No wiring and easy to install. To supplement public lighting in rural areas and outdoors, solar lights are a convenient choice. In this issue, we reviewed Yinglang 3 solar lights , both for home use and public use. They have a long battery life and are bright all the way home at night.
Gaide reviewers concluded that
solar lights that use battery storage can stay on for more than ten hours and illuminate the whole night, which is worthy of boasting. Yinglang's flagship YL005-13A street light has been measured to last for more than 63 hours on full power, and is bright almost the entire time, so it is not afraid of occasional rain. It has an exclusive patented mutual control function. The first light senses the human body or vehicle and highlights, and the second and third lights in front also highlight. According to actual measurements, the front field of view can be widened to about 40m, making it bright all the way home at night.
floodlights are usually installed on the exterior wall to illuminate the yard. In the test of Yinglang YL005-11A floodlight , the battery life is comparable to that of YL005-13A street light, and the brightness is even better. The shell is made of tempered glass and metal plates, which is particularly rare in the market and can withstand extreme weather such as thunderstorms.
Yinglang YL002-6B wall lamp is not very bright. According to actual measurements, it is almost the same as the 10W LED bulb . If you only need to deal with light usage scenarios such as opening the door at home and looking for keys, it is very cost-effective for less than 100 yuan. Most solar wall lamps on e-commerce have exposed light sources. The YL002-6B lamp head is equipped with a lens, so it is not dazzling to the reviewers when looking directly at it. It also has a colored light function, which makes it fun to use as decoration.
Product background
Brand background:
Yinglang, a veteran solar lamp enterprise, was founded in 2004 and has deep experience in the domestic solar lamp industry. It specializes in the research and development of solar light chips and circuits, holds several representative patents, and is also a rare professional manufacturer that has opened an online store. In a situation where big brands are unwilling to engage in e-commerce and e-commerce is unreliable, Yinglang is a relatively convenient and worry-free choice.
Product parameters: The paper parameters reach the high-end version
Among the Yinglang e-commerce lamps, the three lamps selected for evaluation are the top-end models of their respective lamp types. The important hardware parameters are as follows.
● The street light is of engineering grade, with battery capacity and luminous flux twice that of similar e-commerce products.
● Floodlights are generally darker than street lights and are installed on exterior walls to illuminate the yard or placed on the ground to illuminate the court. But the configuration of this floodlight has been increased to a quasi-engineering level.
● The purpose of the wall lamp is not as "hard-core" as the previous two. The 600lm luminous flux + 2200mAh battery belongs to the middle and upper reaches of the market, just reaching the household standard.

simulates the installation height of general usage scenarios. Street lights and floodlights shine down from a 2.7m high ceiling. The effect is quite bright when viewed directly with the naked eye. It is not recommended to look directly at it no matter how far away it is. We have actually measured that their peak illumination at the center of the ground reaches 110 lx, which means that without an auxiliary light source, they can barely meet the requirements for reading and writing.

battery life test
In addition to the well-known battery capacity, battery life is actually closely related to the conversion efficiency of photovoltaic panels. In late November, when the sunshine intensity in Guangzhou has been greatly reduced, street lamps and floodlights can continue to charge until nearly 18:00 at night, and the light conversion efficiency is very high.
It was almost dark, and the street lamps and floodlights were still charging.
The five lamps were charged for a total of 11 hours on the embedded southeast balcony. After only one charge, the most durable street lamp and floodlight stayed on for more than 63 hours in the long-bright high-brightness mode. Based on 13 hours per night, a full charge can last for 4 and a half nights, and there is no problem in areas with severe weather changes. However, there was also a street lamp that was placed too far away and was blocked by the wall and could not be charged. It only lit up for 2 hours. It is recommended that when installing a photovoltaic charging panel, it should be exposed to direct sunlight as much as possible. The
wall lamp can last half a night when fully lit. Among the three models, it has the smallest photovoltaic panel area, and its battery capacity is less than 1/10 of that of floodlights and street lights, so this result is not bad. In actual use, more people will choose the induction mode, which consumes much less power than the always-on and high-brightness mode, which is just enough for areas with many sunny days.

Blocking photovoltaic panels to simulate darkness
The function of high brightness when people come and low brightness when people leave is very popular with consumers, but the sensitivity of different manufacturers varies. Of the three lamps reviewed, both street lamps and wall lamps have sensor modes. The sensing performance of both is relatively in line with daily usage habits - the light will turn on when you are three to five steps away from the door, without being sluggish or overly sensitive.
Approach a wall lamp with an installation height of 1.8m from the front
Approach a wall lamp placed on the ground from the side
Approach a street lamp with an installation height of 2.7m from the front
Due to the high installation height of a street lamp, the sensing distance of a lamp is much shorter than that of a wall lamp. At this time, Yinglang's patented mutual control function can be regarded as a compensation: if two or more Yinglang street lamps are installed, and a person walks under the first lamp, the first lamp will be highlighted, and the second and third lamps will be turned off. The electrical signal to the first light is highlighted in advance. We have actually measured that the farthest mutual control distance between two street lights is 20m. When three lights are linked, people's field of vision can be extended to 40m at night.
When a person walks to street lamp A, lamps B and C will light up in advance after receiving the signal from lamp A.

is equipped with remote control, but the sensitivity is slightly poor and the button feel needs to be improved. Screws are provided, and installation is very simple, but you need to drill holes in advance with an electric drill.
Purchasing Suggestions
1 and YL005-13A street lamps feature engineering-grade configurations. Their brightness and battery life are twice those of similar e-commerce products. They also have the function of directing the front lights to light up the rear lights at the same time, making the field of view clearer when walking at night.
2. If you want to illuminate open areas such as stadiums and courtyards, it is recommended to choose YL005-11A floodlights. The brightness is more uniform than that of street lights. The tempered glass + metal shell is solid and durable, and it is not afraid of outdoor wind and rain.
3 and YL002-6B wall lamps are light and beautiful, with many humanized details. The lamp head is equipped with a lens to make the light soft and non-glaring; it can emit ambient colored light. It is recommended to use it with a light strip as a home decoration. However, the brightness and battery life are on the entry-level side, making it less friendly to areas with a lot of rainy days.
Maintenance Guide
Install photovoltaic panels flat or tilted?
China has a vast territory, and the incident angle of sunlight varies greatly from place to place. Therefore, it is recommended to calculate the appropriate installation angle based on the latitude and install it tilted toward the south. For the calculation method, please refer to the following table: How to maintain
after it is installed?
Just like ordinary street lamps, they can be wiped regularly. In particular, dust on photovoltaic panels must be cleaned frequently, otherwise it will affect the power supply.
