Halogen lamp for medical and scientific use

The Ushio 8000353 is a 235 watt halogen bulb operating at 33 volts with a GY9.5 bipin base. It is built for microscopes, ophthalmic instruments, microfilm readers and projectors where a compact, high-output source is required. The lamp delivers 1000 hours of rated life in a small envelope suited to precision fixtures.

Replaces OSRAM 58941 and GE 11548 cross-references

This model serves as a direct substitute for the listed OSRAM and GE part numbers in existing equipment. The jump is worth it when the original lamp reaches its 1000 hour rating and output drops below the level needed for clinical or scientific observation. Matching the 33 volt supply and GY9.5 base ensures drop-in compatibility without fixture changes.

235 watt output with 1000 hour rated life

At 235 watts the lamp provides intense illumination for high-magnification microscopy and projector applications. Headroom is limited to the rated 1000 hours; beyond that, colour stability and intensity degrade, affecting diagnostic accuracy. The compact bipin design fits tight optical paths but offers no margin for voltage variation above the specified 33 volts.

Questions about this item

Will the GY9.5 base fit my fixture?

The GY9.5 bipin base has a 9.5 mm pin spacing and is designed for sockets that accept this standard.

How do I install the bulb without shortening its life?

Handle the quartz envelope only with clean gloves or a cloth; skin oils create hot spots that can cause premature failure.

When should I plan to replace this 235 W halogen lamp?

The average rated life is 1000 hours; schedule replacement before that limit to maintain consistent output in medical or projector use.
