Bay lighting is installed on high ceilings and illuminates large areas such as warehouses, buildings, exhibition halls, train/bus stations and sports centers. As bay lighting is used with a high-ceiling building which can provide high brightness while reducing glare.
Bay lighting can be categorized as low bay and high bay- differences by their installed ceiling height. Low bay fixtures are suitable for ceilings 12-20 feet high whilst high bay fixtures for 20-45 feet high. Installation could be another distinguishing way- low bay fixtures are mounted by chains and hooks for suspension. High bay fixtures can either be suspended from ceiling by using hooks, chains or pendants, or surface mounted to the ceiling depending on the fixture design and structure of the facility.
Area light is commonly used for exterior lighting, such as parking lots, street lighting, sidewalks, industrial parks and building grounds. Area light can refer to many different types of light which are defined by different light distribution- below as 5 types of light distribution for different usage.
The type I distribution is great for lighting walkways, paths and sidewalks. This type of lighting is meant to be placed near the center of the pathway. Type I is a two-way lateral distribution- two principal light concentrations are in opposite directions along a roadway. The type II distribution has a slightly wider area of lighting distribution, suitable for wide walkways, on ramps and entrance roadways. This type is meant for lighting larger areas and usually is located near the roadside. The type III distribution is meant for roadway lighting, general parking areas and other larger areas of lighting. Type III lighting needs to be placed on the edge of the area with its linear directional light pattern. The type IV distribution produces a semicircular directional light pattern. It is ideal for security lighting meant for mounting on the sides of walls, also suitable for illuminating wider walkaways. Type V produces a full 360-degree lighting distribution with equal lighting distribution at all angles which can also be designed as a square pattern. It has to be placed in the center of the area, for example in commercial parking areas and intersections.
Haven’t you made up your mind to change to LED? LED lighting is beneficial from an economic and environmental perspective. The “Green” concept has become common as well as the pursuit of carbon neutral. The lifetime is much longer and the efficiency is much better when compared with LED lighting and traditional lighting ways.
Speaking of outdoor lighting, efficiency and longevity are the most important factors to be considered. LED lightings are estimated to sustain more than 15 times longer than traditional ones. However, the energy fee of LED lighting is 70% less. Needless to say, how big a difference it is when speaking of the decrease of CO2 emission- beneficial for the globe.
It is also a great idea to change indoor lighting to LED ones. Enjoy the ambience and varieties of lighting options with LED lighting. Unlike traditional ones, LED lighting is an electrical device which provides many functions- color temperature adjustment, lighting color, dimming, movement sensor and timer etc. Adopting LED lighting elevates quality of life and improves mood while living and working.

Since Traditional HID Lighting Evolving into LED Lighting, we have moved into a electronic component sector today, so what that means is that the longevity of these product are highly dependent upon the thermal dissipation and how the electrical component can operate over a duration of period.
With LED chips and power supply, it is important to operate them at a requested operating temperature (as provided by specification) if operate above the said operating temperature, it means the components are now taking on more heat than it is designed for. This in terms can cause early life failure for some of these components.
Therefore, an LED Lighting which is designed to ensure the proper thermal heat dissipation is so important. Many manufacturers, when assembly LED Lighting Fixture, might not go through a proper aging test, this is very critical in the part of quality assurance for product.
Aging test, which means powering the LEDLighting Fixture for a duration of period, to Identify how the fixture is operating, in terms of its thermal and functional aspect. Aging test is critical, in detecting early life failures, whether it be poor soldering in power supply or LED PCB board, or simply identifying a higher operating temperature than originally designed.
All our LED lighting conduct through 4 Hours of Multiple voltage aging test, to identify any product which may cause early life failure, prior to shipping. It’s important in doing so to eliminate the faulty Products and prevent it from getting to the hands of the consumer.
Aside from aging test, there’s also alternative more intensive testing, like the HALT Testing (Highly Accelerated Lifetime Testing) where a harsh external environment is created to speed up the proceed of LED lighting. This Is important in the development stage of the product.
For more information on the various type of testing done on lighting to ensure quality and longevity, contact us today.
As LED lighting been rapidly adopt in commercial and industrial application in the past 10 years. Based on our customer’s feedback and our own evaluation:
It is known by fact that lower LED temperature increase the luminous efficiency LED, therefore a good heat dissipation of LED is very important. When LED driver is installed in the light fixture’s structure. A higher efficiency LED driver consume less power for converting AC power into DC power. Therefore, it will emit less non-useful power inside the lighting fixture, thus reducing the temperature rise of lighting fixture. By doing this we can maintain the light output and reduce the negative impact because of higher temperature and extend LED light’s lifetime.
especially like the led driver of LED Flood light, generally they are installed outside, of course, maybe separate from the light fixture as well. such as hidden in the light pole or installed on the fixed bracket. We must comprehensively think of its waterproof, aluminum housing and any other performances. High reliability led driver is not easy to break and help to reduce the cost of maintenance.
High power factor
For commercial and industrial outdoor lighting, it is very common for lighting manufacturer to registered product with Design Lights Consortium. One of the requirement for Lighting Fixture certified as DLC listed is power factor must large than 0.9. The power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1. In an electric power system, a load with a low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment the power factor is the load requirement of the power grid and is an important technical data of power system. Therefore, we only use LED driver with power factor higher than 0.9.
Constant Current and Constant Voltage driving methods.
It is common to see there are two type of LED driving method, one is Constant current and the other one is Constant voltage, what make it difference is the way in which they deliver the power. LED drivers are the main driving force that provides and regulates the needed power to make sure the LEDs operate in a safe and consistent condition.
Constant current LED drivers are designed for a selected range of output voltages and a fixed output current. Constant current driver requires a designated supply of current usually specified in (mA) or (A). These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the LED system. Higher current ratings do make the LED brighter, but if not regulated, the LED will draw more current than it is rated for. Thermal Runaway refers to excess current beyond the LEDs maximum drive current which results in drastically lower LED life-spans and premature burn outs due to increased temperature. A constant current driver is the best solution to drive high power LEDs as it maintains a consistent brightness across all LEDs in-series.
Constant voltage drivers are designed for a single direct current (DC) output voltage. It is quite common to have an 24VDC or 36VDC. An LED light that is rated for constant voltage usually specifies the amount of input voltage which needs to operate correctly. A constant voltage power supply receives standard line voltage. For USA’s residential application, it is usually 120V AC to 277V AC. This is the type of power that is typically output from the wall outlets in the home. Constant Voltage Drivers switch this alternating current voltage (VAC) to a low direct current voltage (VDC). The driver will always maintain a constant voltage no matter what kind of current load is put on it. Most often, constant voltage drivers are implemented in under-cabinet lights and other LED flex strip applications but it is not limited to those categories.
It sometimes called as surge protector, it is an indispensable device for electronic equipment to protect against lightning or surges. The function of the surge protector is to use components such as gas discharge tubes or varistors to discharge the transient over voltages such as strong lightning or surge currents into the power or signal transmission lines into the earth, limiting the voltage range of the equipment or system within the range that can withstand, the protected equipment or system will not be damaged by the electric shock (voltage surge). It is very common for outdoor lighting driver to have build in minimum 4kV surge protection.
One of the most common lighting failures, is the surge spike resulting in driver IC in the fixture to get damaged. So how does surge spike occur and how can we prevent it from damaging our lighting fixtures?
Most of the time one of the most common occurrence is due to regional voltage in spike, causing a sudden spike in the current going through the electrical circuit in the area. If the electronics or the LED lighting fixture does not provide sufficient enough surge protection, you are looking at an early life failure for that product.

With some construction work on job-sites, working the car in the garage, or simply a need to light up our Backyard, a work light comes in handy, but seeing so many different types in the market, how do you know what is the right one to choose and what to avoid?
You might see a lot of work lights in home centers, with some with a lot of features and some just simply such low cost, we’ve compiled a few pointers when choosing work light to help you avoid stepping on potential landmines.
Aluminum vs Plastic-Which one to choose?
With more and more plastic housing work light in the market now. It offers a much more cost competitive solution. If you just want some temporary light source that does the job, and not looking to spend an arm and leg, simply buying a plastic work light is fine for you. However, there are few things you should remember:
1. Plastic generally have a poorer dissipation than aluminum, therefore with some work light that offers up to 50-100W, plastic simply unable to dissipate such heat generated, meaning could cause early life failure. If a work light only runs about 10-20W(1000-1500lm) or so, there is not much heat generated from the LED therefore plastic is an acceptable option. However, if you are looking for some of those larger fixtures, Aluminum Die-Cast Housings offers optimal heat dissipation, to allow your fixture run for much Longer duration without overheating.
2. If this work light have the chance to be left out in the sun for a longer duration, then plastic may not be the right choice. As plastic tends to become more fragile or easily crack after long period of UV exposure, having it in the sun doesn’t do too good for the product. Plastic also have a tendency to change color after a period of exposure to the sun. Aluminum work light on the other hand, do not have the issue of becoming more fragile after sun exposure.
3. Plastic housings are generally made via plastic injection, where the plastic pallets from time to time can be recycled. Generally seeing the with lower cost plastic work light in the market, could correlate to poor quality plastic(higher percentage of recycled material) which in the long run, effects the quality and performance of the product as well.
For more heavy duty, long duration, high lumen application, it is still recommend to use aluminum Type work lights. Whilst from price aspect may be slightly higher than plastic, can guarantee in terms of durability it will last you a lot longer time.

How often when you driving past residential area, when you see paint peeling off poles, walls, lights fixtures? Does not look pretty right?
Whilst paint peeling on commercial and residential lighting fixtures can occur more in areas with high air salinity (Florida and areas near ocean)
It’s important to know that It is not main cause for paint peeling.
What if we told you that paint peeling is something that can be easily avoided, through the right choose of powder coating material and correct treatment process during production. If done properly, The light fixture’s paint should last 10 years or more without any discoloration or peeling.
When commercial/residential lightingfixtures such as Floodlights, Area Lights, Wall packs are manufactured, especially The aluminum base Fixtures, generally prior to applying the Powder Coating process, a lot of Fixtures don’t go through the proper surface treatment of the aluminum or Metal Parts. As with a lot of these aluminum fixtures, during production there is generally a layer of dirt/oil/Aluminum scraps or other substances found on the surface of the parts, If you don’t remove these, when you apply PowderCoating onto the Fixture, the layer of substances between the Aluminum Metal Parts and the powder Coating, will prevent the Coating to become fully adhesive onto the these Parts.
Over Time, When Lighting Fixture is exposed to UV, combine with the coating not being fully adhesive onto the LightingFixture, it causes the Paint to become detached from the surface of the Fixture, causing the Paint to Peel.
By knowing this, This is why we takes this matter very serious, and go through additional steps on their Lighting Fixtures in preventing the Paint from Peeling over time. All of First Lighting Fixtures go through a process which we call Pre-treatment Process. This Process applied during the assembly of Fixture, where all the Aluminum/ Metal Parts prior to Coating Process, we place these parts into Pools of cleansing agent to remove any excess and unwanted dirt or oily substances from the surface. Doing that is not enough, we then move the parts into a pool of Zinc Phosphate, and what that does is it adds an additional icoated layer onto the Aluminum Parts, so that when you implement Powder Coating, it allows Coating to become fully adhesive onto the surface, increasing the durability of the Paint.
Furthermore, we choose only the Best PowderCoating, a high UV resistance Powder Coating, to ensure the longevity and prevent any discoloration over a long duration use (tested for hundreds of hours in our Lab).
Our Goal is to ensure the longevity in our lighting product, whether it be performance or aesthetic appearance, which is why when choosing Ascent Technology, you can feel confident knowing the process we go through in making our lights.
