The higher the waterproof rating, the better outdoor solar light is?

Waterproof is the basic requirement for Outdoor Solar Lights products.

Outdoor solar lights are commonly used as outdoor applications. Water is inevitable cannot be avoided in outdoor locations. Therefore, a relatively higher level of waterproofing is required in order to achieve better performance in such environmental conditions. Often, we come across the label of IP65, IP66, and even IP67 in product packing. So, is the higher the waterproof level, the better for the product?

(1) Waterproof is Necessary for Solar Outdoor Products

For the above question, first, we need to understand why waterproofing is needed. During the long-term use of outdoor solar lamps, some liquid usually will condense on the solar-powered products due to the influence of day and night temperature changes. As we know that from middle school, when gas or vapor condenses or is condensed, it changes into a liquid.
In addition, the water of rainfall will splash directly onto the solar light product. If typhoons or hurricanes patronize to an area, then strong storms will bring water to try to destroy products exposed in unsheltered place. Therefore, there must be a sufficiently strong level of waterproof for the outdoor lighting system.

(2) Understand Waterproof Standards to Facilitate Product Selection

In this regard, we need to understand what the standard of waterproofing is. What kind of impact can each level of waterproof protect against for outdoor solar lighting?

For example, there is a product with IP65 label. Let’s see the meaning of IP, 6, 5 respectively.

The IP (INGRESS PROTECTION) protection level system was drafted by the IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifies electrical appliances according to their dust and moisture resistance characteristics. The IP protection level mark is composed of two numbers.
The first number indicates the level of the appliance to prevent dust and foreign objects from invading. The foreign objects include tools, fingers of human beings, and other small objects. All these objects can not touch any area that contains electricity insider the electrical appliance, outdoor solar LED lights, to avoid electric shock.
The second number indicates the tightness of the appliance against moisture and water. The higher the number, the higher the protection level.

As an example, IP65 Solar LED Street Lights – IP rated as totally dust particulate protected and against water projected from a spray nozzle.

(3) General Advice When Selecting the Product Waterproof Level

High waterproof rating means a high manufacturing cost naturally. In order to deal with extreme weather that may encounter, expensive outdoor solar lights products with high waterproof rating are the utmost choices.
A) If there is not much storm and rain in an area and it is not a place often by typhoons/hurricanes, you can choose a solar outside lights product with a lower waterproof level of course. In desert zone of North Africa and the Middle East, the waterproof rating can be relatively low. All our products can meet the weather conditions in these places. For example, the S2 series can easily handle the conditions.
B) If it is in the Gulf of Mexico, the Caribbean, or the Pacific Islands, then high grade waterproof products need to be considered.

Waterproofing can reduce the risk of corrosion caused by water infiltration. However, according to our industrial experience, corrosion protection is the biggest issue for products used by the sea. After the metal is corroded, the water resistance is deemed to be poor, Waterproof becomes meaningless, regardless of how high the waterproof level has been made previously.

For this reason, it is critical that we shall choose the proper raw materials of the product and control the following manufacturing process. Efforts to this end, we have also particularly strengthened our investment in materials and processes to ensure that the products can meet the different applications of users. For instance, the battery case is water-resistant with an IP68 rating. Other companies will not put so much effort into adopting high standard process in components that cannot be seen by the naked eye of customers. Our S2 and S3 series solar powered led outdoor lights products are equipped with an IP68 waterproof batteries box as standard.

From this point, waterproof rating is a momentous aspect of product selection. But it is not the only criterion for selection. Comprehensive consideration of all aspects of the product is always the safe way. As for how to better choose the suitable solar led lights product, we are happy to provide our expertized solution in this regard.




Top 3 factors to choose outdoor solar lights properly

Users or consumers often find there are lots of key factors in selecting outdoor solar lights,hence, we figure out top 3 factors here.

Top 3 Factors to Choose Outdoor Solar Lights

We all understand that we shall make a good quality product for our users across the world. No matter they are coming from Malaysia, Saudi, UAE, Sweden, Brazil, Australia, South Africa, Namibia, Uganda, or elsewhere, they will all be treated with a high standard quality product. Mostly, the solar-powered street lights are all in one type in the market. All in one is actually three in one type. Three means three major parts for solar street lights, i.e.  solar panel, LED light, and battery. Therefore, I am recommending use to take a look at these top 3 factors before buying solar-powered street lights. Let’s begin.

It took around two decades for photovoltaics (PV) or solar PV to become a mainstream electricity source from small scale applications. Price in the past could only be accepted by users like military and aerospace who don’t really care about the cost too much. Now, the price has dropped to a level that is affordable to civil users.

Solar panel energy has been developed for many years. Technically speaking, the product is mature enough. Usually, the high-efficiency solar cell will come with an MPPT controller for stable performance. The controller also takes care of light absorption in summer and winter.

As regards to the efficiency, monocrystalline solar panels are higher efficiencies and sleeker aesthetics than polycrystalline solar panels. Doubtlessly, polycrystalline panels are sold at a lower price.

Both monocrystalline and polycrystalline solar panels serve the same function in the solar PV system: they capture energy from the sun and turn it into electricity. The technology is so powerful that it can even work and provide lighting under weak light conditions. This is especially helpful in wintertime for high latitude areas like Sweden and Canada. Our customer in Sweden is continuously buying solar-powered street lights from us which is a great honor to us. It is sure that we have installed a special component unit for Sweden market which need complementary power in winter.

As mentioned, the solar panel industry has been developed for so many years. The solar panel itself is guaranteed with at least 20 years lifespan in most cases.



The top 3 factors for outdoor solar lights go number 2. LED chips are various and different chip vendors provide respective lighting solutions. Bridgelux, Cree, Lumileds, Nichia, OSRAM and Philips are common choices of solar lights factories who cherish their product quality and reputation.

For example, when we choose Bridgelux, we will take into consideration of LED power and lumen efficacy into consideration after comparison between brand and brand. Bridgelux has great performance regarding ESD protection. ESD protection devices (anti-static components) protect a circuit from Electrostatic discharge (ESD). The value of ESD for Bridgelux can be as high as 3000V. The product of the brand has high stability because it has a double electric shock structure and has 6 protective films on the surface. The factory is easier to operate in the downstream production process while the product yield is better controlled. At the same time, the light decay is less.

As a whole, other brands are also being picked for use when we produce a specific item since we need to consider the system output performance.



The battery unit is outsourced from battery vendor. If an outdoor solar light manufacturer wants to use a low-cost component, then a lead-acid battery is possibly being used. The lead-acid battery has one of the lowest power-to-weight & power-to-volume battery designs in existence, making it big and heavy for the total amount of power it can put out.

In past years, quite many off-grid energy systems are equipped with lead-acid batteries. Now, most of them are defunct or replaced. People are turning to the solution of LiFePO4 lithium-ion battery.

LiFePo4 battery pack with 2000 times long life circles which is 3 times longer than Lead-Acid battery. When you browsing on the internet shopping site for outdoor solar lights, some vendors will indicate the warranty time of the product. Some warranties are so short that you will question yourself for what circumstance a customer will buy and question sellers for what kind of product they are selling at such a low price.

Moreover, please be aware of some suppliers who are using second-hand batteries taking down from electric vehicles.

Above the top 3 key factors are of fundamental importance as they are the main parts of outdoor solar lights.

We are carefully selecting our battery vendor and use the lithium battery product that can support a longer lifespan which is beneficial to both customers and us.
