Not the exact bulb as Bulb B (36W), but this 25W bulb: https://www.amazon.com/GMY-Light-Ultraviolet-Bulb-Ozone/dp/B088LPWD18 has the right specs (253.7nm wavelegth), just a little bit weaker. I haven't tested this particular bulb, but it should yield the same results as Bulb D, but without Ozone generation. I'll update the Google Sheets with this new bulb as alternative to Bulb B.
