Been looking at lights. LED's are starting to move further on the scene. Sylvania ultra hd bulbs exist. Others exist too. http://en.wikipedia.org/wiki/High_CRI_LED_Lighting
CREE, manufacturer, is pushing the quality too.http://www.cree.com/news-and-events/cree-news/press-releases/2013/january/crtrofferseries
Professional cinema led lights coming, ie., http://hexolux.com/cinewhite/
Even Mole Richardson is moving in the LED direction.http://www.youtube.com/watch?v=9vllvIGTVlM&feature=player_embedded
In the next few months, it should get very interesting.
