The Feb. 5 Maine Sunday Telegram Source section included a Sea Change column by Marina Schauffler about concerns with the use of LED lighting and concerns about blue light in different environments.

What the column did not say is that most LED lights sold for home use are rated at 2700 Kelvin, or equal to the old incandescent lights – the same warm lighting rather than harsh bluish light. So you can get high-efficiency LED bulbs that are suitable for general home use. Just read the bulb packaging and look for a 2700 Kelvin rating.
