LED (Light Emitting Diode) is a tiny semiconductor encapsulated in plastic which emits light when an electric current is passed through it. The material used in the semiconducting element of an LED determines its color.
LED lights come in a variety of models:
SMD refers to “Surface Mounted Device” The LED chip is permanently fused to a printed circuit board, and it’s highly popular due to its versatility.
COB refers to “Chip on Board” Like the SMD, COP chips also have multiple diodes on the same surface. But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB LED lights can’t be used to create colour changing bulbs or lights.
Light emitting diodes produce light by the movement of electrons between the two terminals of diode, which occur by a process called electroluminescence. When a light emitting diode is electrically connected, electrons start moving at the junction of the N-type and P-type semiconductors within the diode. When there is a jump over of electrons at the p-n junction, the electron loses a portion of its energy. In regular diodes this energy loss is in the form of heat. However, in LEDs the specific type of N and P conductors produce photons (light) instead of heat. The amount of energy lost defines the color of light produced.
They are more robust than other light sources because they don't get very hot like regular light bulbs and they don't have a filament that will burn out and no moving parts to fatigue. There is no glass to break or screwed contacts to loosen.
LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!

SMD means surface mounted diode. This is a better technology than the first generation DIP LEDs. The SMD type LEDs are mounted on an aluminum substrate and enveloped in an epoxy resin.
Measurement of luminous flux of quantity of light emitted by a source. In simple terms, Lumens (denoted by lm) are a measure of the total amount of visible light (to the human eye) from a lamp or light source. Higher the Lumen, the Brighter the Light.
Luminous efficacy is a measurement of how effective the light source is in converting electrical energy to Lumens of visible light. Usually expressed in Lumens per watt (L/W). In more simple words - how well light source turns input power into the desired output/light, which is lumens.
Power efficiency is reported in percantage, it is the actual percentage of power in which comes out as photons.
Wattage measures power or energy use but with low-wattage, energy efficient LED lights buying bulbs based on watts has become less prevalent. So while we may be accustomed to shopping for bulbs according to wattage, lumens are actually a more accurate measurement of how bright your light will be. Measuring and labelling light output instead of energy use makes it easier for you to find the right energy efficient bulb for your space. For example, if you typically purchase 60W incandescent bulbs, which produce about 700-800 lumens a 10W LED light might be equivalent to achieve the same brightness.
Color Rendering Index (CRI) is the measurement of how colors look under a light source when compared with sunlight. The index is measured from 0-100, with a perfect 100 indicating that colors under the light source appear the same as they would under natural sunlight.
Unit of luminance or density of light falling onto a surface. One Lux is equal to one lumen per square meter.
Color temperature is measured in Kelvin degrees and they are typically denoted by a numerical figure followed by the letter “K”. In Kelvin scale lower values equate to warmer light colors and vice versa.
Size of the cone of light produced by lighting source measured in degrees.
IP is an acronym "Ingress Protection". It is a measurement of the protection an item will have against solid objects (dust, sand, dirt, etc.) and liquids.
Each IP rating has two numbers, both of which give you information about the protection level. A higher number means greater protection against solids and liquids.
- The first number (0-6) refers to the level of protection against solid objects and moving parts, such as dust, debris, or other solid matter.
- The second number (0-8) references the level of liquid and moisture protection.
Low IP ratings are appropriate for:
- Indoor use
High IP ratings are appropriate for:
- Unsealed outdoor locations
IP65 = Water resistant. “Protected against water jets from any angle” *Do NOT submerge IP65 LED lights, these are not waterproof.
LEDs are driven by constant current (350mA, 700mA or 1A) drivers or constant voltage (10V, 12V or 24V) drivers.
Constant current drivers fix the current of the system and vary the voltage depending on the load of the LED.
Constant voltage drivers require a fixed voltage, and the LED loads are added in parallel across the output of the driver until maximum output currents are reached.
First and foremost, LEDs are not dimmed based on an increase or decrease of voltage (as is the case with their incandescent counterparts.) Light gets emitted from a semiconductor chip, so it’s either on or off, and the LED will maintain its operation at the same voltage and current level as if it were operating at full light output.
Instead, what the LED does is it creates a “dimming effect.” There are two ways to do this: pulse-width-modulation (PWM LED) and analog dimming (sans cool-sounding acronym.)
PWM dimming involves switching current at a high frequency from zero to the rated output current. CCR dimming: The lighting level required is proportional to the current flowing through the LED. Current flows through the LED continuously and is reduced or increased based on whether the LED is to be dimmed further or made brighter.– LINK TO DIMMABLE LIGHTS, LINKS TO DIMMABLE DRIVERS
Saves energy, because less energy is used for reduced output levels.
Extends life; the electronic components run cooler. This not only extends the life of LEDs but also increases the life of the phosphor coating that is used to produce white light.
Helps designers create ambient lighting presets to create mood settings.
Increases flexibility in usage of space. A brightly lit space for reading or an office space can turn into a presentation/conference area by dimming.
Increases productivity by enabling individual control of lights in order to reduce eye strain and fatigue, or to improve concentration.
High bays are designed to be used in very high areas (approximately 6m and greater) to provide well distributed and uniform light for open areas. The key element of the fitting which will help guarantee the correct light output is the reflectors and optics used by the fitting. A particular consideration for use with a high bay is if it can light vertical surfaces as well as it can illuminate the floor, or working plane. Lighting of verticals is particularly important when dealing with warehouses where items are required to be picked from a shelf.
A lamp that provides a broad beam intended to light a general area.
Tri-proof (lights) refers to anti-corrosion, dustproof and waterproof. They are widely used in food processing factories, dust free clean-rooms, production workshops, parking areas, pharmaceutical factory lighting solutions or replacement to traditional T5/T8 fluorecent lamps. Ideal for a variety of industries and farm lighting solutions.
Light source set in a metal cylinder and mounted or recessed into the ceiling so the beam of light is directed downward.
A lamp that produces a narrow beam angle designed to illuminate a specific targeted area.
Track lighting is a method of lighting where light fixtures are attached anywhere on a continuous track device which contains electrical conductors.
TÜV is a single testing and certification source for all types of lighting products. Ensure high quality and conformity with TÜV standards.
UGR (Unified Glare Rating) is a method of calculating glare from luminaires and it helps to determine how likely a luminaire is to cause discomfort to those around it. For example the discomfort that a LED Panel will cause the work force within an office. Inappropriate luminaires cause excessive brightness to be “bounced off” reflective surfaces, such as computer screens, whiteboards etc. Within an office setting, for the luminaire to be classified as “low glare” it must have a UGR below 19 at desk level. Anything above this may cause discomfort – this further enforces the need for high quality interior lighting that is rated UGR<19.
Correlated Color Temperature (CCT) Changing panels is LED lighting solution that change from warm white to cool white light. Color Temperature Changing panels in your office, home, or school can effectively improve mood, productivity, and aesthetics, decrease risk of disease, increase property value, all while saving money and becoming your property more sustainable!
Acronym for Red, Green, and Blue and White. Red, green and blue are the 3primary colors of light and combinations of these 3 create wide variety of other colors which is possible with our RGBWW LED panels. White means that you can also use the panel as white and change the white colour from warm to cool and you can also dim those panels – choose the brightness level.
You need to cut the power and make sure everything is safe in order to begin your work on the lights. And under no circumstances should you ever turn the power back on while you’re still working on the lighting.
The light panels are easy to install. You can install these light either:
- without any extra accessories or tools to metal grid system ceilings
- with mounting clips to suspended gypsum ceilings
- with our surface mounting panel light frame to concrete surfaces
- with suspension kit for different surfaces for hanging from the ceiling
All you have to do for each method is make sure that they have a power wire running to them.
Those combinations refer to bulb fitting sizes. E27 is the screw holder whose diameter is 27mm, E14 is the screw holder whose diameter is 14mm. GU: “G” standS for that the lamp holder is "plug-in" type, “U” stand for U-shape, and “figures” behind “GU” diameter millimeter.
The letter “T” will stand for tubular shape and the number will tell you the bulb diameter in eighths of an inch. T8 will have one-inch diameter / 2.54 cm in diameter. Both T12 and T8 lamps use the medium bi-pin base, which allows T8 lamps to fit into the same luminaires as T12 lamps of the same length.
Human and insect eyes are different, many types of insects have trouble perceiving light with a lower color temperature. From our selection you will find bulbs with warm-colored yellowish LEDs which are very unattractive for different insects. Yellow bug light works by shifting the color temperature of the light further left on the spectrum to a point where it is nearly invisible to many flying insects.
