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
43 Watts

Fluorescent Equivalent

The total wattage of fluorescent lamps in a fixture that this fixture replaces.
Fluorescent Equivalent


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

Bright 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)

Operating Temperature (°F)

The ambient temperature in which the product can safely operate.
Operating Temperature (°F)
-28 to 113

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 (°)

Bulb Power Type

Defines how a lamp is powered, whether it needs a ballast or not, or can use either
Bulb Power Type
Ballast Bypass

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.

Beyond My Expectations


After a lot of research I decided to buy these tubes over all the others I could find to work with an HO R17D socket. The reviews on a lot of other tubes were less than stellar. All the plastic tubes seem to sag in the middle and need to be held in place with zip ties. Other online bulb companies had terrible reviews with regard to packaging and shipping. The Lunera tubes had very good reviews and had the very best price for them. I ordered 20 tubes to replace the HO T12 R17D florescent lighting in my shop. Everything about the product was better than I expected. The product itself is very high quality, the packaging was very substantial, no damage at all in shipping, and attention to detail by Lunera to the level of orienting all the tubes in the box with the line (hot wire) and neutral ends together. Installation was very simple. Remove the old ballast and never have to replace another one of those or hear it buzzing, connect the line and neutral wires, and put the tubes in place. It took about 30 minutes per fixture taking my time to do things right. The 5000K color is very white and bright making it so much easier to see what I'm doing. The Lunera tubes radiate light in a 330 degree pattern so the lighting is very even. Many other brands are limited to 180 degrees.
