UVC lamps of the TUV type have their main radiation at a wavelength of 253.7 nm. These transducers are manufactured by our trade partner – the company Philips – and is converted with a 4-pin-base and a cap in our firm (s. picture 1 and graph). The consequential advantage is a single sided electric connection. TUV lamps consist of a special glass which avoids the ozone generation. The transducers with a cross section of 15 mm are available in two different lengths. The short bases reduce the length for 25 mm.
