______________ Great question!

What separates Wolff from the “pack” is our high-grade phosphor, which produces consistent results, beautiful color and long lamp life. Also, we’ve been standing behind our sunlamps for 28 years – you cannot be in business that long if you make an inferior product.

The phosphor coating on the inside of the glass tube is the source of a sunlamp’s tanning power. Just as there are many roads to Rome, there are many phosphor blend combinations that give similar spectral results, but not all individual phosphor components are created equal. The best choice should be the phosphor that has the highest purity, the highest efficiency (UV output per watt of power consumption), the slowest natural depreciation (decline in UV output over time), and the highest reliability in the manufacturing environment. This is accomplished by using high-grade phosphors.

Different phosphor blends produce different results and different UV wavelengths: UVB is from 280-320 nanometers, UVA2 is from 320-340, and UVA1 is from 340-400nm. UVB stimulates melanin production and can burn the skin if overexposed; UVA2 acts a lot like UVB, with melanin production and some pigment darkening; it is also closely associated with elastosis (photoaging, wrinkles). UVA1 penetrates deeper past the surface of the skin and is primarily responsible for pigment darkening. Newer lamps are being designed to focus on providing enough UVB to stimulate the melanin and aid in production of vitamin D, plenty of UVA1, and less UVA2.

Besides the best phosphor blends, quality assurance is of utmost importance. When you purchase a Wolff System sunlamp, you are buying a product that has passed stringent quality control assessments. Once in production, Wolff System sunlamps undergo multiple quality inspections every step of the way; any deviations from standard are identified before the lamps complete the production cycle. All lamps are subjected to post-production quality hold, where once again the lamps are tested before shipping. A small quantity of each run is held back from shipping for thorough evaluation and life testing. Our ever-expanding volume of performance data constantly updates and refines the standards for each lamp type.

For 28 years, Wolff System has been proud to produce lamps that reliably tan your customers. If you should ever have a quality question, contact our licensees or distributors, call us directly at 800.959.6533, or visit www.wolffsystem.com.
