Ok, so the fittings are appropriate for installation environment.
Find the W/m2.k for chipboard.
Look up online what the formula is for passive heat absorption.
The answer will indicate whether the existing volume is large enough.
Dependent on limiting temperature you may need to use high temperature cable.
Selection of a dimmer unit will need to take into account maximum load, 8 x 50 w. tbh 4 x 50w would be adequate for this space. Look around, you may be able to get a unit with a switched bypass for a fixed load.
