I refer to the twist-in types where you reach behind the instrument and twist the thing in and out (if you have small hands and gymnast body). I believed B8.5D was most common type, with a T5 wedge bulb in it. Nowadays it probably has a LED that is not removable. Anyway, I see some catalogues also list "BX8.5D" bulbs that are similar. What is the difference.
