If a mercury discharge lamp then you will have a hard time finding a
resistance.
You have to check there is a standing voltage and a trigger pulse

I suspect the OP is referring to something like the following.

LED Projection Lamp Lights for Architectural Lighting (QL-P2-W):

I believe a DMM would see the LED strings as open circuits.
