 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.

Great lights

I put these lights on my porch. They are so bright I did not use all the strings I purchased. The color is close enough to incandescent that it does not look ‘LED'.

Great Lights

Great Lights and good quick shipping. I got them very fast. Nice to add a little festivity to the holidays.

Exactly what we wanted

These are definitely brighter than the old incandescent lights, but the warm tone is spot on and an excellent replacement. Will definitely be coming back whenever we need more warm LED lights

Just what we want to do our tree in. They are perfect. Just the right elimination. Thanks

I have to admit I prefer incandescent lights, but I wanted to see what these LEDs were like compared to the incandescents I purchased. They have a bit of a yellowish color, so to my eyes they don't appear to be as natural as I'm used to, and they are brighter than the incandescents. But the quality is there, and I can see using them on wreaths, garlands, or outdoor applications. If you need or want to use LEDs, I don't think you'd go wrong with these quality lights.

Wonderful lights!

These are the best fairy light strings I’ve ever had! I bought 11 strings and every one of them was perfect! They give off warm light and are surprisingly bright for such tiny bulbs. The bulbs are sealed against the weather and are working well despite our winter storms. Excellent lights!
