fan and light rechargable via USB 3 modes low - 4 hours med - 2.5hrs high - 2hrs 20 lumen

Found it! Hold the power button on the back in and the lights comes on, hold it again to turn it off.

Just bought this item for camping, we think it will be fine to have on when sleeping, the fan seems to work fine. But, how do you turn on the light, don't see a button or switch to control the light. Please advise!
