Canned lights tend to produce hot pools of light don't they? IMHO thats not very good for safelight conditions. I opted for indirect lighting for my safelight by bouncing it off the white ceiling tiles creating a very even but not overly bright safelight level. This allows seeing down to the floor, under things, etc. that a harsh shadowy light will not allow. I have a direct beehive over the developing tray as well.
