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).

I would buy this product again. Love having around


Our house has standard lighting all throughout. We bought these bulbs before for our indoor lighting and then needed them for outdoor too. We love having the bulb finder as a tool.

13 W. 4 pin


1st order of 3 had 1 that didn't work. Replacement arrived within 1 week. Doesn't get any better. Local stores do not stock any longer.

Good lights!


I think these lights are good. The delivery time was great. Pendants we put up in a new house had one that the light was broken. I had a hard time trying to find these in any local stores so I had to order them on line. Can you tell me if there are conversion parts so these lights can become screw based and not 4 plugs? I cannot get a dimmer on the pendants but if we can convert them we can. Also, it will be much easier to buy replacements if the bottoms are screw and not plug in. Thank you!

Halco 13W 4 Pin GX24q1 Warm White Spiral CFL Bulb

Q & A
do these work off 277v, 120v or do they work off of existing ballast


Hello, CFL's are self ballasted bulbs so a ballast would not be required when using it.


the base of the bulb I am trying to replace is stated as GX24Q. The base on this bulb is stated as GX24Q-1. Are these the same? Does the "-1" still permit this bulb to serve as the replacement I need?


To best figure out if the base is the same, take a look at our compact fluorescent bases reference chart and match the base on there to the one you have. Here is the link


I'm looking for a PLS13.50 bulb. Is this bulb compatible.


While most of the specs appear to match what you've provided, this product code seems to be for a low profile plug-in. If the length of the bulb is a factor, this may not work with your fixture. Please contact Customer Service at 888-455-2800 for further assistance.


Is this bulb equivalent to FEIT Electric PLSP 13E, 13W, 2700K, with G24q-1 base?


Yes, this bulb has the same wattage, color temperature and base as the one described.


The bulb I have has on the side TCP33014M 14W2700K and is in a Hampton Bay Fan Light Is this a replacemement for the bulb as the picture of the bulb looks exactly the same as the one I have Mine is 14W but the specs of the replacement bulb is 13W


This bulb has the same base as the 14-watt TCP product. The ballast that the bulb plugs into will be able to handle the 1-watt difference.
