ᐅ Looking for stair lighting and ceiling spotlights – manufacturers? Where to buy?

Hello everyone,

I am looking for LED lights.
1. Stair lights
I am searching for stair lights that are installed directly into the wall in the stairwell, approximately every two steps at a height of about 30cm (12 inches), to illuminate the stairs.
Which manufacturers would you recommend? Where can I buy these types of lights? I have found them offered on eBay, but I am unsure about their quality.

2. Ceiling downlights
In the hallway and bathrooms, I am looking for ceiling downlights.
These should also be LED spots. I have the same question as with the stair lights: which manufacturers do you recommend, or where can I easily buy them?

Thank you and best regards,
Herbert
