Fail-Safe designed the HUD Series with a vertical burn lamp and 
symmetrical distribution in wattages up to 175W MH as an unbreakable 
replacement answer to commercial fixtures which might succumb to 
vandalism. A corrosion resistant cast aluminum housing holds a 
polycarbonate diffuser which fastens with four tamper resistant screws to 
prevent unauthorized access. Double gasketing seals out the environment. 
The HUD Series is specifically designed for use in public access areas where 
vandalism may occur. Ideal for building perimeters, parking structures, 
corridors, stairwells, schools and dormitories.

injection molded, impact resistant, 
prismatic polycarbonate refractor 
for high efficiency, low surface 
brightness and maximum strength.

prevent unauthorized access.
Heavy duty, corrosion resistant 
cast aluminum housing withstands 
impact and environmental abuse.
