CONVENTIONAL LAMP

CONVENTIONAL TECHNOLOGY
Crystalization of fused silica
envelope has occured after 500
hours or so operation, which will
reduce the light transmission.

UNIQUE “DOUBLE HALOGEN CYCLE” TECHNIQUE

Outer gas convection suppresses the thermal reaction
with the fused silica envelope thus protect it from
crystallization. It maintains the envelope strength and
light transmission even after 500 hours of operation.
Inner gas convection assures the metal halogen cycle
which minimize the electrode dissipation.
