iSSL® Series All-in-One Solar Lighting System

iSSL® is the world’s most reliable all-in-one solar lighting solution and the result of 10 years of research and development.
All the products in the iSSL® range offer unrivaled performance, thanks to its high-density NiMH battery technology and patented energy management system (EMS) that ensure optimal efficiency throughout the year.

Fully plug & play, the installation of a lamp post has never been as simple and quick as with the iSSL® range. Available in three sizes, iSSL® is a solar-powered lighting solution perfectly suited for parks, pathways, parking lots, and general area applications.

iSSL® is the only all-in-one solar light to offer multiple lighting optics combined with custom lighting profile programming, allowing the product to be tailored to each of your projects.



  • 10-years warranty: As a testament to its quality, the iSSL series is the all-in-one solar light with the longest warranty on the market.
  • Anti-blackout feature: the iSSL® features proprietary adaptive lighting algorithms that adjust the light flow automatically to ensure proper lighting throughout the night, all year long.
  • Theft-proof: Components are placed within the housing, at the top of the pole, to prevent theft. The mounting bracket cannot be removed from the pole without appropriate equipment (theft-prevention kits are available on request).
  • Reduced installation time: Thanks to its plug & play design, it only takes 20 minutes to install a light, pole included. There are no special skills needed. Reduced time to install = reduced project cost.
  • Built to resist even the most severe weather: Because of its unique battery technology and patented passive cooling system, the iSSL® series will operate consistently whether in the middle of the desert or surrounded by ice and snow.
  • The only integrated solar light that can be air-shipped: The iSSL® has been designed to be deployed quickly, anywhere around the world. It doesn’t use materials classified as dangerous goods by the FAA and can therefore be shipped by air.
  • Incredible reliability: 100% of our systems are tested before they leave the factory. Our latest calculations show a 0.5% failure rate, based on the 25,000 units deployed since 2015. In the rare case of product failure, a complete replacement is provided to minimize downtime and impact on users.
