The 6 Best Vitamin D Lights
This wiki has been updated 11 times since it was first published in November of 2018. Among the extremely rare home remedies that actually show clinical effectiveness, UVB phototherapy can be a life-changing treatment for those with chronic conditions like psoriasis, vitiligo, and vitamin D deficiency. An appropriate wavelength near 311 nanometers allows these lights to provide safe, evidence-based healing, so long as they're used in compliance with your doctor's instructions.

In this update we removed the Elited Handheld and the Yonker Portable due to availability concerns. We added the Veingram Narrowband, a particularly portable option similar to the Yonker Portable which can be used as a handheld device or planted on a stand for hands-free use. We also added the Rayminder M260, a very powerful option similar to the Rayminder Midband that runs quietly so that you don't have to worry about bothering people when you use it.
There are many devices on the market that claim to function as Vitamin D lamps but don't emit UVB light, which is a requirement for triggering vitamin D production in your skin. On this list, we've only included items that do emit UVB radiation, but it's always a good idea to read product descriptions carefully to ensure that the light you're thinking of purchasing does what you think it does. As these devices are intended to treat diagnosed medical conditions like eczema and psoriasis, you should also consult a medical professional before using them.
Note that while these devices do tan your skin, they're not intended to be used for this purpose as they're quite powerful and can easily burn you. Because they emit UVB radiation, they're also not a good remedy for Seasonal Affective Disorder or major depression; if you're looking for a light that could help combat either of these mood disorders, check out our list of the best therapy lamps, most of which utilize UV-free LEDs that don't run the risk of burning you or adversely affecting your health.

This is an interesting class of products, because they're relatively inexpensive solutions to a range of difficult conditions to treat, and they actually work. The rarity of that is impossible to understate: these things can really work wonders on a number of pesky, itchy, painful, and unsightly conditions. The most effective focus on the 311-312-nanometer wavelength, which won't burn the skin nearly as quickly as higher-frequency UVA light. They CAN absolutely burn you, however, if you use them too long. Also, you'll notice that they cause a delayed tanning effect, only releasing tannins in the skin after a few days of regular, moderate use. Additionally, a surprising number of medications, both over-the-counter and prescription, can make your skin overly sensitive to any UV rays. That includes common skin treatments like coal tar, many prescription meds from your doctor, as well as some narcotics. The top Sperti model can be found as the subject of a number of studies, many of which you'll find on PubMed. The best smaller option is the DermaHealer, and it's roughly half the price of the relatively huge Spertis. No matter which you choose, use it 100% in accordance with the instructions of a qualified doctor, preferably a dermatologist.
