Overall, LED lights are a great choice for Christmas lights because LEDs almost never fail, and they are impervious to freezing temperatures. They are also much more energy efficient than incandescent bulbs. For this reason you can string up to 40 sets of LEDs together, and plug them into a normal electrical socket.

Conical LEDs are not recommended for indoor use due to their intensity (M5 or C6 LEDs are a better choice inside).


Conical 5mm LEDs are available from Amazon and eBay.

  1. Hi Jackie, internet rando here. The article says the conical LEDs are too bright to be comfortable for indoor use. If you want ’em really bright, why not try it? Or, the article says go for M5 or C6 LEDs which I guess aren’t as bright. I’m going to guess that code refers to the bulb type, so you can buy from different manufacturers on different years and get the same visual effect for your whole collection.
