Do you know how many lumens you need for your solar street light? Today, we’ll help you choose the best lumens/brightness for solar street light applications.

What is a Lumen and Why It Matters?

Lumen measures how bright a light is, or the intensity of brightness it emits. Nowadays, we use this unit of measurement to specify the light output of solar street lights. For example, defining the brightest LED for solar street lights can mean finding a solar street light with the highest lumens.

The 3 key points to judge the quality of the solar lights are the brightness(lumens), the lighting time at the night, and the cloudy days and the life span. The main material that determines the life of solar street lights is the lithium battery.

What is Watt and Are Higher Wattage all in one solar street Lights Brighter?

Our once convenient way of buying an all-in-one solar street light is by choosing from different watts printed on its packaging. We judge a light’s intensity by its watt rating. The higher the watts, the brighter it is.

Watt is a unit of measurement for power draw or the amount of electricity the solar street light consumes. It means that a 100-watt solar street light takes up 100 joules of energy to produce light in 1 second.

We used this proportionality way of saying how bright a lamp would be based on how much power it consumes. But eventually, watts can only accurately determine how much we have to pay for electricity bills.

On the other hand, lumens measure the light intensity of a lamp – not counting how much electricity it draws.

Now that you know that it makes more sense to specify brightness in lumens, how would you know if you got the right light brightness you need?

How Many Lumens are Needed for all in one Solar Street Lights?

With the right solar street light manufacturer, you can easily replace existing street lights with solar-powered street lights that can last for 30 years, with minimal maintenance and operation cost.

As the third-generation light source led can save more power to keep the same brightness. We calculate the brightness by the lumens(lm) but not the wattage. Because the brightness is decided by the luminous efficacy (lumens per wattage).

The luminous efficacy of the lamp is 12-24 lumens per wattage only. And the Compact Fluorescent Lamp fixtures can reach 50-60 lumens per wattage. And led can generate more lumens per watt (lm/w). Then the led lights fixtures in 2010 can reach 100-110 lumens per wattage.

In the market in 2020, different types of lead can generate different luminance efficacy (lm/w). Some led chips can reach more than 200lm/w, some can be only 130lm/w around. So the best to calculate the brightness is not by led power, but by the lumens.

In the summary of misunderstanding one and misunderstanding two, here we also want to remind you that the solar light led power is always labeled as much higher than the real led power.

Take the solar flood lights in Amazon shop, for example, they have labeled 100 wattage solar floodlights, 200 wattage solar floodlights, and 300 wattage solar floodlights. The so-called 300watt solar flood lights, real led power is 15 watts at the highest. Because you can easily find that the solar panel power of it is only 25watt to 30watt. How can such a small power solar panel support 300Watt lead to power long-time lighting? No more than one hour!

Another question or factor to consider when sizing solar street lights would be considering the number of Lumens per radius illuminated and how high should the light be placed. Clodesun, for example, how many lumens are necessary for properly lighting 20m when the light is placed at 8m height.
