Pros: I have this in a small table lamp on my bookshelf; it is pointed towards a wall, and when turned on projects a wonderfully soothing glow. Transitions between many colors.
Fits in any standard U.S. socket, and so far is still working perfectly (after 1+ months of use)

Cons: Transition to red is very abrupt, sometimes it can be distracting.
When I received my bulb, a small chunk had been broken off the outer rim during shipping. It does not affect performance of the light, but there is a small chunk of glass trapped inside the bulb that rattles when I pick up the bulb.

Other Thoughts: Cons are not really cons; it's a wonderful buy and I guarantee you will not regret purchasing this. Costs 10 times less than a comparable mood lamp, and works 10 times better.

Bottomline: Buy it.

Pros: Sturdy.
Not much colour aberration at the edges of the circle of light.

Cons: Dim.
Small flood circle.
The LED assembly was wobbly inside the reflector layer.

Other Thoughts: Once turned on, appears to starts the cycle at a random colour.
Short, hard to screw into some recessed sockets.
Box reads:
"
Low power consum-
ption. Long life. Cold ray
seven color(Red, Blue,
Yellow, Green, White
Purple)
High brightness, High
reliability.
With a controller, it is
color changeable and
flash
"

Bottomline: I put one in a diffusing lampshade on the third floor staircase landing (it casts wonderful shadows through several floors of banisters), and one in a porch light to gently colour the branches of a birch tree outside my window.

Pros: Small, look good, price is very good when We compare it to similar products in all retail stores around here. like always...

Cons: DIM LIGHT.
No instructions/manual/specification sheet were included with the box, but I am not sure You realy need them...

Other Thoughts:

Bottomline: Realy cool, as always.... realy Cheap compared to retail stores around here
and very nice. we will buy more and gave them to our geeky friends.
Thank You dealextreme.
GOD bless You. From The moment I have found dealextreme, I made my homepage.

Pros: It slowly fades the Red, Green, and Blue leds to create an ever changing spectrum of color. Looks great when used a short distance away from whatever needs to be lighted.
Very sturdy construction, easy to put into any regular 110V AC socket.

Cons: The light output is not too great, and all four of mine have somewhat uneven lighting amongst the LEDS (the blues are all the same brightness, but some of the reds and greens seem slightly dimmer than the rest).
As a whole, though, it is hardly noticeable.
Also, the color yellow is never produced. The pattern of fading LEDS is such that Red and Green are never the only ones on.
So basically, the colors this produces are:
Red
Magenta
Blue
Cyan
Green
and White (which is more of a blue-ish white)

Other Thoughts: This LED light looks great when used as a short distance spotlight, I'd say under five feet away from the object to be illuminated. (which is what I used it for).
Don't expect it to light up a room though. I had four of these turned on every night, all night for about a month, and none have failed.

Bottomline: Compared to similarly featured color changing LED lights on other sites, the price just can't be beat on DX! They look good, and are worth buying if you want to add some color to any part of your home.
