Getting the Most Out of Your Obstruction Light

In our standard recommendation process, we'll suggest a cost-effective solution that meets the most common user requirements, provides good intensity and has suitable energy storage to perform reliably at your installation location. Many of our obstruction lights also come with value-added features that can enhance the overall performance of your lighting system.

FAA/ICAO Compliant Intensities: If you are trying to achieve a specific red aviation obstruction lighting standard as set by ICAO or the FAA, Carmanah can help. Currently, our solar powered obstruction lighting is best suited for low intensity L-810 and ICAO Type A/B lighting and some medium intensity applicatons. For medium intensity lighting, please contact our sales team at for assistance.

GPS Flash Synchronization: This feature is available with a subset of our lights. It is particularly useful in aviation obstruction applications and in way-finding applications where sychronizing flashing along a path will help increase visibility for approaching traffic. This feature is currently only available on request with our OL800 products and should be used with the flash pattern feature described below.

External Chargeport: Carmanah lights are designed to re-charge fully each day through the natural power of the sun. However, in the event that you will be storing your lights indoors for lengthy periods, an external chargeport may be a useful feature. This option will allow you to connect your light to an AC charger to top up the battery prior to deployment. All connectors are located in the base of the product and have a sealed port to prevent water ingress.

Autonomy & Sizing: The number of days your product can run, independent of charging, is referred to as its "autonomy." Typically an autonomy of 7 days is recommended (imagine 7 days without sun!); however some specifications require more or less autonomy depending on the specifying authority, the product location and local weather conditions. Requesting more autonomy may increase the overall product size and cost as, in general, a largery battery and more panel will be required.

Flash Pattern: In most applications, a standard steady-on setting will be desirable. Our OL800 lights can also be programmed to a number of distinct flash patterns. Flashing can be a valuable feature to further improve visibility or even to give a solar product extra power in a difficult location (flashing lights draw less energy than one that is illuminated 100% of the time). In obstruction applications, flashing has also been proven to reduce the negative impacts of tower lighting on birds and bats and is gradually becoming a standard recommendation in many locations.
