10000mAh Rechargeable 3000LM Tent Light Camping Light, 6500K 24Hours Long Play Time , Outdoor Night Market Light Night Fishing Light Emergency Lights for Hurricane Tsunami disasters (Colorful)

The light comes in a box with a USB charging cord, a steel plate with self-adhesive backing and a manual. It does not include a USB charger but most people have those already. There are four charging status LEDs on the side, next to the on/off button and USB power input and output. On arrival three LEDs were lit when turning on the light. I charged it until all four were lit. This light has white and RGB LEDs. However the manual was for a slightly different model with white light only. This light operated slightly different than the manual indicated.The light has a hook on the back that can be used for hanging the light or as a stand to keep the light at about 45 degree angle on a flat surface. The back also has a magnet that can hold the light on steel surfaces. With the included adhesive steel plate you can attach the light to non magnetic surfaces. It looks pretty well sealed and should be able to handle some rain.After the first push of the button the light comes on at full brightness. If you push it again within 10 seconds, it switches to RGB color mode which slowly changing colors. If you push it again, you still get the same color changing mode with no noticeable difference.When the white light is on, you can adjust the brightness by holding in the button. In the color mode the brightness can not be changed.My main purpose for this light is as a backup light source during power outages. To check how long the battery will last I turned on the light at full brightness.After 2 hours all four charge LEDs were still on. After 3 hours, two LEDs were on and the light was still very bright. After 4 hours, only one LED was on. After 4.5 hours the charge LED starting flashing and the light got dimmer. After more than 5 hours the light was not very bright and I turned off the light. When turning it on again, it would come on bright but would shut off after a few seconds.This light is very bright and can light up a relatively large room. At a reduced brightness it should last a lot longer than 5 hours. It is a nice light to have for camping, work light or during power outages. It can also be used as a power source to charge other devices, such as cell phones.
