How are LED lighting products different from other lighting, like fluorescent or incandescent?
LED’s are small, solid light bulbs which are extremely energy-efficient. The VIRIBRIGHT LED light bulb is made up of clusters of LEDs (light emitting diodes) that illuminates beyond traditional incandescent bulbs or CFL bulbs while using much less energy. Until recently, LEDs were limited to single bulb use in applications such as instrument panels, electronics, pen lights and, more recently, strings of indoor and outdoor Christmas lights. Now available with standard bases which fit common household light fixtures, LEDs are the next generation in home lighting as well as a cost-effective means of lighting your environment.
What is the voltage requirement for VIRIBRIGHT?
100V – 240V
How much power does VIRIBRIGHT LED Light Bulbs consume?
11 Watts for 60 Watts of light
8 Watts for 50 Watts of light
5 Watts for 60 Watts of light
What are the Color Temp Kelvins for VIRIBRIGHT?
The unit Kelvin is an indication of the light color. A typical light bulb is about 2,500K. A CFL warm white is about 3,500 - 4,000K and CFL cool white is 5,000 – 6,000K. The VIRIBRIGHT LED cool white is 5,600-6,000K and the warm white is approx. 2,900K.

What is Color Rendering Index (CRI)?
The CRI indicates how true the color of an object is when placed under direct light. The CRI of the VIRIBRIGHT LED cool white is 0.80 and the warm white is 0.65. In comparison, the CRI of a normal light bulb is 1.
What type of plastic is the cover made out of?
The transparent cover is made of Polycarbonate. Polycarbonates are a particular group of thermoplastic polymers that are easily worked, molded and thermoformed that are temperature resistance and impact resistance
What is the material used for the base of the bulb?
The heat-sink base is made of aluminum; the screw cap is made of chrome plated copper.
Why does the VIRIBRIGHT bulb top stay cool to the touch?
LED lighting products use light emitting diodes to produce light very efficiently. The movement of electrons through the semiconductor material illuminates the tiny light sources we call LEDs. A small amount of heat is released backwards, into a heat-sink, in a well-designed product; LEDs are basically cool to the touch.
Can the VIRIBRIGHT bulb be disposed of safely?
As a matter fact, yes they can, unlike CFLs that contain mercury and have strict disposal laws, VIRIBRIGHT LED bulbs can be safely disposed of with no worries of contaminating the environment.
Does the VIRIBRIGHT LED bulb conform to safety standards?
VIRIBRIGHT conforms to ETL, UL, CSA safety standards.

Are there any frequency issues or concerns (FCC)? We noticed on a few LED packages from other manufacturers that they had a warning about interference.
The interference tests are included in the ETL, CE and UL tests.
Why is the lifespan of an LED measured as lumen depreciation?
The lifespan of an LED is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally lasting 50,000 hours or longer. Although the LED never really burns out, product lifespan is measured by lumen depreciation.
The Illuminating Engineering Society (IES) currently recommends calculating the life of an LED at the point at which the LED reaches 30 percent lumen depreciation.
Remember, a 50,000-hour rating is not equivalent to lamp life rating. LED life is rated where it has reached 30 percent lumen depreciation. At 50,000 hours an LED would still be operating, but at a decreased lumen output.
How long is 50,000 hours?
Based on how long a fixture is illuminated per day, here’s what 50,000 works out to:
Hours of Operation: 50,000 hours is:
24 hours a day 5.7 years
18 hours per day 7.6 years
12 hours per day 11.4 years
8 hours per day 17 years

Is there a ban on incandescent light bulbs?
Countries all over the world are beginning to ban incandescent light bulbs. U.S. Congress has passed a bill that will begin the phase-out of incandescent light bulbs in the U.S. beginning with the 100-watt bulb in 2012 and ending in 2014 with the 40-watt bulb. All light bulbs must use 25 percent to 30 percent less by 2014. By 2020, bulbs must be 70 percent more efficient than they are today.
What are the advantages to using LED lights?
LEDs bring several advantages to the lighting industry, including high efficiency and durability, and, with superior life
over other lamp sources; their required maintenance is greatly reduced. This translates into energy savings,
maintenance savings and an overall reduction in cost of ownership over the product’s lifetime.
- Long-lasting – LED bulbs last up to 10 times as long as compact fluorescents, and far longer than typical incandescents
- Durable – LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. LEDs will not shatter.
- Mercury Free – no mercury or other hazardous materials are used in the manufacturing of LEDs
- Disposal - VIRIBRIGHT bulbs can be disposed of safely
- More Efficient – LED light bulbs use only 2-11 watts of electricity (1/3rd to 1/30th of Incandescent or CFL) and these bulbs last for years so energy is also saved in maintenance and replacement costs.
