The Aurora AU-GUF4011/30 11 Watt Warm White PAR20 Lamp is a rather specific lamp designed for use with SGU10 Lampholders only. Note that they have a longer body than the standard style.
“Our property has these ceiling lights in every room. They are quite efficient but tricky to find as cannot be bought in any usual stores like Homebase etc. and they are quite expensive.”
