AC driven vs DC driven. The 'quality' of light that is supplied from a DC power source is superior to that from a rectified AC source. Cheap rectifiers are the scourge and cancer of this lighting tech. While not discounting the affect of the blue light + phosphor even 'cheap' LED's provide a better light output when DC driven. Note: I can see/sense LED flicker (florescent tubes [or ballasts] nearing their end-of-life, and CFL's too.) So I am very sensitive to it. I also LOVE super-bright high kelvin 'cool/cold' 6500K+ lights in my home. My wife complains that it's like being in an operating room. I wonder how much of the blue-light dislike/distrust is based on a biological leaning towards a preference to carbon-rich fire/flame orange-hue's. i.e. a campfire or candle vs incandescent light vs halogen vs florescent vs LEDs on a scale of like to hate.

Blue/white fluorescent or LED lights drive me crazy in a home setting. If I could replace the one in my apartment’s kitchen I would. Their brightness is fine but their coldness keeps me on edge somehow.

  It really is interesting how light affects us like that. I suffer from a congenital cornea disease and am slowly going blind until I get a transplant. I've often wondered if that's how/why I like the lights the way I do. They always feel "cheery" to me. It brightens my mood.

  From my research and experience the operating room effect is largely due to bad color rendering with most (cheap) LEDs. Good artwork/video/photo lighting with LEDs is very expensive and bought from specialized shops or the manufacturer, but it's the closest I've found to true sunlight. If you'd like recommendations I like the Yugi strips.
