Reply to comment by eliteLord77 in Black and Hispanic hairdressers are exposed to a complex mixture of chemicals, many of them unknown, potentially hazardous, and undisclosed on product labels, researchers report. There are more than 700,000 hairdressers in the United States, more than 90% of whom are estimated to be women. by MistWeaver80

Those UV leds are cheap 400nm ones. That could be considered visible light. I mean it IS visible light.

You can cure the nail polish in the same 120 seconds by going out around noon in summer.

Soo unless you are avoiding the summer sun that much; LEDs won‘t make a difference.

The problem isn‘t UV LEDs it’s using 50W UV lamps where all of that energy is in the UV spectrum.

Rather than an LED lamp running on a 5V 2A USB supply..
