The specifications of this product are according to:
• Low intensity obstacle (group B) (CAA)

Low intensity obstacle lights are used where the object height above the surrounding ground is less than 148 feet (45 m). This product is explosion proof and can be used in zone 1 and zone 2 areas.

An omni-directional low intensity steady red obstruction light is fitted to the highest point of the installation. The light conforms to the specifications for a low intensity obstacle light having a minimum intensity of 50 cd for angles of elevation between 0° and 15°, and a minimum intensity of 200 cd between 5° and 8°. Where it is not practicable to fit a light to the highest point of the installation (e.g. on top of flare towers), the light is fitted as near to the extremity as possible.

Our low intensity 200 cd lights should be used on obstacles located away from the movement area or on the movement area with high levels of background illuminance.
