The filiment in a 93 is horizontal so the majority if it will not hit the reflector properly. It would likely look better then the LED replacement though. I get wanting/needing to use LEDs for an indoor display bar. You do lose the focal point but you also wont be killing your eyes as much with that focal point.It almost looks like the LED's do not sit in the focal point of the reflector. Thus loosing that POP. I think you can convert the bulb holder easily over to a bayonet base type bulb...from what I remember. Then use the #93 bulb
I should add that I am using the #93 bulbs on a display bar. I do not overload my power supply doing so. The LED replacements can not sit in the sweet spot of a parabolic reflector but will still have some focus. Think about the Maglite. You can twist it to go from beam to flood. It is mofing the filiment of the bulb out of the focal point. It is similar with the LED replacements but they can not hit the reflector properly because the light is too wide.The filiment in a 93 is horizontal so the majority if it will not hit the reflector properly.
