If the solar panels are subpar, the lights may struggle to gather sufficient energy, requiring higher wattage. Not only does this lead to diminished performance during cloudy days, but it may also impact the overall lifespan of the lights. Therefore, it’s beneficial to consider the type of solar panels alongside intended wattage when arranging for outdoor illumination.

1. LIGHT OUTPUT (LUMENS)

While wattage often serves as a metric for brightness, it’s essential to consider lumens, the actual measurement of visible light output from a source. Higher wattage generally correlates with increased brightness, yet different types of bulbs produce varying lumen levels. For instance, standard LED lights offer greater lumens per watt compared to traditional incandescent bulbs.

10 to 15 lumens are typically adequate for pathway or garden lighting, while security lights should aim for around 700 to 1,200 lumens or more to ensure good visibility. Considering the intended use in terms of lumen output reinforces the

importance of wattage selection in overall outdoor lighting schemes.
