Product Highlights

  • Energy efficient replacement for a conventional 50/100/150 watt bulb
  • Estimated life of 9.1 years based on 3 hours use per day
  • Clearance

Litetronics brand "three-way" compact fluorescent lamp.  Selects between 12, 22, and 33 Watts of power, producing equivalent light to 50, 100, and 150 Watt incandescent lamps.  Warm white color and high color rendering mean you'll never know the difference, at least until you get your electric bill.

  • Outstanding energy efficiency - provides equivalent light to most incandescent lamps while using only a fraction of the electricity

  • Outstanding life - 10,000 hour rated life is five to ten times as long as most incandescent lamps

  • Outstanding value - replace your existing lamps with more energy efficient technology, at a competitive price

Three-contact screw base, suitable for use in "three-way" fixtures.

NOT RECOMMENDED for use in enclosed fixtures or for use with control devices such as sensors or dimmers, may shorten lamp life

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".

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'.

Customer Reviews

Thought it would be brighter


I purchased this bulb because I couldn't find anything else to work with my lamp that takes 50/100/150 watt bulbs. I was disappointed in that it doesn't get bright and fill the room with a lot of light like a regular bulb and my other spiral CFL bulbs do. It's okay if you're not expecting a lot of light. I do like that it is shorter than most so it doesn't show over the top of the lamp bowl.

Good light for reading


Replacing a "standard" 3-way in thesmall lamps in the living room. This bulb gives good light and good color to the area, and lasts 1-1/2 to 2 years in the way we use it.

Thank God for "Litetronics"


Thank Goodness for a company like "litetronics" who is the only company to ever make a 3 way 50/100/150 cfl replacement light bulb that fits into a standard table lamp without using anything i have been searching for years to find a 3 way bulb that fits & finally found it @ If anyone is looking for 3 way cfl replacement bulbs. Litetronics is the place to go.




Affordable 3 way bulbs


Was glad to find 3 way bulbs in the brightness/color we desired.

Low Profile 3-way CFLs


I purchased a new table lamp in which I intended to use a CFL bulb. A standard CFL bulb did not fit. This low profile bulb fit perfectly.

okay bulb


[...] the new bulbs just aren't as good as the incandescent and tend to burn down in the amount of light given out fairly quickly. it's the same with all the eco friendly bulbs. they give out a lot of light for a short time and then start waning.


new york, ny




Using it in a torchiere lamp w/3-way socket. Bought a bulb a "big box" store but it was too tall and could be seen. Saw the shorter version and tried it. Fits well and can't bee seen. Only wish it was available in say 35/50/75 instead of the 50/100/150.




A "real" compact 3-way fluorescent


It is REALLY nice to have a 3-Way CFL without the "harp extensions". My old 3-way CFL was way too large for my old harp and lampshade. This one is just the right size for my reading lamp.

I would buy this product again.


This CFL 3-Way Spiral w/ Med Base fits well in older table lamps designed for incandescent bulbs.

Q & A
I would like to no where this light bulb was made. It does not have it on the bulb. thank you


This Litetronics bulb is manufactured in China.


This bulb is advertised as LOW PROFILE, but the Product Details show the overall length as 5.375 inches! This is longer than a normal CFL bulb, so the specs must be wrong. Please verify the true length.


The true length is 5.375". It is reasonably short when compared to CFL lamps that provide light output equivalent to 150 watts. Additionally, this length is the same/similar to the legth of an incandescent 3-way bulb.
