These are an excellent product at an excellent price. I got floor lights for flexibility - even though they'll be used on stands most of the time or sometimes on wall rail.
The dip switch system is easy enough to use. I don't go in for flashing lights or music controlled lights but those functions are there.
They can be used individually with the dip switches, but I've also got a small controller (Stairville DDC 6 DMX) which has basic control, and some dmx leads to connect the lights so I have more control during a gig. All I need is to be able to change the RGB balance and raise and dim the light which is easily done through the controller. Without the controller you can't raise and dim the lights, but you can have basic control over the RGB through the dip switches.
I've used some of these lights for the last year or so and have never had a problem with them. They are sturdy enough for the price, and it is a very good price.
I use the lights in small spaces - gigs in a gallery and in an old chapel - so I don't need a huge amount of power - these give me enough to add atmosphere and to highlight the performers.
There are two versions of this light - one for hanging off a stand, and this one which is a floor light, but although it's called a floor light it will also obviously hang off a stand - so it seems mad to go for the other one when you get that added versatility for the same price!
