I misspoke, 2700k is not a cure all (but it usually reduces the blue). Lower than that makes the light too yellow (a candle is 2000k). BUT there are apparently blue-free led's with higher temperature, more white light.
This should be sorted out before buying all these LED's or we may see a doubling of prostate and breast cancer if the areas in the article above are any indication. This is no joke.
