OL4 Models & Options

The OL4 is available in various colour configurations depending on your application. Check the specifications to see the intensity settings for each colour option. Peak intensity is dependent on your location and 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 preprogramed 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.
