The OL4 is a light-weight, high-performance hazard marker with superior solar energy management. Designed for tough industrial locations such as mines and constructions zones, the OL4 is ideal for marking ground-hazards, fences, barricades and other construction hazards on site.
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
