I am planning to install a [Ring branded video doorbell][1] at a home I am visiting for a few days.  We are struggling to find a doorbell transformer on short notice, but did find a halogen light transformer.  

It's not a perfect match of the requirement as the intended light would pull much more power than the doorbell, I'd like to know if it's likely I damage the transformer and then in turn Ring doorbell if I try this transformer or use it for a weeks until we have a better replacement.  

I also read something about halogen transformers not being suitable for LED lights due to randome wavelengths in the output frequency, and I wonder if the same is an issue for the Ring doorbell.

Requirement:
- 8-24 VAC, 10-40VA, 50/60 Hz

Specification of the transformer:
- 11.5 VAC, 4A (it would transform from 230v, 50Hz)

The transformer lists 12v 50 watt as the intended light.
