Researchers have looked into driver discomfort caused by energy efficient lights, to improve driver safety:

The researchers found that the interaction between the LED luminance and the solid angle, which can be characterized by the amount of light hitting an observer's eyes (known as vertical luminescence) was the most significant factor affecting discomfort glare. To minimize discomfort, they recommend minimizing both the amount of light hitting at the eyes and the luminescence contrast between the streetlights and the background, which can be accomplished through good optical design of the LED light unit and careful placement of each streetlight.

    I predict that the study will, after much intellectual masturbation, recommend a solution which is conveniently provided by the people who paid for the study.

      For some reason, the link to the press release isn't in the summary (I thought I had add it), but that lists a funder if there is one, although doesn't list one here:

      http://www.eurekalert.org/pub_releases/2014-07/tos-ids071814.php [eurekalert.org]

      The paper is open access and does say:

      This work is funded by Philips Research China and supported by the National Basic Research Program of China (973 Program No.2010CB734102) and by the Ministry of Science and Technology of China (Project No.2009GJC00008).

        In case anyone didn't know, Philips [philipslumileds.com] is arguably #1 in LED R&D and manufacturing in the world (Cree of South Korea being a very close second).
