Ushio 1000890 Halogen Bulb for Specialised Fixtures

The Ushio 1000890 JCD100V-650WL is a 650 watt, 100 volt halogen lamp with a bi-pin base. It produces a 3200K colour temperature suited to residential lamps, desk lamps, hanging lights, microscopes, medical and ophthalmic devices, microfilm readers, projectors and effect lighting. Its compact single-ended design fits fixtures requiring this specific form factor. Buyers needing a different wattage, voltage or base type should select another model.

Sustained Output Over 150 Hour Rated Life

The lamp is rated for 150 hours of operation at its full 650 watt output. Halogen technology maintains consistent light output and colour temperature throughout the rated lifespan rather than fading quickly in early use. The filament operates at a stable temperature during continuous runs typical for projectors, microscopes or medical lighting. Users planning longer continuous sessions should note the finite 150 hour rating and keep a spare available.

Thermal Characteristics and Power Draw

At 650 watts and 100 volts the bulb draws significant current and generates high surface temperatures during normal operation. Fixtures must provide adequate ventilation and use sockets rated for this wattage to prevent overheating. The quartz envelope becomes extremely hot within minutes and remains so until switched off. Allow full cooling before handling or replacement to avoid burns and oil contamination that shortens lamp life.

Questions about this item

How much heat and power draw should I expect when running the 650 W halogen bulb continuously?

The lamp draws 650 watts at 100 volts and converts nearly all of that energy into heat, so the fixture and surrounding area will become very hot during extended use.

What fixture or socket do I need to install this JCD100V-650WL bulb?

It requires a bi-pin base socket rated for 100 volts and able to handle 650 watts; the fixture must also withstand the high operating temperature of a halogen capsule.

Will the 3200 K output match the colour of older halogen lamps I already have?

Yes, 3200 K is the standard warm-white tone of traditional halogen lighting, so it will blend with existing halogen fixtures of the same colour temperature.
