LEDs, or light-emitting diodes, are semiconductor devices that produce visible light when the voltage is applied to them. Compared to traditional light sources, LEDs bring many advantages including higher efficacy, longer lifetime, instant-on, greater optical control, greater design flexibility, is dimmable and contains no mercury.
This translates to energy savings, cost savings and environmental sustainability. For further information about LED technology, check out the US Department of Energy. (Link)
LED lamps offer a great array of benefits when compared to CFLs and other energy saving lamps.
Among the benefits offered by LEDs we found:
- Instant On: LED lamps to turn on instantly at full brightness with no prior warm-up required.
- Mercury Free: Absent of any amount of Mercury (Hg).
- Lead-Free: Absent of any amount of Lead.
- Cool to the touch: Unlike incandescent bulbs or CFLs, LEDs transmit heat downwards releasing such heat to the heat sink (body) and allowing the diffuser (head) to be cool to the touch.
- Shatter Resistance: Most LED bulbs are shattering resistant thanks to their plastic diffusers which avoid inconvenient dispersion of cutting material.
- Long Lasting Durability: Unlike incandescent bulbs and CFLs, LED products to count with a durable and constant performance that ranges from 25,000 – 50,000 Hrs. of continuous use.
- No Flickering
- Dimming Options
- No UV rays emitted
- No Bug attraction
- Energy Efficient
- Flexible Multi-Purpose Design
- Low Maintenance Cost
- Environmentally Friendly
It is the total quantity of light emitted in all directions and measure by lumens (lm)
Lumens (lm) are a measure of the total amount of visible light (to the human eye) from a light source.
A Watt is a measure of electric power.
The angle of the light emitted by a light source. Directional lamps are considered “Spot” (when the beam angle is ≤22°), “Flood” (when the beam angle is >22° and ≤45°),
“Wide Flood” (when the beam angle is >45° and ≤90°).
The measure of the luminous flux density falling on a surface
Refers to the light intensity produced by a light source often located at the center. Its measurement unit is candela power (cd)
Measures the efficiency of a light source by diving the total lumen output (lm) with the total input power (W).
The correlated color temperature (CCT) is a specification of the color appearance of the light emitted by a lamp, relating its color to the color of light from a reference source when heated to a particular temperature, measured in degrees Kelvin (K). –Rensselaer Polytechnic Institute
“Warm White”, “Soft White”, “Bright White”, “Cool White” and “Daylight” refer to different (CCT) Correlated Color Temperatures produced by a light source.
Although the most accurate and proper manner to analyzed CCTs is through (K) Kelvins some people choose to use terms such as warm white to differentiate various CCT Values. This manner was adopted originally from CFLs when they were introduced to the market.
A color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. -Wikipedia
True Color described Euri Lighting products that contain a higher CRI level mostly in the 90+.
Lux is the unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre.
Most Euri lighting lamps offer an estimated 25,000 Hrs. long lifespan. On the other hand, Euri Lighting downlights offer 35,000 Hrs. estimated lifespan and high power downlights offer 40,000 Hrs. of estimated lifespan.
In 2014 on 1st July new legislation for Part 6 of the 2013 Building Energy Efficiency Standards came into effect in the form of California Title 24. It covers the energy efficiency of process and controls of lighting along with other electrical equipment like window treatment and HVAC equipment for the three-year cycle. -Title24compliant.com
CFL, or “Compact Fluorescent Lamp” is a lamp that has been compressed into the size of a standard-issue incandescent light bulb.
LED Filament light bulb is an electric light bulb which produces light with a LED that is shaped as a filament.
A 3-way bulb has two filaments designed to produce different amounts of light. When in use the outcome is three different amounts of light that are activated through three phases.
Euri Lighting recommends only using dimmable bulbs in dimmable sockets and non-dimmable bulbs in non-dimmable sockets.
