Overview

Light where it’s needed most, all without mains power.

Designed to make public spaces safer and more accessible, the 3iS-M50 is a modular, solar-powered LED lighting system offering maintenance-free, vandal-resistant, and energy-efficient lighting for shelters and canopies. Its separate panel design allows light to be strategically placed in sheltered and covered areas where it’s needed most – all without mains power. With a compact design that enables easy installation, the 3iS-M50 provides a cost-effective solution for various applications, including public realm, education and rail.

Case study

Transforming Luton’s bus shelters

Partnering with contractor Volker Highways, we provided over 160 customised solar-powered 3iS-M50 to fit the mechanical construction of Luton’s two-bay bus shelters. The solution provided reliable illumination without the need for grid connections, reducing installation and maintenance costs while ensuring long-term durability.

FAQ

Questions

Does the 3iS-M50 need a mains connection?

No. It is a 100% off-grid solution with zero running costs: a 50W solar panel charges the system, so there is no trenching or cabling.

How long does it run through winter?

Example winter autonomy is 9 days at 3W. Contact us for a calculation on your scheme.

Will it fit our existing shelters?

Universal mounting brackets and a 3-metre cable are included. For special projects, we can design custom mounting brackets to suit your canopy or shelter.

How vandal-resistant is it?

The LED fixture body is 316 stainless steel with tamper-proof stainless steel fixings, and the lens is double-laminated safety glass. The wind rating is up to 198mph.
