Two spot lights w/ disco ball.

We love it. Looks fabulous in our 40x60' dance floor. The motor and both lights need to be mounted on the ceiling and need a power outlet. Go with two lights over one. one is ok, but spot lights made it really pop.

At our local dog park we call these disco lights since so many dogs have them and when they all run around it is a great light show. They do come in different colors. The way they are packaged in the store though the color isn't listed so you get what you get. Visibility is good, but mine says visible at a half mile. That seems like a stretch. Also if you put it on the dogs collar and it dangles down you will only see it when the dog is headed toward you. But all that aside they are fun to have and makes your pet easy to spot when out playing.

These should be fun at the party. Do be aware that the temples have rather large boxes at the end of each one. One houses the battery and control switch. I assume the other is for balance.

Bright WHITE LED lights are in the center of the disk and shine out in two opposite directions. I ordered this knowing there was only one disc in the package but I think the photo could mislead some into thinking there are 4 in the package.  I thought/expected that the rim was going to glow or light up in a bright neon color but its just the white LED light that is thrown across the inner surface of the disc. Biggest issue for me was that I bought it with the intent of throwing a glowing disc for fetch with my dog after dark.  Unfortunately the LEDs throw a spot of light on the  ground that he gets distracted by and wants to chase, which is another game we play with a flashlight.

Yes this is easily the best disco light sold online. Don't waste your time looking at others if you really are looking for a fun party.
Super bright colorful patterns and high quality effects fun though soothing to the eyes
Super stuff.

This is a great deal, even when compared to traditional spot or street lights.

 I give it 4 stars instead of 5, for two reasons:

 1. It would be great if the motion sensor could be adjusted on another axis.  I you hang it up high, then you can only point it straight down in front of the light to get full coverage, if you point it to the side, then half your coverage is wasted in the sky.

2. The pigtail is rather short.  A few more inches would go a long way.

The lights are very compact and bright. You can connect the two lights together. I just want to point out that the connector is only 6.5 inches long, so the lights will be relatively close together. I would say this is the only small issue with these lights. However, you can use just the one light if you only need one. There is one power cord included. I believe you could buy another one if you want to keep the lights separate.

There are also two types of clips supplied, which will allow you to install the lights at different angles. Very versatile. Once you screw in the clips, the light easily snaps into the two clips.

These are the best LED strip lights I've seen at this price point, even if you were to only use one. They turn on instantly. I actually went to Home Depot first, but didn't find anything comparable. I used these to replace some old fluorescent lights which would flicker and hum all of the time.

This is a lovely little glowing ball of light. I may pick up some more for my backyard. I have it in a spot that needs a little nighttime illumination but that doesn't get direct sunlight during the day. So the nighttime output is pretty dim. When the light arrived, it was fully charged and quite bright. If you put it in direct sunlight during the day, no doubt it would give you a brighter nighttime output. Pretty and inexpensive - a good choice.

$60 at Spencers and half the price on here. This light is pretty awesome. Perfect for trippin balls. Thank you! :')

I purchased the two blue and orange LED lights for use in creating my friend's Portal-themed birthday cake.

The two lights used were:

I have uploaded the final images into the Customer Images, so hopefully you can see how well these lights performed (as well as the awesome Companion Cube cake created by my friend).

For those looking for a non-Portal specific light review, I can say that these lights were very bright, and stood up to a lot of abuse - both while wrapping and rewrapping for the actual cake presentation as well as afterwards, just being thrown around the house (trying to figure out another use for them). After being thrown around and roughly stored for a few months, plug them in and they work just like new.

Very, very dim for 10W.  Beam is too narrow for stage use, only for lighting small objects on walls, maybe.  Spot hits a disco ball nicely, but isn't powerful enough to create much of an effect if the space has any other wash lights.

This one light will illuminate a football field. I also bought a second smaller on to stack.

It's okay but I expected a little more.  My last one just died but for the price, I couldn't beat it, so I got another.  A spindle inside rotates the dome which throws RGB LED lights around a small space.  It's perfect for my small studio when I'm on the air, DJing.  Since people can log on and watch, I have a disco ball and the lights look nice.

This one works better than the last, so perhaps I got a dud.  The first one I got is still going, so two out of three isn't bad...

I did my research prior to purchasing any lighting for the interior of my vehicle. Many options and settings to choose from. What caught my eye was the option to hardwire and have it be part of the map lights or dome light for when the doors open as passengers get seated. I did a full L.E
D. conversion and it looks great. Also cool if you want disco lights to react to bass or some mood lighting. All in all relatively cheap, easy install, and good for extra lighting. I'd def. Refer this product to a friend.

Excellent price tag for this one ( $15 ). So far this does exactly what I would like it to do. Lights up a dark room very good. I also enjoy how you can shift the speed around to match very close to some great dance beat music. Very glad I got this and will probably get a few more, why not, only $15?!

I must give this a strong recommendation! Small unit but with an unbeatable price. Only negative opinion I can give is it has a pretty short power cord. Once you see this in action you might consider what I am, getting a couple more :)

This is a fun product and works well.  Sometimes it takes turning the lights down to make it work better.

Nice supplement lighting for Black light party.
