Stairville LED PAR 56 black 151 LEDs RGB

Bought 2 of an early version of these back in 2008 and have been using them ever since with no issues.
They seem to have dropped in price since back then and that possibly reflects that they do not shine as brightly as conventional lamps but are much less fragile and much less hot if you have to stand under them!
With the casing of all metal construction, they have been very reliable and none of the LEDS have failed ..yet! Have 2 on a lighting stand at one side of the stage and their sound activated sensor just changes the patterns in time with the music. You can of course connect them to an external controller too.
So at their current price they are good value but don't expect a really bright light!

This parcan is the most basic of the range of LED Parcans, but that doesn't mean it won't do the job. I have 4 of these currently and they are all extemely lightweight, robust and effective for simple colour effects, a close up wash on a wall, or as part of an event/disco setup. The affordable price means the more you have, the more effects you can create. One small draw back is the 8 dip switches meaning a total channel combination of 255 rather than a useable range on this unit of up to 510, so in larger rigs they may have to be sensitive to the address chain. They respond really well, the electronic dimmer is smooth and the colours are punchy and effective for a small venue. The colour blending is not even as the LED's are exposed, but for colour effects as part of a disco/event, they are perfect. They also come with a grilled colour frame for adding Frost if needed.

There are a pluses and minuses about these PAR.
Firstly about minuses:
The main problem is quality, you can't transport these without special hard cases, because it is fragile and you can easy to turn down side parts. So you need to be very careful about that.
Other thing is light output, you can use this only on small stages or use as accenting decorations.

Pluses:
It is very light and easy to carry, it is a good choice when you have limited space for transporting, for example, a car.
In the other hand, it have many good features in this price range like DMX channels.

In conclusion, if you have a band or a small club, this is the right choice.

I've been using a set of these in a very non-professional way on maybe 30 small gigs now. They do not have much light output as such, but are good for coloring the back wall or player's profiles or whatnot.

The built-in automatic program works fairly well giving smooth transitions between all the colors. Only when it cycles back to the start of the program there's an irritating abrupt change. The "music-controlled" mode is almost useless because there's no threshold setting and it is way too sensitive to use with live music.

Couple of my cans have taken some damage and have some dead LEDs, but otherwise they've hold up much better than I expected from something this cheap.
