Typically with one of my kitchen lights on to provide some side lighting without glare. I have a fixture that hovers directly over my BK2K, but if I turn it on it's glare city.
My BK2K doesn't really like the dark, the yellow/orange/red backglass produces too much glare with the Cointaker cool supers. Might swap those out for softer warms someday. However, my Getaway with Cointakers can be played in pitch black
