LED stands for Light-Emitting Diode. LED bulbs produce efficient, visible light when an electrical current passes through a semiconductor device.


It may sound complicated but they’re really quite simple, just highly specific in regards to your taste in brightness and color.

Traditional Incandescent Produce light when electricity is passed through a filament. Once the filament reaches a certain temperature it glows. About 90% of their energy is released as heat.

CFL An electric current is passed through a tube containing gases. The reaction produces light via the fluorescent coating on the interior of the tube. Contains mercury. About 80% of CFL’s energy releases as heat, and are slightly more efficient than an incandescent. The design provides two main drawbacks, the light takes a while to reach full brightness and the small amount of mercury is harmful to your health and the environment upon breakage and disposal.

LED Tiny light emitting diodes are illuminated through a semiconductor material via the movement of electrons. The small amount of heat produced is released into a heat sink. LEDs are generally cool to the touch and do not contain toxic cases.


Kelvin Is a unit of measure for the color temperature of light sources. At the lower end of the scale the color temperature is warmer and emits a soft and inviting ambiance.  The higher the degree, the light will appear cooler. Though a cooler tone may appear brighter, brightness is not affected by the color temperature.

Lumen A lumen is a unit of measure for the light intensity or brightness from a light source. For LEDs you should shop based on lumens, not watts. Watts measure the amount of energy used (watts are drastically lower in LED bulbs). General Rule: The higher the lumens, the brighter the light that is emitted.


Power Consumptions/Energy Savings:

LED wattage is the measure of electricity the bulb consumes. LEDs can deliver the same about of light (measured in Lumens) as traditional incandescent and CFL bulbs, but use far less wattage.  For example a 60 watt equivalent with 800 lumens, may use as little as 9 watts! The lower wattage number equates to a cost savings because the LED bulb is using less electricity to light up your home than incandescent and CFL bulbs.



A series are similar in shape to the standard bulb that you are used to, there are slight variations on shape and size in the A series

A19 is comparable to a standard light bulb. Ideal for use in table lamps, floor lamps, pendants, ceiling fixtures

A21 bulbs are slightly larger than the A19 to allow for higher lumens (brightness)


BR bulbs have a ‘frosted’ and curved lens to reduce glare and evenly diffuse light

BR30 are most ideal for track lighting, recessed can fixtures, or floodlights

BR40 bulbs are slight larger versions of the BR30


PAR series bulbs refer to the general shape as they do not need the reflector of more traditional bulbs due to the directionality of the LEDs. The lens on PARs are flat and textured.

PAR38 are ideal for security lights, flood lights, and outdoor use to amplify and concentrate light


CRI stands for Color Rendering Index. This scale indicates the accuracy of color from a given light source. The higher the number on a scale of 0-100, the more accurate and true the color of objects will appear to the human eye.



Beam spread measures the spread of light from a light source in degrees. For example, a light with a beam spread of 45 degrees casts light within a wedge of 45 degrees, providing a more focused light in that range. An omnidirectional bulb casts light in all directions.




Omni Directional The light is spread out in all (omni) directions, allowing for wider coverage. The pattern of light allows for an output of 270-300 degree angles.


Our dimmable LED bulbs are compatible with traditional dimming switches. Non-Dimmable– the bulb is not capable of dimming.


LED bulbs create heat but generate far less than their incandescent and CFL counterparts. LED bulbs are designed with as heat sink built into the base of the bulb that wicks heat away from the light source allowing for the LED bulb to be generally cool to the touch.




The average LED bulb typically lasts for approximately 25,000 hours which equates to 22.8 years! The long lasting life is achieved when used in a residential setting for an average of 3 hours per day. Most manufactures claim CFLs have an average span of 10,000 hours (9 .1 years) and traditional incandescent bulbs have an average lifespan of 1500 hours (1.4 years).
