After some research, I found that OSRAM (the OEM bulb for this projector) has their own amazon store. And they do sell just the bare bulb. It's part number: osram p-vip 240/0.8 e30.1 https://www.amazon.com/OSRAM-P-VIP-240-0-8-E30-1/dp/B08SR4P7HM

Only $60 vs the $126 at Pureland supply for the whole assembly.

And yes, I know not to touch the bulb with my greasy fingers :)
