It has a 5 minute timer and the instructions say to use it twice a week maximum, unless directed to do otherwise by a doctor. It has four flourescent tubes tuned to optimally emit UVB for vitamin D creation. It comes with safety goggles that have to be worn when using it. You have to stay 17" away from the lamp when it is on. Sperti says it is the only FDA approved vitamin D lamp in the USA.
It's expensive but apparently the only one of its kind at the moment, until the UVB LED's take over the market.
That is the cheaper alternative. In my experience, it's probably fake, as the FDA requires prescriptions for legitimate phototherapy devices sold in the US.
You can find the same type of devices on eBay and Alibaba for even cheaper, but those are the same "quality".
