We have lighting power available to said Inglenook fireplace via 1.5mm2
switched T&E from downstairs lighting circuit.

This used to feed a pair of incandescents via two surface mmount BC
pendant battens.... on the wood mantelpiece beam.

The BC battens have cracked in the heat and require replacement and
SWMBO would like a remote controlled colour changing system like:

What colour changing lighting systems can I consider that will not have
their lifetime shortened by the heat within said inglenook fireplace?
