What are the differences between C7 and C9 Outdoor Christmas Lights?
The main differences between C7 and C9 Christmas lights are the bulb or lamp size, base size, and the wattage. C7 bulbs are smaller than C9 bulbs with C7 bulbs just over 2 inches, while C9 bulbs are just over 3 inches long. Our C7 lamps come in .6 watt LED, 2.5 watts and 5 watts while our C9 lamps are 1 watt LED, 3.5 watts and 7 watts. C-9 Lights are useful for decorating buildings, particularly those that are 2 stories or more, as these bulbs appear to shine brighter and seem more visible from a distance.
