There is an automatic PIR sensor on the top of the solar light pole, which can immediately activate the LED in the absence of light to provide a brightness of 150 lumens. In addition, LED roof lights also have crystalline solar panel technology, which has a higher conversion rate than other technologies. Regarding the construction of the solar column, it is based on durable and rust-proof cast aluminum, designed to withstand harsh weather conditions.

It can be easily installed underground by using the grounding nail provided in the product, making it easy to install. It can be installed without wires. LED pillar lamp fixtures are used to replace existing garden street lights, garden lights, etc. Once the sensor detects that there is no sunlight, the solar lamp post will automatically turn on/off. Outdoor LED column headlights also have an on/off switch that can manually activate the solar lampposts as needed. BBier can manufacture 15w 20w 25w 40w 50w solar lamp pole heads, the luminous efficiency is 120lm/w-150lm/w, 3 years guarantee.

Another factor to consider when choosing a solar street lamp post is the charging and discharging time of the battery. This factor is completely related to the battery capacity, the power/efficiency of the solar photovoltaic cell and the solar resources available in your area. If your area has good solar resources, you can choose a battery with a larger capacity. The charging and discharging time should usually be specified by the manufacturer. A charging rate of 6-7 hours is good enough, and a good rate of discharging should be between 10-12 hours.
