вот первый совет от незнакомца ...
You might want to look into converting it to LED... Same brightness with only about 7 watts... Lasts a lot longer and produces much less heat too... There have been posts in this group about converting to LED so maybe try a search or maybe someone who sees this can shed some light on it

this one is UV lamp, I am not sure have anybody ever tried to use LED for such installation. UV LEDs are also not simple thing , I guess. I have converted my Nicon from halogen lamp to LED , pretty good results ... but Fluorescence ... Hmm, I need full range from 400nm to 500nm excitation to use existing filter sets, LEDs are very narrow.. But yes I can try to limit it to 450 for only GFP work, but anyway new power supply is needed ... after all, new lamp costs 100 euro..
I really wonder for a hacking idea, how to prolong that Mercury lamp lifetime even at expense of less quality. Maybe it can work much longer them normally if I adjust something, let's say, place a small fan for extra cooling. The only problem - it can explode and contaminate room with mercury, but how much of that mercury is inside? 100 mg or 300 mg .. not that big deal. If compare with all the other chemicals around, just a tiny extra fraction of health damage.

If it explodes, the explosion itself will be the worst effect. Please note, that it can do it also when off and cold. ALWAYS wear protective glasses when handling short arc discharge lamps, whether mercury or xenon based.

Vladimir Kaigorodov to Wojtek Plonka .. You mean wear glasses during installation of new lamp? Good notice . I agree. It is in a solid metal box, that protects microscope operator from explosion . I hope . They do not ask to wear protective glasses with fluorescent microscope in operation .. It is safe enough without any extra protection measure. Indeed, those lamps can explode, and it is expected event.
