Something most folks overlook with LED lighting - color rendering index, or CRI. Most LEDs are 80 CRI or so, which causes colors to be "off". Higher priced LEDs are 90+ CRI - and if they are they will indicate so on the packaging. High CRI is one of the things that make Ott lamps the choice for most crafters.
My sewing room has all slimline flush mount 4000K (color temperature) 90+ CRI fixtures.
