low and medium intensity solar obstruction lighting for met towers

Carmanah LED lights ensure your meteorological testing (MET) towers are clearly visible. Our solutions for MET towers are quick to install, cost-effective, and reliable. Easily programmable, our lights offer options including continuous flash patterns and infrared modes, making them suitable for a variety of military and civilian applications.

State Legislation

Many US states have included lighting—as either a requirement or recommendation—in their legislation for marking MET towers. This is to enhance the presence of towers for agriculture and other low-level aviation operations.

How We Help Our Customers

As Central America’s leading wind energy company, Globeleq Mesoamerica Energy (GME) develops, constructs, and operates wind energy projects across Costa Rica, Honduras, and Nicaragua. They sought lighting for five meteorological masts, installed in May 2016 in Costa Rica.

For project engineer Sebastián Zeledón Castro, choosing Carmanah’s solar lights was an easy decision. Before working for GME, he had worked for a company that installed and maintained meteorological masts for wind resource assessment purposes; since this company was also a regional dealer of Carmanah products, he became familiar with Carmanah’s obstruction lights.

“Carmanah products have proven to be the optimal obstruction light device throughout almost six years now that I’ve been using them. The self-contained feature and easy setup are, in my opinion, two of the most important characteristics of this equipment.”
– Sebastián Zeledón Castro

MET Tower Lighting Products

The OL4 and OL800 are portable solar LED lights that offer an ideal solution for rural locations away from the electrical grid. Since they require no external wiring, they are easy to move for temporary projects; the OL4’s optional magnetic mounting kit makes redeployment even easier, but these low-intensity lights can also be used for permanent installations. Meanwhile, the OL800 offers remote monitoring via GSM and Globalstar satellite networks, allowing secure one- or two-way data transmission that comes in handy especially for hard-to-access installations.

The OL371 is a medium-intensity red obstruction light suitable for FAA type A0/A1 structures. For structures between 200′ and 700′ AGL (FAA E-type towers), the OL370d medium-intensity dual (red and white) obstruction light is available. Both solutions are appropriate for permanent installations via AC power and provide MET towers with reliable, durable, long-lasting obstruction lighting. Both also meet Transport Canada CAR621 regulations.
