Question: Hi! How long does it run with 1 Alkaline AA battery? Thank you!!
Document: Amazing little flashlight. With one single AA battery it gives out a ton of light. I was really surprised. It is sturdy and it seems that it will last for a long time. This Cree LED is nothing like regular LEDs. It's much brighter for sure!
LED lights have really advanced both in terms of brightness and in affordability. I am surprised at the brightness of the Hausbell LED light. As a focused beam it can be seen for hundreds of feet. As a flood light it can completely fill up a medium sized room.Notes-- Use 1 AA Battery - which is not included- Variable angled beam by extending and retracting the lens- Very bright - especially for the size - the flashlight is about the size of a tube of chapstick.
It runs for a little over 20 min at full brightness, and then steps down to a lower brightness, and will run for a while at that. Using a AA battery, you don't get as bright light for sure.This is good for small tasks where you need bright light for short periods.
I ran one continuously with a new AA battery and got good brightness for 1.5 hours and acceptable for another half hour. I left the flashlight on and it still produced a dim light for another 5 hours when I got tired of waiting for it to go dark. The flashlight is good for around the house as it is small and bright enough. Also would be useful to light a path at night with the wide beam focus.
For the price this combo is a steal! Purchased with the UltraFire 14500 battery/charger combo. The battery last for a very long time and the beam is adjustable. My only gripe with this product is the way the beam is adjusted, the slide to focus the beam moves easily and does not stay in place. Perfect for sticking in the car or in a purse.
I have a lot of flashlights! Some are much more expensive than these but these are my favorite lights. They are a perfect combination of size, brightness and flexibility. I like the zoom function, I like the single battery, I like the pocket size. They work great and last a long time. My only dislike is that some of them (I have 6-7 now) have multiple modes. I prefer just a single mode. I never need a dim mode or a blinking mode.
Decent quality and no issues. Not 300 lumens, but is bright enough for what it is. Best part is that it works great with a single AA battery!
I bought four of these lights for a camping trip with the kids. They were the perfect buy for the little ones. They are easy for the little ones to operate and only use one AA battery.
Great little lights. Very bright for just one double AA battery. I have 5 of these and 2 larger lights that take one lithium rechargeable, those are really bright.
These are the coolest little Cree lights ever. Very small works for about 5 hrs on one AA battery, and is  probably pushing out at least 180 Lumens. Cant beat the pair for the price!
