About Christmas lights
August 6th, 2010C6, C7, C9, M5 —- agh!!
What is the deal with all of these different sizes of lights, what’s the best for what? What can be used outside or inside? These are great questions and I’ll try to answer them here.
Classic Lights
C6 – Intended of outdoor use, the C6 is a great choice for hedges, bushes, or smaller trees outside. The C6 has the smallest bulb of the C series, but due to its smaller size every bulb only uses 4 watts of electricity. LED versions of the C6 are also available.

C7 – Used for moderately sized decorating projects, the C7 is ideal for putting on the house or for lighting up some of the larger trees in the yard. Each bulb of the C7 works on 5 to 7 watts. LED versions are readily available.
The standard incandescent C7
C9 – As the largest of the C series, the C9 is used of the larger scale decorating. Most often the C9 is the primary mainstay for commercial decorating due to the C9’s ability to emit more light . The C9 uses 7-10 watts per bulb and LED versions available.
Mini Lights
M5 – Of the mini lights, the M5 is the most frequently used for both indoor and outdoor decorating. At 1 to 1½ inches the M5 is the perfect light choice for lighting almost any anything. M5s use 2.5 to 3.5 volt bulbs which are more energy-efficient than the classic lights.
The incandescent M5
M6 – As the bigger brother of the M5, the M6 is about an inch or so longer and just a little wider. Because the M6 is larger it is many times used in commercial decorating. M6s are also use in residential decorating projects but not as regularly. M6 draw about 3.5 to 4.5 volts, but the LED versions are much more efficient.
The LED M6
G12 – The G12 is a hybrid between the mini and classic lights. The G12 isn’t long and slender like the M series or elongated like the C series but rather round. However, the G12 is classified as a mini light because the bulb is one-half inch in size. The G12 is used for indoor and outdoor use, and it can be put on things such as Christmas trees, shrubbery and roof tops.
The more commonly available LED G12
G25 – At the bulb size of 0ne inch, the G25 is the largest of the G series and ideal for medium decorating. The G25 offers some more light due to the larger bulb size, and it is also great for trees and shrubbery, but also nice to use as a way to dress up a patio or walkway. The incandescent versions are available but the LED is much more energy-efficient.

Novelty Lights
Shaped lights – Of the novelty lights, shaped light are the most common. These lights can be in the form of snowflakes, stars, ornaments, or even chili peppers. Shaped lights can be used both inside and outside, in such as snowflakes on a Christmas tree or stars above a manger scene. There are also many LED types of shaped lights available.

Star Lights
Bubble Lights – Like mini lava lamps, bubble lights are filled with colored liquid which when it becomes hot it causes bubbles to come up from the base of the light. Bubble lights come in a variety of sizes and heights ranging for 3 to 6 inches. Bubble lights are normally for indoor use and they can be put on Christmas trees, mantels, and other room décor.
