What is Light Therapy & Does it Actually Work?
Here is a partial list of what one company promises sitting under a small panel of red lights will improve: athletic performance and recovery (owing to faster muscle recovery and joint repair), sleep (thanks to increased melatonin production and a “healthy circadian rhythm”), and skin quality (because of reduced inflammation and increased collagen production).
These red lights, in this case made by Joovv, are one of dozens of at-home versions of what’s known as light therapy, or photomedicine, or photobiomodulation, a technology based on the idea that light can change us on a cellular level. This past summer, the journal Frontiers in Medicine published an issue dedicated to photomedicine, and its 12 articles have an overwhelming effect similar to Joovv’s marketing copy, covering dermatological concerns like aging, skin cancer, and psoriasis as well as autoimmune diseases like type 1 diabetes. I like the way a 2016 journal article phrases it with a bad joke that gives away the researcher’s quiet exuberance: After a brief overview of peer-reviewed light-therapy treatments (for arthritis, hearing loss, and chemotherapy side effects), the conclusion states that “after decades confined to the ‘scientific wasteland,’ [photobiomodulation] may be finally emerging into the light of day (pun intended).”
It's pretty amazing what you can do with light these days, with narrow spectrum LEDs that can only produce the light you want.

A revolution is upsetting the lighting business as LED lightbulbs replace energy-hogging incandescent ones. This is good news for consumers and the environment; using less energy reduces the greenhouse gases that contribute to climate change.
But this shift comes with a cost, exemplified by a century-old lightbulb factory in St. Marys, Pa., that is the latest to shut down.
For much of its long history the LEDVANCE facility, 120 miles northeast of Pittsburgh, produced lightbulbs under the Sylvania brand. Now all it produces is scrap metal.
Times change and so do technology. The truth is the modern light-bulb is far more sophisticated then those outdated technologies, and China built the factories to make the inexpensive advanced, highly-efficent switch-mode power supplies and LED panels that make the modern bulbs much more affordable -- rather then the United States. But as technologies advance, it really is a win for most Americans, even if the old technology manufacturers are left behind.
Trump Administration Wants To Reverse An Obama-era Light Bulb Efficiency Rule – NPR
"If it's been a few years since you shopped for a light bulb you might find yourself confused. Those controversial curly-cue ones that were cutting edge not that long ago? Gone. (Or harder to find.) Thanks to a 2007 law signed by President George W. Bush, shelves these days are largely stocked with LED bulbs that look more like the traditional pear-shaped incandescent version, but use just one-fifth the energy."
"A second wave of light bulb changes was set to happen. But now the Trump administration wants to undo an Obama-era regulation designed to make a wide array of specialty light bulbs more energy efficient."
"At issue here are bulbs like decorative globes used in bathrooms, reflectors in recessed lighting, candle-shaped lights and three-way light bulbs. The Natural Resources Defense Council says that, collectively, these account for about 2.7 billion light sockets, nearly half the conventional sockets in use in the U.S."
