I use from time to time purchased this light there is more than a year.
This is a surround effect that projects four different colors following: blue, pink, green and yellow in the form of liquid surface aspect (same effect as watching a lorqu'on pool)
Lamp: ELC 24 V 250 W
the + Effect original and thus appreciated in general. nice surround effect if the project on a white wall for example. Can also be directed to the dance floor. Ability to block the same color with a remote control. I like the pink color that can give a warmer ambience to rooms austere.
the -: although it is a bulb of 250 W, low light. That's why I recommend putting it in front of a white wall or ceiling
In short, it's a nice little effect, a little more for small parties.
