Where does this article mention LED lights vs other types of artificial light-at-night? What I could find regarding light color:

> However, most studies relied on satellite-images with a very low resolution (1 to 5 km, from the Defense Meteorological Program [DMSP]) and without information on color of light

> noted that data quality suffered from many limitations due to the types of satellite images used and the focus in the vast majority on visual light levels only rather than considering the circadian-relevant blue light component, among others. Future studies should consider improved satellite-based ALAN technologies with improved resolution and information on spectral bands and apply these technologies to a variety of cancer sites to yield better estimates for the potential risks between ALAN and cancer.

So nothing conclusive about LED being bad for your health (vs other types of light).

Looks to me that _you_ conclude it's related to LED, I couldn't find that stated in the abstract, it might just be related to a general increase of artificial lightening, regardless of the source.
