| A) Costly rare gas in
each lamp promotes cooler filament operation, increases life and light output. |
| Back to top |
| B) Longer, heavier, more
expensive coiled tungsten filament is sturdier, more durable, resists shock and vibration,
burns cleaner and longer. |
| Back to top |
| C) Taller glass stem for
better support of filament - hand annealed to insure proper seal around dumet wires. |
| Back to top |
| D) Two or more feet of
extremely close tolerance tungsten alloy wire wound with proper spacing between coils in
filament to prolong filament life, improve lumen maintenance and give more average light
output over life of lamp. |
| Back to top |
| E) Each filament has 4 to
7 supports to resist shock and vibration in an industrial or commercial environment.
Tungsten filaments are chemically cleaned three times before mounting in lamp for cleaner,
brighter operation. |

| F) All impurities
(including air) are pumped and burned out of lamp for cooler operation and longer life. |
| Back to top |
| G) Brass base on all
lamps - resists corrosion and oxidation found on typical short life aluminum based bulbs
greatly reducing 'freezing' in sockets. |
