I keep hearing about new super lumens torches to be realised soon and why are they all running on one 18650 .I actually use my headtorch to work on the beach in complete darkness for 3hrs at a time and its no fun trying to change a battery full of sand or raining .
Even with 3500mah batteries they dot last long on full power.
