Default Re: Mercury Arc Rectifier - How...

Interesting to note that Sefton Council assisted with disposal (perhaps the same is true of other areas....and you don't find this out until you 'phone them.)

I can understand being cautious around UV emissions of any sort and limiting exposure. I should imagine increasing the distance between yourself and the source reduces the exposure by three-quarters. (correct me if i'm wrong)

Even the BLB T8 tubes i have are unpleasant to briefly glance at, at close range. If you have old glass bottles containing trace Manganese it is possible to turn them pink or purple if you bathe them in UV for long enough. (I hope this doesn't qualify as Steampunking..)

I commented elsewhere that a rectifier bulb with a failed seal will emit red spectra due to infiltration of atmospheric gases. (Visible through a red filter.)
