8 GU10 50W mains voltage halogen bulbs (Spacey Houses HG3)

8 GU10 50W mains voltage halogen bulbs. 3 Crompton, 1 Philips. Found in a box in the garage. No idea if they work or where they came from. In original packaging, but one box slightly damaged. Since taking the photo I've found another 4 bulbs so 8 in total.
