More than 400 independent clinical studies have proven that the UVB Narrowband TL lamps are safer and more effective than any other lamps in their class. These lamps emit UV radiation in the ‘B’ bandwidth of the UV spectrum (290 to 315nm) and are therefore suitable for phototherapy systems designed to treat skin diseases.

UVB Narrowband TL – proven as the most effective in phototherapy
-Minimum side effects like redness, itching and burns
-Shorter period of exposure and less erythemal radiation than conventional UVB lamps
-Optimal therapeutic effect with minimum side effects
-Proven to be most effective on the skin

More than 400 independent clinical studies have proven that the UVB Narrowband TL lamps are safer and more effective than any other lamps in their class. That is because these lamps emit only a very narrow waveband from the ‘B’ bandwidth of the UV spectrum (290 to 315). This narrow waveband is between 305 and 315 nm and peaks at 311 nm: the most efficacious waveband for the treatment of psoriasis. This means that treatment is much more focused and exposure times are much shorter. This in turn leads to a reduction of side effects such as reddening of the skin and itching. All of this makes them ideal for phototherapy treatment of diseases such as psoriasis, parapsoriasis, vitiligo, atopic dermatitis, and mycosis fungoides. What’s more, because the overall dosage of this narrowband radiation can be closely controlled, these lamps are suitable for home therapy.

Good Narrowband UVB light
This lamp is a great product of Philips, for the users who need narrowband emission of UVB light. There are other alternatives, more broadband that include also UVA, but this is one of the few solutions available in general. Unfortunately this product is discontinued from Philips but was able to find a stock, so query the availability and place the order without risks here.

Nowadays the preferred radiotherapy treatment of skin diseases like psoriasis is through the use of the ‘B’ bandwidth of the UV spectrum, since this requires no photo-sensitizing agent. But some patients do not respond to UVB treatment, hence a UV lamp with an ‘A’ bandwidth of the UV spectrum is used, and here Philips offers a choice of either a...
