I've recently switched my light fittings to GU10 so these lamps no longer fit. Master is the top of the range from Philips with the best colour rendering and longest life expectancy. Beam is 24 degrees (24D) Were working fine when I took them out and have a life of 20 yrs but that is probably based on 8 hrs per day for that period which of course they never were. They are about 5 tears old. I used these with LV halogen lighting (with transformers - which I'm also selling!) and they dimmed fine etc.. See my feedback for reassurance about my integrity Any questions please ask and thanks for reading
