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
9.5 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)

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.

High quality R20 at great price


We had searched local stores & the internet for hours trying to find affordable LED blubs for trac light project. We needed 9 & that could be expensive. When we found this product at we had to read the add several times as we thought we might have missread. A 9.5 watt dimmable LED for an affordable price + free shipping? Hard to beleive but true. Easy to install & as advertised: 50 watt incandescent equivalent, low energy useage & warm white. NOTE: The bulbs do hasitate for a split second before coming on but no big deal. They are dimmable down to about 50% brightness but that could be the type of dimmer we use. Highly recommended!

Q & A
Will this bulb work for high hats or does it get too hot?


Providing the bulb is not fully enclosed within the fixture, there shouldn't be a problem.
