I am looking to replace some 12v 20w mr16 bulbs in my kitchen with 5w led ones
from what I have read I think I have a wire wound one so I should be ok ? it is very heavy. The transformer is running 3 x 20w mr16s in the ceiling now.
These are the ones that I am looking at getting http://www.screwfix.com/p/lap-mr16-led-lamp-gu5-3-346lm-5w-cool-white-pack-of-5/2454g
But another question is - are the screwfix ones AC or DC or both, the spec only says "truefit Replacement for 35W Halogen", on one of the Q&A someone has replied with this
I wasn't sure but tested one across a 11.1v lipo battery and it worked connected in either polarity suggesting they have a bridge rectifier inside. Connected to a 12v AC transformer and after 5 min it is warm to touch (NOT hot like halogen) and working.
So I thought that I would ask the proper experts here
Here is a picture of my transformer (which is the same as the one in the ceiling )
