Gimbal Adjustable Tension Wire Spotlight for AR111 Lamps

I assume you sell a transformer for these? Couldn't see one on your website? I need a dimmable version
Yes we do. Product Ref: 41040 and Product Ref: 6792 (put the number in the search bar to view).

I have tension wire installed and some of the lights are in need of replacement. They don't have anything to identify the brand other than ar111 12v 35 w (on the base it says 12v20w-50w) would you be able to recommend a replacement light.
If you require a lamp head either product ref 41037 or 1769 would work for you. If you are in need of replacement bulbs product ref 3732 or 51607 should work. Bear in mind the load of the transformer, and therefore we would suggest using the same wattage of the existing lights.

Can these be set up to be dimmable?
Yes, If used with a dimmable transformer. Call us if you are unsure on which one you require.

What is the maximum cable room span for this model?
The cables under tension should be at 155mm centres for this fitting.

What size wire fits with this light 4mm our 6mm?
Over a shorter run we would recommend 4mm, over a longer run 6mm.
