Our office has to purchase replacement UV lamps for our air filtration system. The manufacturer recommended lamps are fluorescent and contain a low level of Hg (3 Mg). So my question is, would we have to include these lamps in our purchasing plan? They are not being used to light a space, the main purpose of these lamps is to disinfect air filters. If the UV lamps need to be included, I was able to get the Hg content from the manufacturer and the lamp life (it's recommended to replace the lamps every 2 years) but I can't find anything on lumen output. How would one go about calculating the picogram per lumen if there is no lumen value available?

I can see the arguement both ways for this. It's a grey area. UV light is still light and can fit the intent of this Credit's scope. But it's also integral to a piece of equipment that serves a function other than lighting. No one is asking for mercury content in other lighting integral to equipment like the light in your refrigerator or microwave.
I'd say use your own opinion and you can find justification either way if challenged.
