What a beautie this is! I had never seen a SBMV lamp before, let alone a westie! This gets very hot. The arc tube doesn't really put out anymore light than the filament, only the color shifts to a whiter color and makes fluorescent-colored objects stand out.
The date code is "3 3", the same as a westie 100w cleartop i had gotten from him back in July.
Thanks guys! Cool to know you have one too Dave. Do these typically run really hot? What wattage is the filament and the arc tube separetly? This seems to put out around the same amount as a 200W incandescent.
Yep thats 3/83 for this lamp, but 3/73 for that cleartop. SBMVs do get very hot because you have both the filament and arc tube. I think generally 2/3 of the energy goes to the filament, the rest goes to the arc tube.
Codes run on a certain cycle, it may be 8 years, 10 years, etc. Every manufacturer is different, they have their own secret ways. Codes are used for warranty reasons. BTW, yes you can use it in any position.
