Osram 64664 HLX halogen bulb 400 W G6.35 14500 lm 150 h

The Osram 64664 HLX halogen bulb is a 400 W lamp with a G6.35 cap, delivering 14,500 lm of luminous flux and a rated lifetime of 150 hours. The HLX version uses xenon as filler gas, which allows a higher light output at the same power consumption and is designed for professional and stage lighting where stable, high-intensity illumination is required. The lamp has a beam angle of 105° and is suitable for fixtures that accept a G6.35 halogen capsule.

Advantages

Xenon-filled HLX variants provide up to 10% higher luminous flux compared with krypton-filled equivalents while maintaining the same power consumption. The 400 W power rating and 14,500 lm output deliver strong, consistent light suitable for demanding applications. The standardized G6.35 fitting ensures compatibility with equipment designed for halogen capsules of this type.
