The Sealite SL-15 1–2NM+ compact LED light is exceptional value and incorporates
some of the most advanced technology available. In the tradition of Sealite lanterns,
the SL-15 is designed to be maintenance-free and have a service life of over 5 years.
The SL-15 can be installed in minutes and requires no operator intervention. The SL-15 has a rotary
switch to allow users to change the flash character of the light without the need for special tools or
programmers.
During daylight hours the solar module will charge the battery, and the lantern will automatically
begin operation at dusk – once the ambient light threshold drops sufficiently.
The SL-15 features Sealite's Single LED Optic which boasts exceptional power to light output
efficiency. The tough outer polycarbonate lens incorporates an environment-friendly spike –
deterring unwelcome bird life.
The internally housed battery is user-replaceable after years of reliable service.
The unit is sealed using advanced UV-sealing, enabling a rugged and complete waterproof seal
capable of prolonged and deep immersion (IP68).

Optional ON/OFF Switch
The SL-15 is also available with an optional ON/OFF switch for temporary installations such as
worksites. Please note the printed circuit board also has an ON/OFF switch as standard. This is used
for switching off lanterns placed in storage.
