This high-efficiency, compact lantern is suitable for use in most solar locations. The M850 is over 30% more efficient than previous generation lanterns and is capable of an average 3 to 6 NM range with the ability to reach over 7 NM. Multiple battery pack options (60 or 96 A/Hr) provide customers the ability to cost-optimize their purchase by selecting the best solution for their installation location.
The M850 combines a compact, high-efficiency solar engine with premium components and a rugged design for best-in-class performance at an optimal price. This small format lantern delivers up to 445 cd (IALA peak, white) and can achieve up to 7.5 NM range at T=0.74.
