Red low intensity obstruction lights are usually used for tall structures less than 45m above ground level as top lights. For structures over 45m, multiple low intensity obstruction lights are used on intermediate levels to mark the structure’s outline along with medium intensity obstruction lights.
Medium intensity obstruction lights are usually used for tall structures more than 45m above ground level. According to ICAO obstacle lighting standard (Edition July 2018), There are three types of medium intensity obstruction lights: red flashing 2,000cd±25%, red steady 2,000cd±25%, white flashing 20,000cd±25% at day, 2,000cd±25% at night.

There are many cases that solar obstruction lights are perfect alternatives to electric obstruction light, for example, remote areas where electricity is not accessible.
As global solar irradiance and solar power generation potential vary upon different latitudes and climates, different sizes of PV-battery system deployed on obstruction lights are needed to meet different intensity type and operation modes with a certain amount of autonomy. REDDOT supplies the best solar obstruction lighting solutions to adapt to different geolocations: from compact PV-battery fully integrated PL10-PL32 and FS810 series, OLS10/32 semi-detached low intensity solar obstruction lights to FS864 fully-detached medium intensity solar obstruction lights.

The control box for obstruction lights is a significant device in some circumstances. Not only can a control box centrally control functions (e.g.: steady/flashing, service+service/service+standby, photosensing, bypass, etc) of obstruction lights connected to it, but also it allows users to monitor obstruction lights’ operation status and receive alarm notifications if any failure.
REDDOT provides thorough controlling solutions of low and medium intensity obstruction lights for various tall structures: telecommunication towers, buildings, tower cranes, wind turbines, chimneys, etc. REDDOT control boxes enable users to control obstruction lights’ operation.
