Appreciate the reply. I lamp on my own, I don’t get to speak to people about these technicalities! I’ve never had any problems once the chase is on with this lamp, my only issue is the eyes shining. Instead of buying a filter, I’ve just ordered a red led torch off amazon for the same price. It comes with a pressure switch, so I’m going to rig it up on the lamp so I have a red torch to scan for eyes, then flick the tracer on when the dogs slipped.
