The Green Force Heptastar 2000 DPM light head has seven LED’s generating 2,000 Lumens. This anodized aluminum light head is incredibly mean when it comes to power consumption, a mere 21 Watts, which translates into good burn times
The ‘DPM’ in the name refers to ‘Dynamic Power Management’. In other words the light automatically adjusts the level of illumination according to the amount of light that is required.
Close up objects do not require huge illumination, whilst objects in the distance, or during an emergency, require full illumination. It appears to be a very sturdy product and in fact Green Force states it is almost indestructible.
