The lamp is a bit unstable, which is not covered by installation but more significant. The lamp is really minimalist, it could not be less. it's good. Only drawback was against that of three ordered lamps had a faulty contact and logically did not shine. That I was able to fix it yourself. However Really bad is the luminosity of the supplied Omnilux UV tube. For I have an old Sylvania UV tube for direct comparison, whose luminosity is significantly higher - (!) At least felt three to four times higher - for the same wattage.
At my request to exchange it said of Voelkner succinctly: "We have not the opportunity to offer the requested tube and not an option".
The Sylvania UV tubes there seems to be on the market only as discontinued models at inflated prices. There are reportedly also a Philips UV tube, but I can not even try.
