They may indeed figure it out but side by side, LED suffers from a narrow range of frequencies, which results in hard edges and monotone glare. So I have tested and rejected it in places where I am trying to create warm atmosphere. I use it for masked accent lighting and kinetic purposes.
If you need to take a leak in the bush, put your LED lamp on, you might see 5 meters if your lucky before your view is lost in some indeterminate fuzz cloud. If you want to see if there is a bear 50 meters away making noise, grab an old school 6 volt lamp that will send a concentrated beam to low lying clouds.
LOOK before you JUMP, collectively, we are losing this capacity.
Wikipedia has some interesting things pro and con. Here are some con, because they just don't seem to be on anyone's radar screen..

Health concerns about LED streetlights[edit]
• Exposure to the light of white LED bulbs suppresses melatonin by up to five times more than exposure to the light of pressure sodium bulbs.[4] The fact that white light, emitting at wavelengths of 400-500 nanometers suppresses the production of melatonin produced by the pineal gland is known. The effect is disruption of a human being’s biological clock resulting in poor sleeping and rest periods.[5]
• Research at the University of Madrid Complutense University[6] has claimed that long term exposure to LED Street-lighting can cause irreparable harm to the retina of the human eye. The Madrid study said this was caused by the high level of radiation in the’’blue band’’[7][8]
• Artificial night-time lighting has various effects on humans (not to mention wildlife) and that exposure to optical radiation affects human physiology and behavior, both directly and indirectly. Many areas are not well understood, and a position statement from the Illumination Engineering Society (IES) emphasizes mainly the need for further research.[9]
• There is a main risk from glare. A French Government report published in 2013 agreed that a luminance level higher than 10,000 cd/m2 causes visual discomfort whatever the position of the lighting unit in the field of vision. As the emission surfaces of LEDs are highly concentrated point sources, the luminance of each individual source can be 1000 times higher than the discomfort level. The level of direct radiation from this type of source can therefore easily exceed the level of visual discomfort[10]
