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'
