 Technical Q/A

How many light strings can I run in series?   UL specifies that light strings can be run up to 210 watts in series end-to-end in a single circuit. Check the specifications of any light string to confirm how many can be safely connected. Exceeding this specification can damage the light sets and/or blow their fuses.

Do LED light strings get hot? No, LED light sets do not heat up. Unlike glass bulbs that heat up a filament to product light, LEDs generate light with semiconductors. 

Do Christmas light strings have fuses? Most plug-and-play LED mini light strings have fuses in the male end plug. C7 and C9 bulbs and cords that are sold separately generally do not. 

How do I calculate how many strings I'll need to wrap my tree? A quick discussion of an easy way to estimate how many light strings needed to wrap a tree trunk.

Truly warm lights

Just what we were looking for. Hard to find warm white lights these days.These truly are nice and WARM. Very good quality. Will be buying more

Great lights for the price

They are great lights for the price. I selected warm white for that traditional look. They are a little dimmer than I thought but I believe they have options for double brightness but still looks great.

Great quality and price

Was very satisfied with the quality of the lights, Excellent price as well


Excellent quality and color. Brightness is great. Only one bulb out in 75 strands. Good value

Love My 15 Strands

My string lights are hanging from our eaves and lining our pathway, waiting for The Grand Lighting on the night after Thanksgiving. The globes are pretty tough, as I was not particularly gentle when I went about hanging the strings on the eaves. The warm glow is pleasing and not at all harsh. I have four strands left and plan to use them next year on our newly planted trees, as they will be more mature by then. The customer service was excellent. The gentleman with whom I spoke was cheerful, knowledgeable, patient, and helpful. I'm sure I'll be relying on Christmas Light Source for any further holiday lighting needs.
