who after a test with three spotlights in the kitchen in exchange for 20W halogen recessed spotlights was very positive, we have replaced the remaining radiators there.
The light output is superior to the previous installation clear when not even 3W / lamp, have actually verified that times, was even slightly less than 3W.
Since only 58mm holes were present, failure are the usual Recessed spotlight with GU10 base, but here you get a completely finished recessed spotlights, something is in the nature / quality not in the usual DIY stores have.
Visually, they are making a high-quality impression when installed.
If the shelf life is now given on time (the time will tell) would be the top, until then I would recommend them without reservation.
