Full Cutoff Wall Pack VS Semi Cutoff Wall Pack ?

 

What is a Full Cutoff Wall Pack VS Semi Cutoff Wall Pack ?

Many end users don’t know what is full cutoff wall pack as well as for some buyers in LED industry for quite a few years.

Today I’d like to explain all details to tell the difference between full cutoff LED wall pack VS semi cutoff LED wall pack VS LED rotatable wall pack

In order to help more people to understand these three types wall mounted lighting fixtures, so you can make the right decision to buy proper wallpack for your application.

There are three types of wall pack that is made in market. It is categorized actually based on the application.

Generally, wall pack lights are classified into four types, including; flood wall pack lights, full cutoff, semi cutoff, and up-down wall packs.

While the full cutoff and semi cutoff wall packs dispense their lights downwards, flood wall lights mainly distribute their lights outwards, and up-down wall packs distribute downwards and upwards.
If after all consideration, you think LEDs are the perfect choice to go with, but you are stuck with choosing with choosing wall packs.

Then after reading this article you will know the difference between them.

Full cutoff means that it is dark sky, all light is down, and comply with the glare requirement between 80° and 90°.

It indicates that there is no upward light. All lightbeam is just directed downward to the ground because the chip board is placed flat horizontally or using a light shield cover to stop the light go upward, so we see the light beam is fully cut off.

Full cutoff wall pack is usually used in a very narrow passage, which does not cause any glare or light pollution to the passengers and neighbors. It is more some kind of decoration to outdoor building or act as security light.

Semi cutoff wall pack is also called half cutoff wall pack.

Because its chip board is put in a slope, there are still some lightbeams can emit to the sky, so we say the light beam is half cut off or non-cutoff, some light go up, and some go down.

Semi cutoff wall pack is often used for a broad street and entryways or walkways, It is designed to direct light forward throw, much more further than LED full cutoff wall pack as a perimeter lighting.

You can see that these wall pack fixture is often installed a little higher on the outside wall in order to illuminate to far distance. Its beam angle is 90 degree, some lightbeam is able to emit upward to the sky or the wall.

Therefore, it is better to have no building, no wall at its front or within its illuminated coverage. It is usually used in exterior wall in parking lot, schools and hospitals, warehouse, shopping malls.

Another kind of LED wall pack – rotating wall pack.

It is different from the two kinds mentioned above, because its mounting angle can be adjustable.

It allows people to adjust its angle to direct light to the wanted place. Its angle is usually from 0 degree to 90 degree, or 0 degree to 270 degree.

Some wall pack head is adjustable, while some LED modules can be rotatable from up to down lighting. To some degree, it can be used for full cutoff wall pack or semi cutoff wall pack.

Therefore, you should choose the right LED wall pack for your application, whether you should choose mini, small and large wattage wall pack, because neither too dark nor too bright can bring discomfort to people’s eyes and insecurity to you and other pedestrians.

For example, if your residence is living very close to the street and you might not need the light extend to the street, which might cause a car accident.

If you don’t want a very wide or broad, large coverage of lights on the ground, you probably need a rotatable LED wall pack. You can coordinate the installation angle and light up that area specifically.

Another important thing that I want to point out is the material of cover. There are glass cover and PC or polycarbonate cover in the market.

PC cover might turn yellow as time goes by because of the sun’s UV rays, that might cause the diffuser lumen transparency rate very low, so if you don’t have a tight budget , we recommend to use glass lens if possible.

Semi Cutoffs and Full Cutoff LED Wall Pack Lights

Like we mentioned earlier, this kind of wall packs dispense light downwards, but it still provides an amazing intensity of light that supports safety and security. They are used in outside commercial buildings, garages, parking lots, hospitals and public spaces. They consume very little electricity and are very easy to maintain.

What kind of batteries are used in solar street lights?

 Batteries are the main equipment of solar street lights. At present, the batteries used in solar street lights mainly include lead-acid batteries, gel batteries, ternary lithium batteries, and lithium iron phosphate batteries. So which battery is the best for solar street lights?

The applications of solar street lamp batteries are mostly divided into the following categories:
1. Lead-acid battery: low price, suitable for low-temperature and high-rate discharge; sealed and maintenance-free; but attention should be paid to prevent lead-acid pollution, and if it is too bulky, it will be phased out. The plates of lead-acid batteries are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage of lead-acid batteries is that the voltage is relatively stable and the price is relatively cheap; the disadvantage is that the specific energy is relatively low, so the volume is much larger than ordinary batteries, and the service life of lead-acid batteries is relatively short, generally 300-500 deep cycles. Maintenance is relatively frequent, but because of the price advantage, it is still widely used in the solar street light industry.
2. Nickel-cadmium batteries: strong, cheap, economical and durable, and good low-temperature performance; but attention should be paid to prevent cadmium metal from polluting the environment.
3. Ni-MH battery: high-rate charging and discharging performance is good, pollution-free, green battery; small system is used, it is worthy of vigorous promotion.
4. Lithium iron phosphate battery: good high-temperature performance, large capacity, high charging and discharging efficiency, light weight, environmentally friendly and pollution-free; but its price is relatively expensive, and the charger is also selective. Lithium iron phosphate battery is a storage battery that integrates many advantages. It has higher specific energy, small size, fast charging, long service life, and good stability, but the price is the highest of all batteries. Its deep cycle charging times are generally 1500-2000 times. A set of lithium iron phosphate batteries can generally be used for 8-10 years under normal use, and can be used in an environment of -40℃-70℃. The scope is quite wide.

5. Ternary lithium battery: Ternary lithium battery has many advantages, it has high specific energy, small size, fast charging and high price. Its deep cycle times are about 500-800 times, and its life is similar to that of gel batteries, and the temperature range for use is -15°C-45°C. However, the ternary lithium battery also has its drawbacks. Its internal battery is not stable. If it is a ternary lithium battery produced by an unqualified manufacturer, it may explode during the overcharging process or in a high temperature environment. .
6. Gel battery: It is equivalent to the upgraded version of lead-acid battery. It is maintenance-free and solves the criticism of frequent maintenance of lead-acid battery. The colloidal electrolyte replaces the sulfuric acid electrolyte internally. It is in charge of power storage, discharge capacity, safety performance and life. All aspects have improved, but sometimes even surpass the ternary lithium battery in terms of price. Gel batteries can be used in the temperature range of -40°C to 65°C. The low temperature performance is relatively good, and it can be used in the northern alpine regions. It has good seismic performance and can be used safely under various harsh conditions. The service life is double or even more than that of ordinary lead-acid batteries.
Because the solar energy of the solar street light is unstable, the energy is strong during the day but no energy is provided at night, and the solar street light needs to work at night, so the solar street light system needs to be equipped with a battery.

In summary, solar street lights use lithium iron phosphate batteries, of course, but the price is higher. At present, the solar street lights on the market use lithium iron phosphate batteries with reasonable prices. This product uses a lithium iron phosphate battery with a lifespan of up to 10 years. The price is very attractive. Interested consumers can understand .
However, the battery is the core part of the solar street light after all, so you must understand the manufacturer’s after-sales and technical assistance when buying, and personally recommend Bbier Lighting for you.Bbier Lighting Company has a variety of styles of solar street lights, solar lawn lights, and solar mushroom lights. They all use high-quality battery equipment and have a 5-year warranty. Welcome to buy.

A Detailed Guide : How do I make my solar led garden lights brighter?

 Switching to outdoor solar led garden light is a grand idea. You can use the power of the sun to illuminate the yard at night without having to spend electricity bills or worry about forgetting to turn on and off the lights. The price of solar lighting has gone from being truly affordable to quite expensive, and those who have owned them for a while may have noticed that their illuminance is not as high as before. Is there anything that can be done about that?

Why is the solar led garden light dimmed?

How do you make your Solar LED Garden Lights Brighter in many steps will commence with you crossing off the main possibilities/reasons your solar lights may be dim or show restricted light flow. After crossing off the probable likelihoods that could be at the root of the problem, you can try opening the panel up and alter it from the inside. The last step if the light still seems defective will be to seek support. The steps are as follows:

• Step 1 – Check it’s Activated

It sounds simple, but don’t be ashamed, we have all bought things and haven’t pulled the straps from or from the battery. This is a very human error, but if your solar light doesn’t seem to work properly at all, please troubleshoot this error first.

• Step #2 – Check You Have Proper Batteries & No Corrosion

The working method of outdoor solar lights is to collect solar energy through panels and solar battery packs. These are petite batteries with LED bulbs (light emitting diodes). Due to age and environment, solar lights usually work overtime and lose their brightness, which is very common.

Whether your lamp is an old battery from the solar energy itself, or a new one-the battery may be the problem. Batteries are often corroded or tarnished. Since the battery is indeed the most important part of the device, it is necessary to equip the solar panel with an appropriately functional battery.

This may be a corroded battery, which consumes energy faster than it should, in this case, you need to remove the battery.

• Step #3 – Check the Lenses and Panels

Check every part of your solar led garden light. You will be able to see if it is dirty or has accumulated debris.

This buildup of debris may look harmless enough and like standard wear and tear for any of your outdoor belongings.

However, the factors you need to consider and their impact on the vitality/brightness of the solar light are as follows:

1.Your light is covered by dirt, which means that the sun’s rays cannot reach the panel
2.The panel does not absorb light, so there is nothing in the battery
3.Due to obstructed light during the day, it cannot be operated at night
4.Just like the dark night sky stars that we used to hang on the ceiling of the bedroom, if they don’t have enough light, they won’t shine.
5.Dirt will prevent your lights from glowing brightly, so good cleaning is required.

How do I make my solar led garden lights brighter?

• Make sure that the solar panel is getting enough sunlight during the day

This is one of the most common reasons why solar garden lights are not as bright as before. This is because solar panels do not have enough sunlight during the day. It may have been working for a few months, but now the trees and plants have grown, and something may be blocking the panel.

Therefore, in the daytime, please ensure that the panel is exposed to direct sunlight. The more sunlight on the panel, the longer and brighter the light during the day. You should make sure that the panel is receiving sunlight during the hottest part of the day.

• Cleaning the Solar Panel 

Another reason why solar garden lights may no longer be bright. It may not be clean. Even if the panel is in the sun throughout the day, if there is dust on the panel, it will not be able to get sunlight. The dust blocked the sunlight.

This is why solar panels should always be kept clean. Moreover, you need to clean it regularly. To ensure that the panel is always clean and properly charged. Then, your light will shine again.

• Replace the solar power batteries

Over time these solar power batteries are getting broken as well. They just don’t charge anymore, no matter how long you are charging the batteries. And, this will require you to purchase new batteries for the solar garden lights. Then, you will see that the lights are shining bright again.

• Consider purchasing higher quality solar garden lights

Now you know how to make your solar led garden lights brighter. These are simple cleaning techniques that may affect the brightness of the flashing lights. You should start with the solar panels and work down gradually to make sure everything is clean and in good working order. If there is no other effect, the lamp may need to be replaced to improve quality.

You should consider purchasing higher quality solar garden lights. The higher the quality, the brighter it will shine. And, it will make sure that you are getting the results that you were hoping for.

Conclusion

There are many things you can do to brighten up your solar led garden lights, especially when we talk about items that you have owned and used for a long time and are likely to be dirty. Solar led garden lights are exposed to various environmental factors, not to mention pollutants (such as dust and debris). Generally speaking, solar lights are low-maintenance products, but this does not mean that you don’t have to clean them regularly. Otherwise, you will find that the light fades much more than when it was first installed.
