A few months ago I purchased the Wuben H1 LED Headlamp after seeing it on special in this Ozbargain post https://www.ozbargain.com.au/node/692172. I needed a headlamp for gardening after dark and the occasional camping trip.
At first I was really pleased, it was exactly what I needed. However, after using it on the 1200 lumens setting for 2 hours one time, it ran out of charge. I recharged it, making sure it was fully charged. Again, after using it only on the 1200 lumens setting, it died after 2 hours, leaving me in the dark, which was quite disappointing.
I know nothing about batteries (except that they come in little, medium and fat), and the battery in here looks to me like a AA on growth hormones. The information says it's an 18650, 3.7V 2600mAh rechargeable lithium battery, and the battery itself is unbranded. I googled it but all I found were lots of similar looking unbranded ones, and one branded 'Jugee' which I've never heard of, but no information about how long they should last or which was better.
Is 2 hours normal for one of these batteries on 1200 lumens, or is there a better battery I could buy? Am I being unreasonable to expect it to last longer? Is there another headlamp better suited to my needs? If this is normal and I need to keep multiple batteries on hand, can anyone recommend a good charger (keeping in mind I'd like to use it for camping)?
Thanks for shedding some light on this for me.
Yes this is normal. The run time at max brightness isn't usually super long.
That being said, why are you using it at max for so long? You can get another 18650 if you require using it longer than that at max brightness.
The Littokala range is cheap and good.
