By chance I came across the offer for Aqua recessed spotlights with IP44.
Then the supplied cardboard boxes emerged after opening very high-quality processed massive recessed spotlights in a brushed stainless steel finish incl. Precisely fitting GU10 sockets. The downlights had before my absolute benevolence.
If the hole is prepared for installation, the recessed spotlights can by clamping of two steel springs are inserted into the introduced to the receiving opening in the ceiling. The springs grab while a strong and keep the spotlight with its rubber seal splashproof in the opening.
A change of the light source can be achieved by disconnecting the entire installation from the radiator opening. Since the springs are very strong, which is not an easy task. Fortunately, the recessed spotlights have even a screw. Opening the exchange of bulbs is thus easier to implement. For this to work, the scope of the built radiator must however be firmly locked in the opening, as otherwise turns the entire recessed spotlights in the opening during rotation. That was no problem for me, because the ceiling panels was newly introduced and a rigid mounting in the opening was so easy to implement.
I was rewarded with the fact that the possibly necessary change of lamps can be easily achieved by moving up and screwing. I've been with IP44 can ever find in any other recessed spotlights.
Summary:
I am completely satisfied. A buy recommendation from me.
