50 W 22.8 V Halogen Replacement

This 50 watt halogen bulb operates at 22.8 volts and uses a G6.35 two-pin base. It produces 1000 lumens with a colour rendering index of 100. The T4 shape suits projectors, microfilm readers, microscopes and studio fixtures. Rated life is 1300 hours.

Replaces SM-H2000 64650 Types

It directly replaces bulbs marked SM-H2000 or 64650 with the same wattage, voltage and base. The upgrade is worthwhile when the existing lamp has dimmed or failed and accurate colour rendering is required. Do not use it in sockets rated for different voltages or wattages.

Check Fixture Voltage and Base

Verify that your equipment supplies 22.8 volts and accepts a G6.35 two-pin base before ordering. Confirm the physical space accommodates a T4 envelope. Using the wrong voltage will destroy the bulb instantly.

Questions about this item

Will the G6.35 2-pin base with 6.35 mm pin spacing fit my fixture?

Yes, the bulb uses a standard G6.35 bi-pin base with 6.35 mm pin spacing, matching any socket built for that base type.

Is there a specific orientation or handling step required when installing this halogen bulb?

Handle the quartz envelope only with gloves or a clean cloth; skin oils create hot spots that shorten the 1300-hour rated life.

How often should I plan to replace this bulb under typical use?

The lamp is rated for 1300 hours; at four hours per day that equals roughly one replacement per year.
