FlashGuard 3000

FlashGuard® 3000B

The Flashguard® 3000B Medium Intensity Dual Lighting System combines a daytime white strobe light and a nighttime red flashing strobe into a single flashhead, eliminating the need for two separate lighting systems. 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 and night intensities by the use of a calibrated photocell. Flashguard® 3000B flashheads incorporate a light blocking strip that minimizes ground scatter light, resulting in a “community friendly” lighting system.

FAA Type: L-864 and L-865 Medium Intensity Lighting

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 red flashing beacon at night provides a “community friendly” light. Hughey & Phillips’ 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. This light is compatible with Enhanced Flight Vision Systems that use IR energy emissions for imaging, including NVG goggles.
