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.

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.

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.

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)

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.

Do not last


I use these bulbs in my kitchen, living room and office. Absolutely love the way they brighten up the room. My kids do their homework in the kitchen and these bulbs provide great lighting for reading and writing; same for computer use in the office. I bought 16 of these bulbs in February 2012 and as of today, 7 have already popped. Some popped within 3 months use, some within a year and some within 2 years. That's more than a 40% failure rate in a span of 2.5 years. You will not get 12,000 hours out of these bulbs so consider this and the cost before purchasing.

Very fast response


We ordered these are a replacement to our lighting booth. We ordered 100 bulbs to replace the old bulbs before they went out. Great price by over half and they came in fast.

You get what you pay for.


The first group I purchased two years ago lasted almost two years. The group I purchased in the spring of 2013, most have burnt out in 6-9 months.

Excellent item


Great, bright light.




Great Bulbs!


These high (K) bulbs are the only way to go. Our home was using low (K) bulbs for years, we really didn't know the difference, the only thing I did know was that CFL bulbs were horrible, ie. dim/yellow glow. After some research, and discovering that we knew nothing about CFL lighting, it became evident that we were using the wrong ones (for YEARS). I guarantee if you use these high (K) bulbs, you will never go back to standard light bulbs again. Also, do some checking----you won't find better bulbs/prices anywhere else. Thanks have my business.




I would buy this product again!


Love these bulbs. Had searched the "box stores" and could not find the 26 watt bulbs anywhere. Will order again when needed.
