Powermax TU-PMHTU500
The Powermax 500W Halogen Tube serves as a high-output light source for heavy-duty floodlighting applications. This linear lamp utilizes a halogen gas cycle to maintain high luminous efficacy over its operating lifespan. It features a standard double-ended R7s connection interface. The quartz glass construction allows the unit to operate at high temperatures without structural degradation. This component provides a color temperature typically ranging between 2900K and 3000K. It integrates into outdoor security luminaires and indoor work lights. The internal filament design supports horizontal burning positions for optimal heat dissipation. Additionally, the quartz envelope provides basic UV protection for the internal components.
Key Features
-
Standard R7s Interface
This double-ended base ensures a secure electrical connection within compatible spring-loaded lamp holders. -
Halogen Cycle Technology
- Prevents tungsten evaporation from darkening the glass envelope.
- Extends the operational life of the filament compared to standard incandescent lamps.
- Maintains consistent lumen output throughout the service life.
-
High-Grade Quartz Construction
The heavy-duty glass resists thermal shock and maintains structural integrity under extreme operating temperatures. -
Dimmable Performance
The resistive tungsten filament allows for precise light level control using standard phase-cut dimming systems.
Technical Performance
Industrial environments require reliable lighting solutions that provide immediate full brightness. The TU-PMHTU500 reaches peak intensity instantly upon power application. This characteristic makes the unit suitable for motion-activated security sensors. The 118mm form factor represents the industry standard for 500W linear lighting components. Procurement managers should verify the physical dimensions of the fixture housing before installation. However, the horizontal orientation of the tube remains critical for ensuring even heat distribution across the filament supports. Proper alignment prevents premature failure caused by gravity-induced filament sagging. Technicians must use lint-free gloves during the installation process. Skin oils left on the quartz glass create localized hotspots. These hotspots cause the glass to devitrify and eventually fail. This lamp operates efficiently on 220-240V AC circuits without the need for external ballasts or transformers. The high wattage rating provides a wide beam spread when paired with high-polish aluminum reflectors. This combination effectively illuminates large construction sites or warehouse loading docks.

Bought this for my outdoor security floodlight. The brightness is very good for 500W, really lights up the gate area well. Just be careful when fixing it not to touch the glass with bare hands so it lasts. Good value compared to what I found in the local hardware shops.

Received the tube in good condition and it fits my floodlight housing perfectly. Very bright for the price.
