LED lighting will soon be the only lighting used in these United States. There will be some other types of lights but generally all lighting old and new will be led. This huge changeover will be a "Lighting Rush" while we change our billions of bulbs and tube lights in a few years time.
From a Rayleich lighting broshure
The most common light in America in 2013 was the 4 foot fluorescent tube. These will all be replaced by led tube lights or complete new fixtures.
Tube light has achieved another 33% reduction in energy for the same amount of light. One year ago the standard 4ft tube used 18watts. The new tube uses 12 watts readily available in May2016.
Also a tube is on the market that will operate with or without a ballast.
