I've read conflicting reports on what danger there is to breaking a flurescent bulb/tube. I was trying to kill a fly which found its way into my basement seed starting area/lights, and knocked a 34/40 watt tube out of the shop light setup onto the table about 12 inches down. I put it back in and it still works....so that means it didn't break at all right? No mercury release?

I also read something about if the ends of the tubes are capped in green, that they are ultra low mercury containing lights (which mine are)....is that true for all tubes? Any advice?

Thanks!
