Our lamps are optimized for efficiency. LEDs, converter electronics, batteries, optical and thermal concept, even the cabling is fine-tuned to get the maximum amount of light from one battery charge. When not running on full power all the time, one 4-cell battery pack can last for days. Boost mode? For a few minutes? - Not with a Scurion®! Our lamps have a very effective heatsink and temparature control - Just use them on full power when you want and as long as you want!
