PAR 46 it is & it's a hard one as most lamp manufacturers don't list it as other than Medium Side Prong (MSP).
Every lamp manufacturer & every lamp
base manufacturer follows a standardized
system, more a question of what lamp bases they make & with the above, sometimes one calls one thing something very similar to what another calls another. For the most part however there is a standard in place in common with all.
I have been taking notes a few years now, otherwise below I will post links to likely sources for more info I have not updated my notes for in having more info. Unless that's all the company specilizes in however, it can at times be difficult to find that section of the website with lamp
base info. On the other
hand, every lamp spec from the manufacturer will have details to it's lamp
base type & most are going with the more Euro
system of metric number combined with letter code as opposed to attempting to figure out what of three types of Mog. or of like three types of
Edison, or assorted types of medium
base the old US
system used.
Letter following the
base type designates that the distance from the bottom of the collar to the bottom of the
base contact on SC or DC

“B” = As a letter following the
base type designates the distance from the bottom of the collar of the
base contact is 9/16". For

Wire lead Lamp Bases. = Heat, humidity and mechanical loads place high demands on airfield lamps, yet these lamps have to be easy to adjust and replace. Osram lamps with cable connections and cement free prefocusing bases have been designed to meet all these requirements. By moving the electrical contacts away from the lamp
base, we have been able to reduce significantly the risk of the
base or seal overheating as a result of electrical contact resistances. The prefocusing
base greatly reduces the need for adjustments by the housing manufacturer and by the end user. Overall, these features lead to improved electrical contact and excellent reliability.
