Or 2000K wide spectrum LED lamps vs doing stupid 6000K-5000K LED lamps at night and messing with human sleep cycles even more :/ Or causing nausea with the narrow spectrum yellow sodium lamps.

the problem with 2000k lights is that human night vision is much more sensitive to bluer light. you can use about half as much light while appearing as bright by moving to 3500k
