One of the tempered glass UV shields in my MH/T5 lamps shattered a couple of days ago. I’ve taken it out of service until I can get some tempered glass cut to size.
It got me wondering though about whether these lamps produce as much UV towards the end of their lifetime as when they’re new. I know the visible light spectrum shifts towards longer wavelengths as the lamp ages.
So do they still produce UV, especially UVC, in the same amounts they did at the beginning of their lifespan? My lamps will need to be replaced within the next 6 months or so. I can see a small amount of black soot in all three lamps.
I’m not running that particular lamp and thankfully I don’t have any corals under that particular lamp although a BTA recently moved to a spot under it. Would it be too risky still to run it? I assume so which is why I took it out of service. It’s a 250w plusrite lamp.
