RE.
8 spots......Low/High voltage, Halogen/LED, Dimmable/Non Dimmable, Plastic/Metal/Brass/Chrome/Brushed, Standard/Remote switched, Surface/Recessed ? Broad price spectrum X 8
34 Sockets......Single/Double, Switched/Non Switched, Indicated/Non Indicated, Plastic/Metal/Brass/Chrome/Brushed ? Broad price spectrum X 34
12 Pendants.....If metal sockets are used I would assume you would have matching switches. Some dimmable (LED being dearer), again quite a broad price spectrum X 12 (?).
Immersion timer, Instant electric shower, central heating power valves, loo vents, extraction fans, smoke/CO detectors etc. ?
