Had a lamp bought for testing purposes, then 2 more

the expectation was to get an anti-glare recessed luminaire for stairs lighting.
This was fulfilled.
Of course, I knew that no power LED were installed with the latest technology.
But it was me in this case, the light and the power consumption important.
I'll probably still buy more to incorporate this as path lighting in Kunstoffpalisaden and thus create a glare-free cost-effective solution.
