The Priolite M500 500W/s Monolight is a high performance flash head with powerful core features and wide system compatibility. The M500 uses a power supply with PFC (Power Factor Correction) that not only prevents power spikes during recycling but allows the flash head to recycle at 1.0 seconds to full power and fire six times per second at minimum power. That type of performance usually results in substantial heat buildup but Priolite has anticipated that by incorporating a highly efficient fan to protect the system's electronics, flash tube and modeling lamp. The M500's extruded aluminum alloy housing provides a rugged vessel for all of this technology while offering convenience features like an umbrella receptacle that runs the length of the head for extra support of shafts up to 10mm in diameter.
The M500's Triggering options include an optical slave and a built-in radio receiver with a remote range of up to 984' that requires separate purchase of a transmitter for use. Other conveniences include multi-voltage operation, Bowens S-type mount compatibility and a 5.0 stop power range. Note: the reflector is for illustrative purposes and not included.
Extremely Fast Recycling Time
The M500 provides an extremely short recycling time of 1 second to full power and can provide up to six flashes per second at minimum power. A powerful temperature control fan prevents overheating of the modeling lamp, flash tube and electronics. When the power level is dialed down, excess energy is dumped automatically and the current power level appears on the M500's 3-digit LED display.
When the M500 is fully recycled, not only does the test button light but a small dome on the top of the housing glows as well, making it easy to monitor it at a distance.
PFC - Sophisticated High Performance Power Supply
The Power Factor Correction (PFC) module allows the integrated high-performance power supply to provide constant current while the capacitors fill, avoiding spiking that could trip the mains supply breaker.
Bi-directional Radio Control
The built-in Bi-directional Radio Control Module operates in conjunction with the optional Priolite Radio Transmitter which mounts on your camera's hot shoe. Nearly all functions of the flash can be displayed and controlled. The transmitter displays the power settings and flash readiness of up to nine heads in four groups. The 2.4 GHz system is approved for world-wide use.
The extruded aluminum alloy construction of the M500 functions like a protective shell that houses components safely. An elongated sleeve grasps umbrellas up to 10mm in diameter along the full length of the flash head for extra stability. A special locking clamp prevents dimpling of the shaft.
Constant Light Distribution
The M500 employs a user-replaceable, omega-shaped flash tube that delivers better light distribution than U-shaped tubes.
Standard equipment includes a glass UV coated dome which provides protection and ideal color temperature.
Easy to Read Large Display
The M500 features a highly visible, easily adjusted, multi-line LCD panel that displays the head's functions and settings.
The Priolite system is compatible with Bowens S-type bayonet accessories as well as many of Hensel's reflectors.
Made in Germany
The M500 was designed, developed and manufactured in Germany under strict quality control supervision.
