FlashGuard™ 2000B System

The FlashGuard 2000B Medium Intensity White Lighting System combines a daytime white strobe light and a nighttime white flashing light into a single flashhead. The system is also available as a red flashhead which can be used at night in place of red incandescent lighting, for much longer light source life. The flashhead is powered and controlled by a power supply that can be mounted remotely at the base of the structure. The power supply constantly monitors the operation of the system, and provides alarm contact closure upon any failure.

The system automatically switches between day, twilight, and night intensities by the use of a calibrated photocell. FlashGuard 2000B flashheads incorporate a light blocking strip that minimizes ground scatter light, resulting in a community friendly lighting system.


Medium Intensity obstruction lighting systems are typically used on structures between 150' (45M) and 500' (150M) above ground level to provide aviation safety. The use of a medium intensity white strobe during the daytime typically eliminates the need to paint the structure with aviation orange and white stripes. The use of a white flashing strobe at night provides an 'eye catching' light for low flying aviators.

Medium intensity obstruction lights are designed for lighting tall structures such as communication, television and radio towers, chimneys, cooling towers, tall buildings, catenary river crossings and bridges.
