Question: what batteries does it require?
Document: Put batteries in and light never worked.
Not as bright as I thought it would be. Needs batteries that are more expensive than the flashlight itself. Doesn't feel sturdy
Seems to be well made. I do not know about its performance since the batteries and charger are non functional.
Batteries were  not included. Batteries appear to be non-standard and are not available over the counter. I am an unhappy camper!
best flashlight for impressing people on camping trips.If you already have lights that use these batteries, you must own this one.
I really like how bright this light but, it uses 4 batteries and doesn't last long, the charge is used up very quickly.
the batteries do not fit as the compartment is to big and there is nothing for the batteries to make a connection with even if you rig it to fit the batteries. returning today!
That is true the sky ray king is so powerful . I use a 3400 protected batteries that will last long . It's a fantastical light
I wanted a bright flashlight and this sure fit the bill. It's the brightest I've ever seen. My only concern is how quickly the batteries will deplete.
The flashlight didn't work. Look at the design again and there is no way US AA batteries will work in this flashlight the design makes no sense. how hard can it be&#8230;it's a flashlight.
Answer: no
