This is a really good one for all-purpose light.
I was looking for something that's bright enough for working but not so strong when reading.
This is it.
I put it in the middle of my working table and reading chair. When working, pull the light to the working table to adjust to 100% cool light.
When reading, reduce it to 50% warm light. When doing something else, lift it up and 100% mix light. The best part of it, move the light to the right place which makes you really comfortable! Make sure light source always comes from right direction!
