Can you explain what you mean? Is this similar to natural lighting somehow?

  Photographers like their lighting to be as close to natural as possible for best pictures. They can tell the effect when taking pictures, they have measuring tools to understand the light before taking pictures, and they have equipment (bulbs, panels, etc) made to satisfy their use cases which they can actually evaluate for quality. Light quality is generally measured in CRI (color rendering index), with 100 being sunlight. Best professional photo lights give you up to 97 CRI. I don't know how closely CRI reflects the biological effect of the sun light, but we sort of can judge it by proxy - CRI reflects photography requirements, which correlates with closeness to sun light spectrum, which correlates with biologically positive effects. Even being a proxy, this measuring ability is still vastly better anything we have for the "health" light which you can't really measure except in a control group study which none of us can do. In practice I suggest going to Amazon and shopping for high-CRI lights, such as photography LED panels, about $100-$200 a pop. They're not big enough to light up a room, but they can light up your desk or maybe cubicle. I bought a few and the light is very, very pleasant. Alternatively shop for high-CRI CFL lights to replace the ceiling lights, those can light up the room. I haven't tried that yet though. It might also be useful to buy a CRI meter so that you know where you stand. Expensive as they are, might be still worth it considering the benefits. Also maybe pool money with friends on this - you're not going to use it a whole lot.
