Ushio 1000799 Halogen Bulb
The Ushio 1000799 is a 70 watt halogen bulb that operates at 24 volts and uses an H3 PK22s base. It produces 1750 lumens with a colour rendering index of 99 for accurate colour reproduction. This clear, single-ended lamp suits stage, studio or specialist equipment requiring this exact voltage and base configuration. It is not for buyers who need a mains-voltage replacement or a different base type.
Sustained Output Characteristics
Rated life is 150 hours at full 70 watt power, so output remains consistent until the filament reaches end of life. Halogen chemistry maintains lumen maintenance better than standard incandescent types during that period. The 24 volt design means voltage drops in long cable runs will reduce output noticeably. It is not for users who need thousands of hours between replacements.
Pre-Installation Checks
Verify that the fixture supplies exactly 24 volts and accepts an H3 PK22s base before ordering. Confirm the lampholder can handle 70 watts of continuous heat without insulation contact. Ensure the application can accommodate a 150-hour service interval. It is not for installations where the supply voltage or base format differs from these specifications.

Questions about this item
How much heat does the 70 W halogen bulb produce during extended use?
The 70 W halogen lamp converts most input power into heat, so the fixture and surrounding area will become very hot during continuous operation.
What voltage supply and socket type are required for the H3 PK22s base?
It requires a 24 V power source and a fixture with an H3 PK22s socket that matches the terminal base.
Will the 150 hour rated life be shorter if paired with an older transformer?
An older transformer that delivers unstable voltage can reduce the 150 hour life expectancy and may cause premature filament failure.
