Model Number


Energy Used

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

Incandescent/Halogen Equivalent

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

The color of the light produced by a bulb

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)

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)

Contains Mercury (Hg)

Contains some level of the element Mercury. Typically, bulbs containing Mercury display the symbol 'Hg'.

Just OK


This bulb's warm up period seems significantly longer than a standard cfl. I orrigionally intended to put these in my kitchen which has 75 watt halogens. The bulbs didn't fit in the recessed cans. This bulb also barely dims at all. I'd say it dims from 100% to maybe 75% at the lowest. I ended up putting the bulbs in my basement which has 65 watt can lights and a few 16 watt cfls. I can't tell the difference between this bulb and the others after they are warmed up. If you put them in a fixture that fits them, has few on/off cycles, and has either 65 watt incandescents or 60 watt halogens this could be a fine solution. (Bare in mind that each bulb is [$], doesn't last all that much longer than a standard cfl, and doesn't fit in some fixtures)

Doesn't work. DO NOT BUY.


There is absolutely nothing good I can say about this bulb. should stop selling it. The first one they sent me stopped working after maybe half an hour. Dead. Won't turn on. was nice enough to ship me a replacement, but the replacement isn't much better. When I hit the lights, it barely puts out any light for the first 10 minutes. Eventually, after it warms up, it lights up the room fairly well....but contrary to the packaging, it does not dim. If you try to turn it down, it flickers like crazy and flashes on/off. Garbage. Do not buy. It's just a waste of money.

Q & A
How long is the neck of this bulb. Can I use this bulb in my ceiling fixture? How do the lumens compare to the traditional 75 watt bulb this would replace in my ceiling fixture?

The neck of the bulb is approximately 3 1/2" in length. This is made to replace a PAR38 halogen bulb and should fit into most fixtures that currently have a PAR38 bulb. The lumens for this bulb are less than most 75W PAR lamps however; the manufacturer has tested the product and they have determined the light output is equivalent to a 75-watt incandescent bulb.

Product Support

This has less lumens than a 75 watt halogen. I'm not sure about how it would compare to an incandescent. (halogens are more efficient than incandescents). As far as the length, I'm not sure exactly. But these are way wider than a 75 watt halogen. They wouldn't fit in my fixture
