I was pleasantly surprised with this LED work light. It is lightweight and seems to be well made. Housing is mainly plastic but appears durable.
The controls are nice and easy to operate. You can step through the brightness in 25% increments or hold the button down and do stepless dimming and brightening. There are 4 small green LED indicators that show you the charge in the battery. Charging is via included short USB C cable. Note: there is no USB charger adaptor included. But, most of us have them laying around the house! Like all rechargeable devices, your charging time will vary based on the current your charger outputs. I used a typ small charger and battery charged 25% fairly quickly. Battery depletion seems good also. I ran it for a while on 100% brightness and battery only dropped 25%. I estimate it would last a couple hours at full brightness. You can stretch battery life by reducing the brightness level. It also works as a power bank to charge USB devices like a cell phone. Your usage time as a power bank will vary depending on the size of the battery in your cell or device.
I like the U shaped handle on top. It is configurable (extends/retracts) and it has 2 clamping knobs so when you get it set up as you like, it stays put! The handle also has a hook built in, in the middle of the top of the U. That is handy to hang the light on a nail, cable etc.
There are two very small rectangular magnets on the back surface of this light. You can pretty much forget about using them. I placed the light on a clean vertical painted metal plate and the light slid slowly down. I tried sticking it to the wall in my metal pole barn and it slid off. If you get it to hold, then bump it or the surface the light falls! It would not stay stuck to the underside of the hood of my truck. Bummer, as I wanted to use it to work under the hood on vehicles. Better magnets would fix this issue. I think I may be able to find a couple small magnets with holes in the center and replace the ones that came on the light. If you do not plan on using the magnetic mounts (like in a tent), the magnets won't be an issue.
The light is pretty bright at full power. I do not believe it is 10000 lumens as the description claims. I have some 7500 lumen lights that appear about the same. That said, it does light up the area under an engine hood, trunk, would be a nice light for a camp site, tent or a medium size room when power goes out. It will be nice for repairs in closets, under sink etc.
A couple of the LEDs are red when lit. I suppose to be used during an emergency. They flash. Not very bright. You are not going to see them 100's of feet away. Not something you'd use next to a broken down vehicle. To be honest, I doubt I will ever use them.
Overall, I think it's a decent light for the cost. As long as the internal battery can be charged and discharges slowly with time, it will be useful. Only time will tell. I would recommend it.
