ALamps with an aperture of 0.5 mm diameter are high brightness types. These lamps provide 1.6 times higher brightness than standard lamps with an aperture of 1.0 mm diameter. (Refer to page 8.)
BA trigger voltage higher than this value is required to start lamp discharge. For reliable lighting, an application of 500 V to 600 V is recommended. The maximum rated voltage that can be applied is 650 V.
CThe heater current during warming-up period is so high that the enough voltage may not be supplied to the lamp in case the cable between the lamp and the power supply is long because
DThe lamp life end is defined as the point when the light output falls to 50 % of its initial value or when output fluctuation (p-p) exceeds 0.05 %.
EL2D2 lamp does not always have a direct replacement for conventional type from its dimensional outline point of view. Please refer to page 5 and 6. Please consult with our sales offices
of voltage drop at the cable. The power supply for the heater should be designed so as to supply specified voltage at the lamp terminal.

NOTE
The see-through type electrode structure enables
straight-line arrangement of the halogen lamp, deuterium
lamp, optical system and optical passage. This simplifies
optical design of UV-VIS spectrophotometer etc., and
eliminates loss of light amount caused by the half mirror.

FRecommended operating voltage is 3.5 V ± 0.5 V.
GIn these lamps, discharge current is allowed to flow into the filament during operation so that cathode temperature is maintained at an optimum level. So there is no need for input of external
