I got a pair of Phillips Green ACE block IR, UV, and sodium flare. Shade 5.0
But after putting up 6 or 7 lights in my work area I only ever use them when I pull cane or know in advance I'll be using the outer flame on my GTT Mirage. They are too dark for me to do any detail work even with all of the extra lighting.
Most of the time I use shade 3 diddys & a flip up magnifier head apparatus
and Blast Shield's IR filter glass shield because I have personally known more than one lampworker who have gotten skin cancer on their face which no amount of eye protection can help with.
