|Measures energy required to light the product. The lower the wattage the less energy used.||The number of hours the product will last.|
|Measures light output. In lumens. The higher the number, the more light is emitted.||Measures energy required to light the product. The lower the wattage the less energy used.|
|The force of an electrical current that is measured in volts. The standard voltage and frequency of alternating current (AC) electricity used in homes varies from country to country throughout the world. Typically, either 110-volt AC (110V) or 220-volt AC (220V) voltages are used. Also, most countries use 50Hz (50 Hertz or 50 cycles per second) as the AC frequency. Only a handful use 60Hz. The standard in the United States is 120V and 60Hz AC electricity. However, due to fluctuations, the average measured voltage is 117 VAC.||Is a measurement of how efficiently Your LED light source in using electricity, It is defined as the ratio of working power (kw) to total power (kva). As an example power factor of 0.9 means that 90% of power supplied by the LED light source is being used efficiently and 10% is being wasted.|
|Indicates the number of years the product is warranted for.||The temperature color rating scale ranges from a warmer 2700k up to 4100k known as cool white and 5100k known as daylight. When purchasing a light bulb you can view the specifications to see what the color temp is.|
|The brightest light emitted from a LED light source is directly below it. As the light spreads, the intensity decreases. The beam angle is measured at the points where the light is emitting 50% of the brightest reading. This can be illustrated in a cone shape as shown in the diagram.||General description of what environment this product is well suited for.|
|Color Rendering Index (CRI) measures color accuracy. Color rendition is the effect of the LED light source’s light spectrum on the color appearance of objects.||Signifies the temperature range that the LED light source can operate. A major factor in the lifespan of an LED bulb is its operating temperature. Unlike fluorescent sources, cold temperatures do not impact the performance of LEDs, though higher temperatures may.|
|The E26 is the standard 120 Volt American base. The E27 is the European variant and is rated at 220 Volts. E26 is 26 mm and the E27 is 27 mm diameter. However, an E26 bulb can fit in E27 base and an E27 bulb can fit in E26 base without problem. The sockets / bulbs are interchangeable except for the voltage rating. Therefore, LED E26 bulbs that are universal line-voltage can be used in both E26 and E27 sockets.||While consumers are learning more about LED lighting, there are still many questions to be answered. Many LED products lack minimum safety, environmental and performance standards, leaving consumers unsure about product reliability. Thankfully, there are a number of recognized LED lighting certifications that consumers can rely upon.|
|UL Listed||CE Marking|
|UL (Underwriters Laboratories) is an American safety and consulting company offering services in 104 countries worldwide.
As an LED lighting certification, UL Listed means that UL has tested representative samples of the product and determined it meets UL’s requirements based on its published Standards for Safety.
|The CE mark is mandated for certain products sold within the European Economic Area, enabling freedom of movement in the European market.
This marking means that the manufactured product meets EU safety, health and environmental standards that have been stipulated by legislation. Products demarcated with CE are not necessarily produced in Europe, but the marking means they can legally be sold there.
|The CSA (Compliance, Standards, Accountability) Group is a Canadian standards development organization that accredits products to a wide range of standards certification from many different organizations. CSA marks in lighting can provide product evaluation, energy efficiency verification, test and certification, and quality standards certification for the lighting industry.
CSA markings ensure that an LED light meets certain product standards, such as energy efficiency metrics set by Energy Star. CSA is recognized by many government agencies including the EPA.
|RoHS stands for Restriction of Hazardous Substances and sets standards for electrical and electronic products. All products sold in the EU must be RoHS compliant.
RoHS Compliancy means the product does not exceed maximum levels for six restricted materials including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers.
Consumers who see the RoHS marking can be confident that their LED lights don’t contain unacceptable levels of the restricted materials listed above.
LED lighting offers many benefits and features that were difficult, if not impossible to offer with other lighting technologies. Many of the obvious benefits, such as substantial operating energy and cost reductions, longer life, and lower overall heat generation are generally well known. Another feature that allows for dramatic appearance and productivity benefits now and in the future, involves the color temperature of the light produced by LEDs.
LED Color temperature (Kelvin temperature) is generally defined as the color that the light source emits. At far opposing spectrums; light colors range from white to blue and red and more. We have all seen different color light bulbs. However even within the white color spectrum different light bulbs can range from yellower/orange white to bluer white. These different hued white lights will affect the color of the space from warmer or yellower tones to the cooler, icier blue tones.
The kelvin temperature color rating scale ranges from a warmer 2700k up to 4100k known as cool white and 5100k known as daylight. When purchasing a light bulb you can view the specifications to see what the color temp is.
There is no set rule on which color is better. It depends on the ambiance, location and purpose of the light as well of the personality of the individual(s) using the space. As a general rule outdoor spaces do better with cooler colors closer to what is known as 5100k daylight and indoor spaces seem cozier with warmer or yellower tones in the 2700k range. More modern or art deco spaces with pastel colors seem to wash better with daylight colors as compared to more traditional spaces with deep reds and blues that pop nicer with warmer colored light bulbs.
Many people prefer daylight or cool white LEDs for task or commercial spaces such as offices, garages, under cabinet lighting applications because the light does seem crisper. Most home owners, hotel lobbies and retail stores will opt for the more intimate and personal warm colors. A nice middle ground that has become extremely popular with architects in new construction is the middle ground 3500k.
