These downlights have a very good quality, and I consider they have a very good value for the cost I paid (9,58 pounds).
They are much better than those than you can buy in other big shops as generic or OEM for about 15 pounds. I feel these Massive lights will last for years, with metal and solid plastic parts, not like other brands.
The emited light is very good, with a throw spot beam as it's suposse to be. Bulbs are halogen Philips 50W, and they are top quality... but you can upgrade buying GU10 leds bulbs which have better power consumption (about 3W only).
So, I recomend them so much, If you're thinking of buying downlighs then buy these!
