FREQUENTLY ASKED QUESTIONS

WHAT IS THE DIFFERENCE BETWEEN SOLAR FLASH LIGHTS AND TRADITIONAL LIGHTING SOLUTIONS?

Solar flash lights differ fundamentally from traditional lighting solutions such as incandescent and fluorescent bulbs in several aspects. Primarily, the source of energy vastly distinguishes the two; solar flash lights rely on renewable solar power, which is harnessed through photovoltaic cells, while traditional lamps depend on the electrical grid, which often utilizes fossil fuels or other nonrenewable energy sources. Additionally, solar flash lights come equipped with rechargeable batteries that allow them to store excess energy for use during the night or when sunlight is not available. In contrast, traditional lighting systems typically remain fixed to a constant energy source, limiting their utility in remote areas.

Another major distinction lies in sustainability and environmental impact. Solar flash lights produce zero carbon emissions during operation, contributing positively towards environmental conservation. Meanwhile, traditional lighting systems, especially those powered by fossil fuel-generated electricity, often result in significant carbon emissions, contributing to climate change and air pollution. Lastly, in terms of long-term costs, while the initial investment for solar flash lights may be higher, they tend to yield savings over time due to reduced electricity bills and extended lifespan owing to LED technology.

HOW DO SOLAR FLASH LIGHTS WORK DURING CLOUDY DAYS OR AT NIGHT?

The operation of solar flash lights during cloudy conditions or nighttime relies on their ability to store solar energy during periods of sunlight.
