it possible to burn the filament hotter without it deteriorating quickly.
The Eumig 810, using an f1.0 "D Lux" lens, and one of these EFP "Xenophot" bulbs, looks like it's a 150W+ bulb. Not only that, but the color temperature is a tiny bit higher than a normal halogen. However, the Don's Bulbs price is a rape-and-pillage proposition ($89 for one! seriously!) where other outlets sell both the long-life and projection versions for around $7. Just Google for it. My understanding is that the 600 hour life is intended for stage lighting and will have a different look (warmer color, maybe a little less brightness) than the 50-hour version. I have not personally verified this. However, either way it's only $7, and the filament from Osram is a desirable C-8 instead of a C-6, so it's not much to risk losing. Unless you buy from Don.
