Abstract: A radiation source assembly comprises a source base, a UV transparent sleeve, and a UV lamp. The source base comprises a sealed electrical connection interface and an opposing sealed sleeve interface. The sealed electrical connection interface comprises a electrical contacts and the sealed sleeve interface comprise a radial sealing element, an outer collar, and a compression ring. The UV transparent sleeve is engaged with the sleeve interface such that the radial sealing element of the sealed sleeve interface is disposed between the UV transparent sleeve and the outer collar of the source base, and the compression ring is positioned over the UV transparent sleeve and engaged with the source base to compress the radial sealing element onto the UV transparent sleeve and the outer collar. The UV lamp is disposed within the UV transparent sleeve and electrically coupled to the electrical contacts of the electrical connection interface.

Abstract: An embodiment provides method for controlling lamp output within an array of lamps, including: receiving sensor data corresponding to one of a plurality of lamps within the array, wherein the sensor data comprises an irradiance value from at least one of: within a lamp sleeve and an irradiance value from outside a lamp sleeve; identifying, based the sensor data, a change in an output of the one of the plurality of lamps; sharing the sensor data with other of the plurality of lamps within the array; and adjusting, in response to the sharing, an output of at least one of the other of the plurality of lamps within the array, thereby compensating for the change in the output of one of the plurality of lamps. Other aspects are described and claimed.
