Energy Used

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

Incandescent/Halogen Equivalent

The wattage value of an incandescent or halogen lamp of similar brightness.
Incandescent/Halogen Equivalent
35 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
Bulb Color
Soft White

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'.

Great replacement for halogen


Lights the Kitchen up just as good as halogen, just takes a few minutes for the florescent to get to full strength




much better than halogens


These are replacements for halogen bulbs. I couldn't stand the heat from the other bulbs. These are a lot cooler. The only downside is that they take about 2 minutes to get to full brightness.




Bigger than normal and need to warm up


These bulbs are a bit longer than the bulbs they are replacing in a track-lighting system. They protrude from the holder but my fixture is modern looking so it doesn't actually look bad. The only downside to these bulbs is that they need to warm up. When I first turn them on, they're at about 15% brightness. It'll take a good 30-60 seconds before these fully shine. Once they do, they're great. The color is very warm and the spread is great. My wife didn't even notice the difference from the incandescence they replaced, and run A LOT cooler with less wattage which is awesome. Normally I'd give these 3 stars but since a low-wattage GU10 base bulb are SO hard to find, and LED versions cost $50-$100 each, these are an excellent replacement for relatively small price difference.

Q & A
What is the beam spread of the bulb and why it is not stated as it is stated for LED and halogen bulbs just to get a rough idea.

There is no beam spread listed by the manufacturer. The reflector contains a spiral compact fluorescent and it is very difficult to control or direct the light output. Most compact fluorescent reflectors are considered floods and can range anywhere from 50 to 60 degrees (or wider) depending on the size of the reflector and/or the type of fixture it is used in.

I would like to know the difference between the product 1 and product 2 as below, particularly in its dimensions, Product - 1: 35W Incandescent Equivalent 11 Watt, JDR CFL Lamp with GU10 Base; SKU: 11W/ODJDR | Ordering Code: 11W/ODJDR (GU10 Base) Product - 2: 35W Incandescent Equivalent 11 Watt, JDR CFL Lamp with GU10 Base; SKU: 16174 | Ordering Code: 11W/CFL/GU10/120V (GU10 Base)


The bulbs are similar in many aspects, such as dimensions and average rated life. They are different brands. One is Overdrive. The other we list as Value Brand, since we do not have any history with the manufacturer. The packaging on the Value Brand product listed the light output much higher than the Overdrive however; we did a side-by-side comparison and the light output was similar.
