[R-1051] Lamps

[Guido Santacana]

Definitely I don't know what they were thinking with these lamps. I guess my work is cut out for me during the Xmas break. Such a complicated scheme for a couple of lamps. In any case they should have thought of more durable ones. Thanks for all the answers.

This was detailed on Nolan Lee's website but I am not sure whether anyone is hosting that material anymore.  I can't remember the # of the bulb I used but I bought a quantity from a bulb specialist that has an on-line ordering system.  They were not too expensive and I ruined a couple trying to make replacements.
