What\'s the dot?
Please excuse my ignorance, but I'm wondering what the "dot" is that's on some of the SF led heads I've seen.
For e.g., I have an older KL1 kead and it has a white dot about 4-5 mm in dia (and appears to be a self adhesive sticker) stuck on the outer flange of the bezel.
I have also seen photos of other SF led heads with a similar (only green) dot.
I assume it's some kind of coding system, but can anyone explain the code to me?
TIA for any info you guys can provide me.
