Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
Energy Used
1 Watt

Incandescent/Halogen Equivalent

The wattage value of an incandescent or halogen lamp of similar brightness.
Incandescent/Halogen Equivalent
15 Watts


A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.


The end (or ends) of the lamp that fits into the socket.
Medium (E26)

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".
Bulb Shape

Bulb Color

The color of the light produced by a bulb
Bulb Color
Warm White


Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
Color Temperature (Kelvin)

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
Brightness (Lumens)

Bulb Finish

The surface finish of a bulb, which may affect the quality of the light emitted.
Bulb Finish

Bulb Technology

The technology implemented by the bulb, e.g. incandescent, halogen, LED

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
Average Rated Life (hr)

Operating Temperature (°F)

The ambient temperature in which the product can safely operate.
Operating Temperature (°F)
-5 to 110

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Length (in)

Diameter (in)

Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
Diameter (in)

Wet Location

Suitable for exterior or interior location in which uncontrolled liquid may drip, splash or flow on or against electrical equipment.

Comments about Litetronics Non-dimmable 1W 2700K S11 LED Bulb:

in working with the new age CFL and LED retrofit edison base screw bulbs,
I was already thinking out of the box about how people use light, and color and application.
like LEDs better performence, is worth the added cost, however the colors of this LED can appear outworldly, as well as being preceived as brighter than the incandesent lumen equivilent
thus light equivilent is understated, the LED may feel overly bright, so there needs to be an expanded selection of very low wattage LED products. Often in a multibulb lamp I will use one incandesant bulb to overcome the annoying time lag between when switch is closed and lamp lights. as these are being used on a dusk to dawn eye outdoors, not an issue; power consumption and long life, and only enough light to see where one is stepping in the dark, are main criteria
