Looking at the use of light from a more practical view. Immediately, the use of cool whites and rich, warm whites and amber glows can be noticed across several scenes. The contrast use of these white shades really help set the scene subconciously for the forces of light and dark, dark and light interchangeably. Typically you&#;d imagine warm whites to be positive and cool whites to be negative, hot vs cold. But here we have a dragon as warmly illuminated and the heroes often shown in a colder light. This yin yang perspective helps to show that nothing is fully bad nor fully good. That there is light in the darkest of places and darkness hidden within the brightest lights.

So why is it that this film hits home? It would appear that orc&#;s, magicians, elves, dwarves, hobbits and even dragons don&#;t exist, at least not in this age. And yet something about this film appears so very real, as if it&#;s a memory fragment of a long forgotten past or an artistic abstraction of something quite familiar. Perhaps it&#;s the metaphysical and relatable use of light vs dark or good vs evil. The philosophical and archetypical imagery throughout this film creates a deep routed sense of awe and wonder. Whether you believe dragons existed in the past or not doesn&#;t matter. We&#;ve all faced dragons in our daily lives, greed, lust, immorality, those people that cause pain and who rarely blame themselves for anything allowing arrogance and pride to consume them. Whether within or outside of ourselves, we face chaos every day. In the words of Gandalf &#;I have found that it is the small everyday deeds of ordinary folks that keep the darkness at bay. Small acts of kindness and love.&#;

What Is COB Continuous LED Tape?
COB stands for Chip on Board, meaning the LED diodes are built directly into the Printed circuit board. The main advantage of this technology is that there is no visible spotting, even when used in more shallow LED profiles and spaces, this ensures the finished installation will present a seamless uninterrupted finish.
COB technology also generates less heat, which in turn makes it more efficient. These tapes typically run at around 100 Lumens per watt and the reduced heat level makes the tape last longer and maintain a high-level performance over a longer period of time.
This makes our COB Continuous LED Tape perfect for high-end professional and commercial installations. The high build quality and components will assure long lasting performance and reliability.
What is the difference between LED and COB LED?
The main difference between these two technologies a side from the efficiency is the way in which the LEDs are mounted to the tape.
COB LEDs are mounted directly into the circuit board with a strip over the top acting as a &#;diffuser&#; enabling a seamless finish when illuminated.
Being directly mounted to the circuit board means there is room for more LEDs to be mounted. Our COB LED tapes typically achieve 544 LEDs per metre.
Compare this to current traditional LED Tape and the use of SMD (Surface Mounted Diode) Technology, where the LED chips are mounted and secured on top of the circuit board and typically the maximum number of LEDs per metre is around 240.
The SMD version is much more likely to cause spotting and dark spots due to the spacing of the chips on the LED Tape, especially when installed into LED channel with a semi clear, or transparent diffuser over the top.

COB is the abbreviation of Chip On Board.
They consist of multiple LED chips bonded directly to a substrate to form a single module, the modules can be made into a variety of sizes and shapes.
As the individual LEDs used in a COB are chips and are not traditional LED&#;s, the chips can be mounted more densely where the highest potential of the LED chips can be obtained.
When powered, it appears more like a light panel than multiple individual LED&#;s and can include a variety of different colours, such as red or white light output.
COB LEDs have a number of advantages over older LED technologies such as allowing for a much higher packing density of the LED array which results in higher intensity, greater uniformity of light and superior thermal performance for increased life, stability and reliability.
All of these features of COB LED&#;s are great for compact flashlights, powered by a small and lightweight lithium-ion battery which can power a COB LED torch for very long periods of time.

LED lights come in a variety of types. Among them COB and SMD LED gain great popularity. And here comes the question, SMD VS COB LED, what are the differences?
*SMD LED construction
SMD LED, which is short for Surface Mounted Device LED, is the most common LED in the market. The LED chip is a versatile electronic component that is permanently fused to a printed circuit board. It is applied to light bulbs and string lights, as well as your 's notification light.
SMD LED chips are available in a variety of sizes. For example, one of the SMD chips, the SMD LED is 5mm wide while the SMD has a width of 3.5mm. As you can see, SMD chips are compact, practically identical to the flat, square computer chip architecture.
*COB LED construction
What is LED COB? COB LED technology is a recent advancement in LED lighting that allows for more effective energy use. As for COB manufacturing, it has several diodes on the same surface as SMD chip does. However, the distinction between them is that COB LED has more diodes.
Typically, COB chips feature 9 or more diodes. No matter how many diodes, they have only one circuit and two contacts, resulting in a panel-like look of COB LED lights.
When SMD VS COB LED in brightness, it also distinguishes. The level of brightness highly depends on the lumen output by the involved chips. Generally speaking, compared to other light sources, LED lights are capable of illuminating with brighter light, a result of higher lumen. But among different types of LED, the lumen differs.
For example, COB LED lumen is 80 lumen per watt at least, while SMD applies 50 to 100 lumen per watt, while the lowest measure of COB is 80 lumen per watt. Therefore, lights with COB are brighter.
In general, working with LED light like COB light ensures great energy efficiency. This is why, in comparison to filament bulbs, they are gaining popularity and becoming the most favored light source.
With this in mind, you can assured that both SMD and COB LEDs will be extremely energy efficient. But pay attention that the energy efficiency varies according to the lumens used. The higher the lumen measures, the greater the energy efficiency is.
SMD is more adaptable and offers a wider range of options when it comes to color and color temperature. It is easier to get a varied color since different primary colors can be used. When you wish to adjust the color temperature, it also works. A red, green, or blue diode could be included in the chip. You can already make practically any color with these three diodes by altering the output level.
As for the COB, however, the ability to modify the colors and color temperature is limited. It is designed to emit only one color and temperature of light. But as a result, it offers more stable lighting.
When it comes to the quality of light, it is also different when SMD VS COB LED. This is primarily due to the fact that they each use different numbers of diodes, which influences the brightness and range of lighting.
When it comes to SMD LED lights, the resulting light has a glare to it and is ideal to be utilized as a point light, a result of the attachment of multiple light sources.
COB light fixture, on the other hand, will emit a uniform and glare-free light. It produces a light beam that is homogeneous and easy to modify. This is primarily because of its wide-angle beam, which makes it a better light source. Therefore, you can DIY LED COB as surface light.
The cost of getting devices built with these different technologies differs. They are both strongly dependent on manufacturing costs, which are distinct.
When compared to its counterpart, SMD has a greater production cost. For example, SMD is more expensive than COB when comparing the labor and manufacturing process to the material cost.
Generally, the cost of SMD accounts for 15% of the total material cost. As for COB, labor and production costs contribute for 10% of the material cost for. This demonstrates that chip on board LED saves you roughly 5% on manufacturing costs.

LED lights play an important part in our daily life, especially in photography and architectural lighting. When having a purchase, SMD VS COB LED, which is more suitable? Let&#;s have a look.
In most cases, LED COB bulbs are wildly used in LED video light for photography. As we know, COB lights features luminous uniformity because of its wide beam angle, making it preferable among photographers and filmmakers.
For example, the COLBOR CL100 is a 100W COB LED light. It provides stable 100W output in bi-color temperature, enabling you to spend less time adjusting the setting. Moreover, it is incredibly light so that you can use it for mobile filming without burden. The CL100 helps you show objects in natural colors.
In architectural lighting, COB LED chips are utilized in more complex lighting applications to provide better beam angles and more aesthetically pleasing fixtures. However, SMD LED are utilized in more general lighting fixtures like diffused panel lights, which have a frosted diffuser covering the light source.
The differences in SMD VS COB LED are various such as brightness, color temperature, manufacture cost. Meanwhile, they are suitable for different applications. Just have an understanding of them and you will get an ideal LED light for video shooting and other uses.
