There has been a move to integral lamps where there are no user replaceable parts, and there is also a kick back where is seems firms who do things like using glue or potting compound in the future are likely to be surcharged by the EU to try to stop this trend.
As to torx drive screws in the main they are used to stop screw drivers slipping and only when there is a pin in centre are they considered tamper proof.
We have GX53, MR16 and MR11 lamps at 75mm, 50mm and 35mm and many different ways with the multifaceted reflector types like MR16 (16/8th inch so 2 inch or 50mm) with G5.3, GU10, SES etc of connecting the light bulb.
This has produced problems with DC and AC and 10-30 volt, 12 volt, 110 volt, 120 volt and 230 volt and to make a lamp which has everything integral has some benefits.
The MR16 lamp with a G5.3 two pin connector comes as DC, AC 50Hz, fixed 12 volt, and 10 to 30 volt able to dim and not able to dim, also 24, 48, and 110 volt versions, and adverts often don't even state the voltage, and so you have AC 50Hz lamps being run from DC power supplies, and also AC power supplies in the kHz range which can make them into mini transmitters.
So there is a good reason to move away from interchangeable light bulbs. I think it likely you need to change whole unit.
