Using this tent light is a breeze. First, insert 3 AAA batteries (not included) into the battery compartment. Then, you can choose one of the 4 brightness levels according to your needs. You can hang it up using the split - loop handle wherever you want light, like inside your tent or above a picnic table. When it comes to cleaning, use a damp cloth to wipe the silicone shell. Since it's water - resistant, a little splash won't harm it, but don't submerge it in water. Keep it in a dry place when not in use. If it falls or gets bumped, don't worry as the durable silicone can handle it. Check the batteries regularly to ensure it runs smoothly.
