The Sun-Tech Triangle Billboard Light is a professional off-grid solution for signage and billboards. Triangle Billboard Lights provide downward illumination with no glare effect. The CHAM branded Li-ion & LiFePO4 battery has a long lifetime of over 2,000 recycle times (more than 5 years), and the digital LCD battery display makes it easy to see the percentage of charge.

An additional port for an extra solar panel can be added to this billboard light at an extra cost.
