WHAT MAKES A GUARANTEED LONG LIFE BRAND INCANDESCENT LAMP BURN 12,000 HOURS? 


 
Costly rare gas in each lamp helps cooler filament operation, increase life and light output
  Longer, heavier, more expensive coiled tungsten filament is sturdier, more durable, resists shock and vibration, burns cleaner and longer - less lamp blackening
  Each filament has FIVE (5) supports to resist shock and vibration
  Tungsten filaments are chemically cleaned three times before mounted in lamp for cleaner, brighter operation
  All impurities (including air) are pumped and burned out of lamp - for cooler operation - longer life
  Greater spacing between coils in filament keep temperature cooler, prolongs filament life, improves lumen maintenance - more average light output over life of lamp
  All lamps are checked on light up test, held 24 hours, and 100% rechecked for perfect operation to eliminate any premature failures
  Stem of specially selected, more costly glass for maximum life, hand-annealed to prevent any air leakage into lamp
  Plus BRASS base on all lamps - resists corrosion never 'freezes' in socket
