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
50 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.

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

Soft 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)

Beam Angle (°)

The width of a light beam, expressed in degrees. The beam angle is often part of the ordering code for reflector lamps. For example, a 50PAR30/HIR/NFL25 is a 50-watt PAR30 narrow flood lamp with a beam angle of 25 degrees.
Beam Angle (°)

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)


Indicates whether a bulb can be dimmed in conjunction with a suitable dimmer control.

Works well in my Kitchen


This bulb is for my kitchen track lighting. It's a good value at this price. There is nothing exotic or special about the bulb. I do not burn them very long per day so they last pretty good. However if you have a lot of GU10 bulbs for your track lighting using high wattages and burning for long hours this bulb might be the wrong choice for you. You should be considering the advantages of switching to LED for an application as I described here, but for my limited purposes this bulb is just fine.

Service is great!


Works fine.

So glad I found


Got a used hood vent for the kitchen stove and one light was burnt. Went to local store and purchased a bulb that looked like a perfect match, it was not, would not install. Got online and found the manufacturer website, replacement bulb was available for $32! The vent takes 4 bulbs, really? Started searching, found, Yeah! Paid way less and they fit perfectly. The bulb from gives a light that is "hotter" (for lack of a better word) than the original bulbs. The light from the original bulbs are more diffuse, but I saved like $100 on 4 bulbs, who cares.

Great for a few weeks.


Bought 12 of these last july. In a fixture of five bulbs, that had 2 burned out, I put in two of these. One died after two weeks. Shortly after, the other one died. Over the following 8 months or so, these new bulbs kept burning out. I am now down to the last two. Also during this time, the remaining three bulbs in the other 3 sockets (not from this batch) are still burning bright and never failed. These things are a waste of money.

short life


It seems I'm constantly re-ordering this product. Many burn outs after 2 weeks. If I could afford LED I would switch.

beware of the cheap


Must have gotten a bad batch. I had to replace 6 I had in there for only a week or so..

Burns out quickly


This is a cheap product that will kill your budget. My 20 bulbs lasted 2 months as they burn out very quickly. One bulb lasted 10 seconds - it popped as soon as I replaced it. I replace this with 35watt bulbs (same company, same model) - and it lasts so much better. Buy 35watts, they don't burn out as fast.

These bulbs burn out quickly and thus becomes an expensive source of light.

They don't last


These bulbs do not last. I bought 5 and they are already burining out and we have only had them for 2 weeks. they are used in one of our conference rooms which only get's used 10 hours per week on average.
