Choice of two lighting levels:
a) Low light 40 Lumens
b) Very low light 8 Lumens
– Red Led
Maintains effectively night vision, ideal for emergencies and safety warnings
Three levels of illumination :
a) Low illumination 5 Lumens
b) High illumination 15 Lumens
c) Slow flashing 15 Lumens

09.  One 4000mAh Ultra Large Capacity 18650 Li-ion Battery Included
The HC65 UHE is the industry's first flashlight to feature a 4000mAh 18650 Li-ion battery that provides approximately 17.6% more capacity than standard Li-ion batteries 3,400mAh on the market, offering extended performance throughout the night.
– Medium intensity 100 Lumens ————–> Duration 31 hours
– High intensity 400 Lumens —————-> Duration 14 hours
