In the parent article, the author talks about obtaining replacement bulbs - Since this is an arc lamp, there's no filament to burn out.
Does anyone know the failure modes of an arc lamp? Do the electrodes wear out / erode? Is repair even possible for something like this or is it essentially remanufacturing the entire thing because of the capsule enclosing everything?
- excesslumens 6y agoUnfortunately not repairable. Failure modes: cathode melts, gap gets larger, unstable arc; anode melts or cracks, possible catastrophic failure; seals (uranium glass) to tungsten leak, xenon bleeds out; envelope fractures, catastrophic failure! In some cases electrodes vaporize and plate the inside of the envelope. Details at https://www.sqpuv.com/PDFs/TroubleshootingGuide.pdf https://www.sqpuv.com/PDFs/TroubleshootingGuide.pdf
