<p>The invention relates to an UV lamp (100) that may for example be used as a torch for crime inspection. The UV lamp (100) comprises a light source (50), e.g. an UV LED, and a reflector (30) which are designed such that a light spot comprising an inner region of a given minimal diameter D at an axial distance of about 8-D is produced which has an intensity variation of less than about 20 %. The reflector (30) may preferably be a Compound Parabolic Concentrator (CPC) with a high aspect ratio. Moreover, the UV lamp (100) may comprise a luminescent indicator for making activity of the UV lamp visible to a user.</p>
