GUIDE FOR STREET LIGHTING OPTICS

ver. 1.1 / 2020 AROUND WHY LEDiL? 50 The world is full of different roads and strict street lighting requirements. Add BEAMS FOR to this different LED package preferences and mechanical size limitations and possible combinations multiply exponentially. That is why LEDiL offers so many STREETS specific light distributions for road lighting to help you meet these requirements. Whether it is a tunnel in Europe or road in Brazil, we offer solutions for virtually any LED model and type; from tiny CSPs to large COBs, while keeping the optics as future proof and modular as we can, so you can keep it simple and flexible. EXTENSIVE FREE FORM CUSTOMER DESIGNS SUPPORT Make our optics the heart of LIGHT your luminaire to optimize cost, efficacy and light distribution THAT IS with great results! RIGHT
