DANGER
- DO NOT throw the light directly into human eyes. This may cause temporary blindness or permanent damage to the eyes.
- DO NOT cover the light head when the LED light is on, or place the LED light head on the ground. The radiation energy of the LED light may cause damage to the LED light itself, or even result in burning to flammable objects.
WARNING
- Keep out of reach of children.
- The light contains a lithium-ion battery. Certain restrictions may apply to this product when traveling, especially when traveling by air. Always check with your carrier for specific restrictions prior to traveling with this product.
NOTICE - Store the light at room temperature in a dry place. Avoid moisture, or extremely hot or cold.
- Store the light in the charged condition. Avoid “deep discharge.” Battery life will decrease if the light is stored in a fully discharged condition.
- Over time, the run time of the battery will diminish. Expect about 500 full charges, depending on care. After a full life, the battery will continue to charge but with a lower run time.
- When the run time is unsatisfactory, please recycle. Do not open the case of the light or incinerate.
