Do I need a constant current or voltage power supply to drive 12V Halogen lights?

My apologies for this basic question. I need to replace a 12V power supply to drive 2x 20W halogen lights.

I found this power supply that would meet my space requirements (height):

This one states "constant voltage". Will this work if I wire halogen lights in parallel?

If the bulbs are filament type halogen lamps, the a constant voltage supply will work fine with the lamps in parallel.

Led driver not made for Halogen lights which do not require either constant voltage or constant current.
Halogen lights are a thing of the past, wayyyyy too much heat dissipation.
It might work though, as they say , suck it and see.
Can only cook itself.

I'd be buying a couple of LED lights which, complete, and plug straight into mains supply, would be less than what you intend to pay for the LED driver.
