The Brightest and Most Durable Christmas Lights

Conical 5mm Wide-Angle LEDs are the most durable and brightest Christmas lights available.

Almost every professional Christmas light installer uses conical LEDs for their displays. Conical LEDs are waterproof and snowproof because the LED is injected molded into the plastic cordage. Conical LEDs are also 25% brighter than an incandescent indoor Christmas light. The brightness comes from the intensity of the LEDs and the magnification of the conical lens.

Overall, LED lights are a great choice for Christmas because the lights 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.

  1. I can’t seem to find the small led string lights that are domed which when they are lit, some bulbs appear brighter than others due to looking either straight at the bulb or from the side.
    Can anyone help?

  2. I need the brightest Christmas light I can buy. I would prefer Led lights. We live .5 miles off the road. We put up Christmas lights and you can’t even see them from the road. If anybody knows about light could help before I order I would really appreciate it. Thanks Jeff

  3. 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.
