Please note that my university education is in engineering and I have no particular knowledge of lighting or lighting design. That being said, I hope that my input is at least slightly useful as it is coming from more of a consumer's perspective.
After browsing the various brand options, I decided that my favorite was the brand K.B. Form. Aesthetically speaking, their designs are quite sleek, but still unassuming and minimalist. This, to me, means they are more likely to integrate nicely into a pre-existing living room or bedroom setup. Many of their designs are simple rectangular lamps with square or rounded corners. These are likely to be more accessible to customers with little experience in interior design (such as myself). I imagine it unlikely that their products would mesh poorly with a given interior, compared to the more bold lighting brands on your site such as Next Lighting.
The selling point for K.B. Form (to me) was their floor lamps, which are either height-adjustable or directional. When I say directional, I mean that the light is purposefully projected only in one direction. Examples of this are the Bastobianco 50 floor lamp and Bastocolore 70/4 floor lamp on your website. This is a fantastic feature which I see is missing from a lot of the other brands.
Obviously, lighting is needed most in the evenings and at night time. However, it is now very well documented that excessive exposure to lighting late at night can disrupt the body's natural sleep cycle. In particular, exposure to the blue wavelengths of light inhibit the body's ability to produce melatonin, a sleep-inducing hormone. Since learning about this several years ago, I have made several adjustments to my computer and lighting habits, and made great leaps in my sleep quality. After sunset, I now aim to keep my lights as soft and low to the ground as possible, while still being able to work and operate comfortably. I also actively avoid looking directly at light sources near bed time, and I have my lights cycle on and off on a timer. All of these things are features which are enabled by K.B. Form's floor lamps. The directional floor lamps mean that I can turn them on and off without having to hurt my eyes by looking straight at them. I love the idea of facing them against a wall so that they provide just enough lighting at night time.
Thus, I think the products of K.B. Form are highly functional for those late-night workers like myself. I also think their sleek and unassuming designs will fit well with a large number of interiors.
