Spanner with gauge
Some use To adjust mixing tube part 33 on all 500CP, 350CP and 250CP lamps. The New BriteLyt XL do not need to adjust just raise as high as you can part 33.
Use Spanner for a rule adjust higher then the spanner (the higher the better on BriteLyt lamps)
Used for removing nipple(part# 50) with center hole in the spanner, and good for removing part #111 hand wheel (On and Off knob)on all size lamps.
