Recently, our company has launched a new product called solar tube, which is mainly used for night snack stalls, street stalls, night fishing, camping, rural breeding farms, courtyard guardrails, etc. Compared to the existing solar tubes on the market, significant improvements have been made in both appearance and performance. From the appearance, our new solar tube retains IP65 waterproof performance and adds a hook design at both ends of the tube. The main purpose of this design is to facilitate hanging, installation, and flexible use. In terms of performance, firstly, the new solar tube has increased the built-in battery capacity, and the tube can continuously illuminate for about 12 hours when fully charged. Secondly, the new solar tube increases the number of tube chips, with three adjustable brightness levels and a maximum brightness of up to 70 watts, providing a wide radiation range. Finally, in the latest upgraded version, we have added USB charging function, and the light tube can be directly converted into an emergency power bank to charge the phone in a timely manner. At present, we have conducted tests on the new solar lamp tube, and the test customers have expressed that its functionality is relatively stable and the user experience is also good.
