Solar watches are a useful gadget that can keep time without daily winding or batteries, and just need one resource to work: solar energy. However, what if you\u2019re in a pinch and need to charge your solar watch, but don\u2019t have access to any sunlight? That leads us to a popular question.\n\n\n\nCan LED light charge a solar watch? Yes, LED light can charge a solar watch, although it isn\u2019t as powerful or as fast-charging as natural sunlight. You should try to avoid charging your solar watch with LED light unless you\u2019re in a pinch.\n\n\n\nCharging solar watches can be a little more tricky than just setting your watch out in the sunlight, especially if you want to charge one with LED light. To make sure you\u2019re getting the most use out of your solar watch, we\u2019ll walk you through the essential things to know about solar watches and charging them. \n\n\n\nCharging Solar Watches: What You Need to Know \n\n\n\nOwners of solar watches have often experimented with different ways to charge them. Although solar watches are really relatively simple to charge with natural sunlight, sometimes people can get in positions where they don\u2019t actually have sunlight to charge their solar watch. That\u2019s where alternative light sources come in.\n\n\n\nMaybe a certain area doesn\u2019t have enough exposure to sunlight to charge a solar watch. Maybe at the time your solar watch needs charged, it\u2019s dark outside or there isn\u2019t direct sunlight near your home.\n\n\n\nMaybe you\u2019re in a pinch and just need a little more power - but don\u2019t have a chance to take your watch off and let it soak up some rays. Maybe you\u2019re secretly a vampire. Whatever the case is, we get it! \n\n\n\nRegardless of how you want to charge your solar watch, we\u2019re going to walk you through some of the basics of solar watches and some of the best charging tactics for them. We\u2019ll also discuss how you can charge a solar watch with an LED light, but why it might not be your best or most effective option. Let\u2019s get down to it.\n\n\n\nSome basic information about solar watches \n\n\n\nYou\u2019ve probably gathered this by now, but solar watches are watches that are powered (entirely or partly) by a solar cell.\n\n\n\nBack around the 1970\u2019s when solar watches first emerged, it could be pretty obvious that your watch was solar powered; the solar cells were easier to spot and see. Nowadays, solar powered watches are more common and better built; you may see a solar watch without even realizing it\u2019s solar powered.\n\n\n\nSunlight (and yes, artificial light) are absorbed by the solar panel(s) on a solar watch. The solar power converts the sun\u2019s rays into electrical energy, which is used along with a rechargeable cell to power the watch. \n\n\n\nBecause of their rechargeable cells, solar watches can work day or night, or in low-lit areas and under clothing. The rechargeable cell holds the energy that was absorbed from the sun, giving power to the watch until it runs out of energy and needs to be charged again.\n\n\n\nCharging solar watches: natural versus LED light \n\n\n\nThe cat\u2019s out of the bag by now; you know that both sunlight and artificial (including LED) light can charge solar watches. How can you do it, though? Let\u2019s take a look at charging solar watches with both natural sunlight and LED light.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=gpAC0q4LmSQ\n\n\n\n\nCharging times: natural sunlight versus LED light\n\n\n\nWe mentioned before that charging your solar watch with LED light is slower and less powerful than using natural sunlight. To give you perspective, let\u2019s lay the timing out for how long your watch needs to be exposed to light for a full charge and temporary charge.\n\n\n\nYou\u2019ll see in the tables below that it takes significantly longer to charge a solar watch with LED light than it does with natural sunlight (we\u2019re talking almost 8 times longer!).\n\n\n\nLight time needed for a full watch charge\n\n\n\nLight sourceCharging time until full batteryNatural Sunlight (full sunlight)20 hoursNatural Sunlight (cloudy weather)60 hoursLED Light (artificial)150 hours\n\n\n\nLight time needed for a temporary (24 hours) watch charge\n\n\n\nLight sourceCharging time until 24 hours chargeNatural Sunlight (full sunlight)3 minutesNatural Sunlight (cloudy weather)9 minutesLED Light (artificial)3.5 hours\n\n\n\nCharging solar watches with natural sunlight\n\n\n\nLet\u2019s walk through the step by step process of charging a solar watch with natural sunlight.\n\n\n\nStep one: check your indicator\n\n\n\nSolar watches should have an indicator bar that shows the level of charge the watch has left. If your indicator says \u201czero\u201d or \u201c0,\u201d it\u2019s time to charge your watch!\n\n\n\nYou may also notice your watch\u2019s time can\u2019t be set or that the buttons aren\u2019t working. Additionally, your second hands may be moving in two-second increments instead of one-second increments. These are also indicators that it\u2019s time to charge your watch.\n\n\n\nStep two: place your watch near the light source\n\n\n\nIf your solar watch does indeed need charging, it\u2019s time to place it near the natural light source. Direct sunlight is best, so window sills are an ideal area.\n\n\n\nIf you\u2019re driving, you can also place the watch on the dash of your car while driving, or place your hand on the window sill of the car. Just make sure your sleeves are out of the way first.\n\n\n\nCharging solar watches with LED light\n\n\n\nCharging your solar watch with LED light is mostly the same in principle as charging your watch with natural sunlight. Step one is the same as with charging your watch with natural sunlight; first check your watch\u2019s indicator to make sure it does indeed need charged.\n\n\n\nNext, place your watch near your LED light source. The CoolFire Solar Watch Fast Charger from Amazon is an excellent choice. Smaller LED bulbs are best as they are safest for your watch (we\u2019ll discuss this in the next section in more detail).\n\n\n\nHowever, no matter what LED source you choose, place your watch at least 20 inches from the light source and let it charge. This distance will keep your watch from potentially being damaged by the LED light source.\n\n\n\nProtecting Your Solar Watch: Charge With LED Light Carefully\n\n\n\nThere are some potential risks to your solar watch with incorrect use while charging with LED lights. LED light and other artificial light can actually be harmful to and damage your solar watch.\n\n\n\nTo make sure you\u2019re charging your solar watch safely with LED light, follow these tips!\n\n\n\nKeep your watch a safe distance away from the light source\n\n\n\nHeat can damage the polarizing film of solar watches, and can cause permanent damage. LED light and other artificial light sources can put off a lot of heat. Because of this, it\u2019s important to keep your watch a safe distance away from the light source. At least 20 inches is a safe bet.\n\n\n\nUse a smaller, low lux bulb\n\n\n\nUsing a smaller or low lux bulb to charge your solar watch with LED light will help with the heat issue. Smaller bulbs and low lux bulbs put off less heat. So, while it may take a little longer to charge your solar watch with these, it\u2019s much safer. \n\n\n\nDon\u2019t charge your watch with LED light all the time\n\n\n\nUltimately, the most efficient and safe way to\ncharge your solar watch is with natural sunlight. So, while you can charge your\nwatch with LED light, try to avoid doing it constantly or all the time.\nYour watch will be safer, last longer, and charge faster!
