OSRAM EVD 64663 400W Halogen Lamp

This OSRAM EVD 64663 halogen lamp delivers 16000 lumens at 400 watts and 36 volts. It uses a G6.35 bipin base and is rated for 50 hours of life. The clear finish and high colour rendering index of 100 suit stage, studio and projection applications. It is not for buyers who need long-life general lighting or low-voltage LED replacements.

Installation and Common Issues

The G6.35 bipin base pushes into a matching socket without tools. Handle the quartz envelope only with clean gloves to avoid oil contamination that causes hot spots. The lamp measures 2.34 inches long and 0.59 inches in diameter; verify fixture clearance before fitting. It is not for fixtures that cannot dissipate the heat of a 400 watt halogen source.

Sustained Load Behaviour

At full power the lamp maintains its 16000 lumen output and 100 CRI throughout the 50 hour rated life. The compact MR16 envelope runs very hot; adequate airflow in the fixture is essential to prevent premature failure. It is not for continuous duty cycles that exceed the rated 50 hour envelope without scheduled replacement.

Questions about this item

How can I confirm the 16,000 lumen output is correct after installing the 400W 36V G6.35 halogen bulb?

The bulb should emit a very bright, clear white light immediately on power-up; a noticeable drop in brightness or a yellow tint indicates it is not reaching the rated 16,000 lumens.

What comes with the OSRAM EVD 64663 HLX bulb and do I need a separate G6.35 bipin socket?

The package contains only the single MR16 halogen bulb with its G6.35 bipin base; a compatible 36V fixture or socket must be supplied separately.

Should I choose the 400W 36V version or a different wattage for my MR16 fixture?

Select this 400W 36V model only if your fixture is rated for exactly 36 volts and can handle 400 watts; otherwise choose a bulb matching your fixture's voltage and maximum wattage.
