Wolff System Velocity sunlamps are among the most popular choices for original equipment from ETS and as replacement lamps for other Wolff lamps, as well as those from other makers. These 100W non-reflector sunlamps employ advanced phosphor technology to assure tanners of strong color and effective melanogenesis. Rated service life of 1000 hours makes Velocity an excellent value decision. Velocity sunlamps have the quality and service life features of the Velocity family, with enhanced UVB for shorter sessions and upgrades to your existing line-up without compromising the robust UVA you expect.
