70 5mm LED Lights, Blue

I have seen blue lights before at Christmas and they are so incredibly dim which I could never figure out why. I never bought any but recently I went in to Lowe's and tried a string and even though they were beautiful they still had that freakishly dim look. I have purchased lights from this site before and when I saw the blue LED lights I bought a single 70 count string. When they arrived (practically overnight?), I unwrapped them, laid them on the floor in a straight line, plugged them in, and WOW, bright doesn't even begin to describe them. THIS is how blue lights should look. Fantastic!!!!!

BLUE lights!

Wow! These lights are the perfect blue color, you know, the kind that are so bright and blue that you almost can't focus on them. Once I got these, the quality of the lights and wire is readily apparent. These are so much better than the crud you get at all those unnamed retail stores. I highly recommend these to anyone looking!

Outstanding Color, 5mm Blue and Gold LED

Having three children who all attended or are attending West Virginia University, and whose colors are blue and gold, I purchased these lights and combined the strings for our backyard decoration. The color is sensational and really lights up the yard with Mountaineer Pride!!! Extremely satisfied and I WILL be back for more come the holiday season.

Little Blue Lights do a great job. These are not the ones I had in mind when I ordered but I have so many and wasn't sure how to describe them but these worked perfectly where I put them. I have never been unhappy with any lights I have bought from this company. Hope to order more closer to Christmas. I have their lights everywhere and most of the indoor ones are up year round and last forever.

70 5mm Blue LED Christmas Lights, 4" Spacing

I ordered the 70 count 5mm Blue LED Christmas Lights with 4" Spacing at the end of the Christmas season to supplement my current light display for next year. I tested the lights when they arrived, and they are extremely bright with a great deep, rich blue color and the construction quality seems to be very good. The concave lens design creates a very bright light from any angle with the wide angle reflection. Order was delivered quickly and in good shape. I look forward to adding these to my display for next year.

Used this product to create the illusion of ice on a pond. I placed them close to the ground about 3 inches over the ground in a pond shaped pattern and placed mechanical deer on the perimeter appearing to drink from the water or frozen pond. It was easy to install and looks great.

We enjoy using these lights, extremely bright and blue. The ONLY downside is if a bulb goes out you cannot replace it, so you end up with an expensive defective light set. Please fix this issues ASAP, I had five sets go bad in one year, usually only 1 or 2 bulbs quit working. We should be able to replace bulbs.
