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.
