How To Choose The Right Solar Flashlight?

How To Choose The Right Solar Flashlight

With solar technology becoming more accessible by the minute, more and more companies are making it a point to roll out more of their solar-powered devices. As mentioned above, the majority of the organizations have rolled out their solar flashlights. However, when there are numerous options at our disposal, making a choice can be challenging. To make that decision more accessible every time. We have listed a few parameters that can help you choose the suitable solar flashlight when considered.

1. Output Light

The more lumens the light has, the brighter it shines. The output light directly refers to how bright your flashlight is. Though all LED lights are manufactured equally, the lumens tend to differ significantly. When it comes to choosing a flashlight, it is always better to judge the light via lumens than watts since lumens directly refer to the overall brightness of your flashlight. 

To make it easier, here is a watt-to-lumens conversion chart.

  • 40 watt incandescent bulb = 450 lumens
  • 50 watt incandescent bulb = 525 lumens ( Standard House Bulb )
  • 60 watt incandescent bulb = 600 lumens
  • 75 watt incandescent bulb = 1000 lumens
  • 100 watt incandescent bulb = 1500 lumens
  • 150 watt incandescent bulb = 2500 lumens

2. Charge Time

Every solar-powered flashlight is manufactured equally. However, the charge time required for each tends to differ. On average, most solar-powered flashlights take around 6-8 hours to be fully charged, whereas some require just 4 hours. Meanwhile, some require approximately 12 hours of direct sunlight to be fully charged. While the manufacturers will brief you about the overall charge time, it is always best to read the reviews to estimate the overall charge time. 

3. Water Resistance

This is one of the most important factors to consider when buying a flashlight. If you plan on using your solar flashlight outdoors, there are higher chances of getting wet under the rain. Therefore, always check to see if your chosen solar flashlight is water-resistant since this is a critical feature that must be present in every flashlight. 

4. Weight And Size

The larger and heavier the flashlight, the more space it will occupy. It is essential to check the weight and size of your chosen solar flashlight, especially if you are to take the flashlight during camping and other outdoor activities. A small and compact flashlight can be accessed quickly and is a great idea. However, a heavier flashlight can come in handy as a weapon. 

5. How Do Solar-Powered Flashlights Work?

As the name suggests, solar-powered flashlights harness the sun’s power and store energy in the solar cells. When exposed to sunlight, these solar cells absorb all the solar radiation and accordingly convert solar energy into electricity. This energy is then stored in the rechargeable batteries inside the solar-powered flashlight. Every time you turn on your flashlight, the stored solar energy is utilized by the solar cells, which emits light. 

Solar-powered devices are energy-efficient as they consume less electricity as compared to other incandescent devices. These solar-powered flashlights emit enough bright light to allows you to see during the night or in dark areas.
