OSRAM EVC 64657 250 W Halogen Lamp

The OSRAM EVC 64657 is a 250 W halogen lamp operating at 24 V with a G6.35 bipin base. It delivers 9000 lumens and a colour rendering index of 100 for accurate colour reproduction. The rated lifespan is 300 hours. It is suited for fixtures that accept this specific base and voltage.

For Stage and Studio Fixtures Requiring G6.35 Base

This lamp fits professional stage, studio or medical luminaires designed for a 24 V G6.35 halogen source. Buyers needing a different voltage, base type or significantly longer service life should look at alternative lamp technologies. The 300-hour rating means frequent replacement in continuous-use applications.

Direct Plug-In Replacement for Compatible Sockets

Installation is a simple push-fit into a matching G6.35 socket; no tools are required. Ensure the fixture is rated for 250 W at 24 V and that power is off before handling. Common issues include premature failure from skin oils on the quartz envelope and voltage mismatch if the supply differs from 24 V.

Questions about this item

What voltage supply must I already have for this 24 V halogen bulb to operate?

The bulb requires a 24 V power source; connect it only to a circuit or transformer that delivers exactly 24 volts.

Can I keep my existing G6.35 bipin socket when replacing an older halogen lamp with this 250 W model?

Yes, the G6.35 bipin base matches standard sockets of that type, so the bulb fits directly without changing the holder.

How do I verify the 9000 lumen output and 100 CRI are being delivered after installation?

Switch the lamp on and confirm bright, white light with accurate colour rendering; a light meter can measure the 9000 lumen level if precise validation is needed.
