When purchasing LED Christmas lights, bulb size is an important factor to
consider. Bulbs are categorized by letter and number to help you select the
ideal size and shape.
C stands for cone and the number corresponds to how many eighths of an inch
in diameter it is at the bulge. G stands for globe, because it is spherical in
shape.
An advantage of G bulbs is that they look similar, no matter what angle they
are viewed from. We also have mini lights that come in two shapes: the torpedo
and the conical. The minis and globes have diameters measured in mm, so a 5mm
mini torpedo is 5 mm in diameter, which is 1/5 of an inch, similar to
traditional mini incandescent bulbs.
We tend to think of Christmas bulbs as "large or small and for typical
LED one-piece strings, where the bulb is permanently fixed to the string, the
large bulbs are spaced more widely than the small ones.
The large bulb group is comprised of C7, C9 and G25 bulbs and is perfectly
suited for outside use since the bulbs are larger and the spacing is greater,
so you can cover a larger space on a budget.
On the premium strings, spacing is usually 8 inches while spacing on the
commercial strings is usually 12 inches. The small bulb group is comprised of
the mini conical, C5, C6, G12, and mini torpedo shapes and is great for indoor
or outdoor use.
The spacing between the bulbs is usually 4 or 6 inches. The mini conical
bulb shape is our most popular. The bulb has a lens that radiates light in all directions,
creating excellent dispersion.
