"Great little wall light with a few niggles. The quality of finish is excellent. The amount of room inside to make off connections is tight to say the least. The aluminium acts as a heat shunt so if you run 50W Halogens in these the case will be hot enough to burn you after just a few mins. Even with heat sleeve over standard BS6004 T&E 70C max the T&E sheath (not the sleeve) has started to melted so I guess these build up heat above the rated 70C.
I would purchase again but my recommendation would be to ONLY fit LED GU10's so as to keep the heat down.
