In addition the ceiling of the carhad been freshly painted a dead presenting more favorable conditionsfor the bare lamps than would generallybe obtained in service. Further, the glareeffect obtained from hare lamps is suchas to render the eye much less efficient aswell as susceptible to severe eye strainthan where reflectors are used.
