EiKO 250W T-4 Projector Bulb with G6.35 Base - 8000 Lumens, 24V, High-Performance AV/STT Lighting Solution

EiKO stock code 10257: a 24 volt, 250 watt T-4 lamp on a G6.35 bi-pin base, classed by EiKO as AV/STTV - the audio-visual and stage, studio and television category. This is the kind of lamp that sits inside a projector, an overhead, a microscope illuminator or a piece of medical or lab equipment, fed from a low voltage supply rather than from a branch circuit.

Why this listing carries a warning rather than a spec sheet

We check every specification against the manufacturer before we publish it. For this one we could not. EiKO's live catalogue was read in full on 22 September 2026 - every published item - and stock code 10257 is not in it, nor is any G6.35 lamp. The specialty and AV lamp range EiKO sells online today does not include it. So the table below is our own stock record, reproduced as-is and labelled as such. If you need a certified specification for a submittal, ask us and we will chase EiKO directly rather than guess.

Specifications

Best for: replacing a low voltage bi-pin lamp in projection, stage, studio or lab equipment where the existing lamp is marked 24V 250W on a G6.35 base.

Common questions

Where do these specifications come from?
From our own stock record, not from a manufacturer datasheet. We read EiKO's live catalogue on 22 September 2026 and this order code is not published there, so we have flagged the listing rather than dress it up.

Can I run this lamp on a normal 120 volt circuit?
No. It is rated 24 volts and draws over ten amps at that voltage. It is fed by a transformer or a low voltage supply inside the equipment, and putting it across a line voltage supply will destroy it instantly.

What is a G6.35 base?
It is the two pin bi-pin base designation, where the number is the pin spacing in millimetres. Several different lamps share it at different voltages, which is exactly why you must match voltage as well as base.

Should I handle the glass with bare hands?
No. Oil from your skin bakes into the envelope on a hot running lamp and causes early failure. Use a glove or the paper sleeve the lamp ships in, and wipe it with alcohol if you touch it.
