LED PST-9W TCL DMX Spot : Not that useful for mirror balls

Pros:

Includes short DMX cable for daisy-chaining

Really a projector, with very sharp beam edge

Great for mass installation in fixed locations

Cons:

Need to buy one/two DMX adapters per daisy-chain

Not very robust, not recommended for gigs

Very limited use with mirror balls

Review:

These are great value for money if you need a small fixed spotlight with changeable color. Its low price and power consumption makes it useful for mass application, e.g. in curtains. Its light output is quite impressive for the size and price.

Note, however, that the three colors (RGB) are emitted from different parts of the lens, due to a simplistic optical design. This means that if you light up a mirror ball with white light, you won't get white reflection spots but for each mirror there will be three separately colored spots. Therefore, this armature is only useful for lighting mirror balls in pure red, green or blue color!

And when illuminating for instance a wall with white light, expect color fringes on the otherwise quite sharp spot. This can be remedied by opening the enclosure and shimming the main lens, but this mod is definitely not for everyone (and probably voids the warranty). A pity they couldn't afford focus screws.
