- Unfortunately, the bulbs do not fit ordinary GU4 Fittings (where previously Philips) was in it. - The unnecessary additional outer trim ring is because, unfortunately, in the way and you can not purely-click the lamp. (Design flaw) - The 2 power tiller at the bottom are too short and the lamp falls out of the socket - If you do not give the full 20 watts of light she begins to flicker. - Did the company tries to reach by phone, but unfortunately nobody decreases. There is no after-sales service.
Although the lamp super economical (90% less power) should be with LED technology, I can not recommend them anyway. Too bad that you could not before all tests (design, flicker problems) and no one is even reachable by phone.
