Specialty 21 V Halogen Lamp

The Ushio 1000306 EKE is a 150 W MR16 halogen bulb built for professional equipment that requires a 21 V supply. It delivers a 3250 K colour temperature and a colour rendering index of 100. Typical applications include scientific instruments, medical devices, microscopes and optical inspection systems. This lamp is not intended for residential or general-purpose lighting.

Verify Voltage And Socket Compatibility

Before ordering, confirm that your equipment specifies a 21 V, 150 W MR16 halogen source. The lamp is rated for approximately 200 hours of service life under correct operating conditions. Using it in fixtures designed for other voltages or wattages will cause immediate failure or safety hazards. Check the device manual for the exact lamp code and electrical requirements.

MR16 Bi-Pin Base For Precision Mounting

The MR16 form factor uses a two-pin base that seats securely in compatible sockets, maintaining filament alignment for optical systems. Halogen construction provides consistent output throughout the rated life when operated at the specified voltage. Handle the quartz envelope with clean gloves to avoid contamination that can shorten the 200-hour lifespan. The lamp is supplied new in manufacturer packaging.

Questions about this item

Does the Ushio 1000306 EKE halogen bulb come with any fixtures or cables, or must they be purchased separately?

The bulb is supplied as a single MR16 lamp. No fixture, cable or transformer is included; the equipment it fits already provides the 21 V socket and power supply.

The listing shows 150 W and 21 V — are there other wattage or voltage versions of this EKE lamp I should consider instead?

This EKE designation is defined as 150 W at 21 V. Different wattages or voltages carry different ANSI codes, so the EKE itself has no alternative versions to choose from.

What does the 200-hour rating mean when the lamp is running inside a microscope or inspection system?

At the rated 21 V and 150 W the lamp averages 200 hours before failure. Voltage fluctuations or frequent switching will shorten that life, while steady operation in a calibrated instrument will achieve it.
