Only the low light setting works

When the lamp detects the battery charge is reaching its end, it will go into an energy saving mode, limiting the light settings to the lowest option only. To get access to all the light settings again, recharge your lamp. The green light will start when its charging up. When the battery is fully charged it will show steady green. It is possible to charge with either the solar panel under the sun, or with a USB charger plugged to the electric grid.
