Four boxes and one en-light-ened monkey -[ CrAzY Tuesday ]-
National and UCAR arc carbon boxes. (The blue National box is empty; the remaining ones are full. UCAR was a newer brand, but the carbons inside were still stamped National.) Carbons like the ones in the boxes were used in lamp houses like the once ubiquitous Peerless Magnarc; until xenon-arc light sources became popular in the 1970s.
The carbons inside these boxes were regarded as the best available; backed with a longstanding support program in their day. Even though the xenon arc required less maintenance and did not require replenishment every other reel or so, enthusiasts note the carbon arc's light quality was better from a properly aligned and maintained lamphouse.
