Q ReflectorsStandard dome and 30°angle polyester reflectorsare shown elsewhere in thiscatalog section.

Q Rapid SmartStarterInstantly restrikes a hotHPS lamp when power isrestored after a momentaryoutage. Removes itselffrom circuit if lamp burns

out or is removed fromsocket. Available factory-installed only. To order, addsuffix -HRE to catalognumber. See page F1-20.

Q Quartz EmergencyLightWhen ordered, HPS fix-tures will be supplied witha prewired special DC bay-onet base socket to accepta 150W or 250W, 120Vquartz lamp (not furnished)that automatically switcheson when a power outageoccurs. Fixtures orderedwith this quartz emergencylamp feature do NOT com-ply with requirements forclassified areas and shouldbe used only in non-clas-sifed locations. To order,add suffix -E to catalognumber and specify if a re-lay switch is desired.
