Frequently asked questions

What is direct sunlight?
Direct sunlight means that the sun’s light is directly hitting the solar panel. For example, if you were standing outside under the sun with nothing obstructing you and the sun, then you would be in direct sunlight. If you were standing inside, you would be getting indirect sunlight but no direct
rays from the sun. Solar panels always need direct sunlight to charge. If in doubt, think of it this way; if you were Luci and you were able to directly see the sun, then you would be in direct sunlight!
It’s cloudy, will my light still charge?
Yes, but it will charge at a slower rate than on a bright, clear day. As your Luci charges via the red and violet frequencies of visible light, the charge times will vary based on the UV index or overcast skies. Generally speaking, the higher the UV index, the faster the charge.
Will my light charge under indoor lighting?
The sun generates significant red and violet frequencies (which charge your Luci), whereas your ordinary indoor lights emit a tiny fraction of that UV.
We recommend you go straight to the source and put your Luci directly in the sunlight from a windowsill or, for the best results, outside! Luci is durable and completely waterproof.
Can I charge your products from my car dashboard?
We advise against charging on a car dashboard. On a hot summer day, your car dashboard can reach temperatures of up to 160ºF (71°C) which exceeds the temperature limit of our products – 122°F (50°C).
What’s the difference between charging the light via USB or the solar panel?
Speed! Charging via USB is ~6x faster than via solar due to the input power. Whether charging via solar or USB however, the outcome remains the same – a full battery charge. Our advice is to charge via solar for a natural source of power, but if you’re in a pinch, charge via USB.
Can my light be left outside in the rain?
Yes! It can be left out in the rain but we wouldn’t recommend leaving it out in strong rainstorms for extended periods or submerging it in water.
Can I charge a device and use my light simultaneously?
Yes, we love multi-taskers! You should be aware though, that as you’re charging your device, you are depleting the battery in the light. We recommend
checking the battery level of the light frequently to make sure that you have enough charge to last throughout your activity.
Are the bulbs shatterproof?
Yes, the bulbs are super durable. This product was built to live outside and take knocks, accidental stomps, or even the occasional cooler drop.
