Multi-Coloured Bauble Explosion Chandelier

I bought this light fitting a couple of years ago and it had suddenly stopped working. It can’t be the bulbs as they are all completely out at once and the mains hasn’t tripped. Is there a transformer somewhere inside that can be replaced? Thanks
Yes, there is a transformer in the ceiling rose, similar if not identical transformers are available from a variety of sources.

How close to the ceiling could it be mounted? ie how short is it safe to make the cord?
There is no limit to how close the lights are to the ceiling beside the diameter of the sphere itself (60cm), but it will start to loose its effect if mounted too close.

What is the actual height of the chandelier? The glass part. Could you put it in a bathroom?
The glass balls slide onto rods fanning out from a central point. The diameter and height is 60cm. This product could be used in a well ventilated bathroom if mounted outside of zone 2.

roughly how big is the light?
This measures 600mm in diameter so 60cm. The suspension (flex) is max 1300mm, 1.3m.

Is this light dimmable?
Yes, when used with a dimmable lamp. The included lamps are non-dimmable.

Please could you let me know what weight this is?
This fitting weighs 4.2 kg.
