OL4 Solar Hazard Marker

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.

Benefits

  • Self-contained in a durable, rugged enclosure
  • No specialized work crews required: simple to install and relocate
  • User-friendly design: onboard interface offers easy configuration and programming
  • Low maintenance: replaceable battery pack with life expectancy of 5 years
  • Tested at the toughest industrial standards
  • Light environmental footprint with natural solar charging, recyclable batteries, and RoHS compliant design

See a Case Study

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

Models and Options

Color Output
The OL4 is available in various color configurations depending on your application. Check the specification sheet to see the intensity settings for each color option (note: peak intensity is dependent on your location and your selected flash pattern).
OL4 with ON/OFF switch
The OL4 with an ON/OFF switch option lets you easily turn the light on and off when needed. When the switch is in the ON position, the light will charge during the day and turn on at night. When the switch is in the OFF position, the light will still charge but won't turn on at night.
OL4 without ON/OFF switch
The OL4 without an ON/OFF switch is preprogrammed to turn on at night—simply mount the light where you need it and it will automatically charge during the day and turn on at nightfall.
GPS Control
Ideal for tower and crane applications or projects where you need the lights to flash at the same time, the OL4 GPS control option syncs multiple equipped lights to flash in unison.
