I have 20 of these NEW (Open Box) ORACLE LIGHTING 2 foot by 4 foot recessed LED troffer light. It currently sells in the marketplace for $172. These are all 35K (3500K) light, which is a nice soft pleasing light. They also have a nice reflecting light box with lens to nicely diffuse the light, unlike many other cheap LED lights that are either "integrated LED panels" or a thin structure that reflects the light from the middle out to the sides and down, with no lens. They are 4000 lumens, and dimmable.
