I have had problems with all of the 3 types of Stairville LED par cans that I have in my rig. At first, it was a suspect batch of LED PCB's on the par 56's, which had multiple LED failures. Thomann sent replacements for the 4 that I had purchased together, instead of shipping them back for repair. Only 1 was faulty at the time, but I have since had to replace 2 other's, leaving me with 1 spare left.
Then 2 of the PAR 64, 36x1W LED par's stopped working all together. These were shipped back and repaired under Thomann's 3 year warranty.
I now have a problem with 4 green LED's failing on 1 of the short par64's with 183x10mm LED's. It is still otherwise fully functional, but looks a bit naff. Thomann are arranging for shipping and repair, instead of sending a replacement PCB, so this may not be a common problem.
I purchased my LCD rig to be ECO minded and save energy, but shipping stuff to and from Germany for repair, is negating my efforts. It is not costing me anything, except for the short term inconvenience of not having the units available for use.
Maybe I need to up-grade to a more expensive, but more reliable brand. Anyone else having problems with Stairville products? John.

I rigged all of my 18x LED par's at The Chinnor Bike Dayz 14 on Friday 2nd, July and added 4x of Andy's. During the first evening of live music, 2x more multiple LED faults appeared. A row of 4x LED's on a par 56 were flickering and another row of 4 on another unit just failed.
This was not a problem for the gig, as there was plenty of output and I had to dim them when the daylight had completely gone.
However, on Saturday I noticed that all of the faults had gone, including the original one. All 22x par's were fully functional.
I can only assume that the searing heat of the sun had either dried-out some dampness or cooked the gremlins.
The stage lighting looked really great and the new desk worked very well.
So there you go, if you have problems with your Stairville par cans, take them on Holiday. Cheers, John.

I have recently purchased 4x Stairville Diffusion Filters for my new LED Par 56's, that I have rigged to my studio ceiling. As these are fairly close range, the filters prevent the "retina rash" effect and diffuse the light into a solid colour. www.thomann.de/gb/stairville_diffusion_filter_fuer_led_par.htm John.

I used my Stairville Diffusion Filters on 4x LED Par 56's, at close range, low down pointing up, from the FOH speaker poles at a charity gig at the Breakspears Arms in Ruislip on Saturday. None of the band's complained of being blinded/dazzled in any way.
With 4x more LED Par 56's ( without filters) and 2x LED Multi-spots on 2x trees either side of the drummer, the fairly small stage was well lit.
Coupled with an awesome sound from the 4.6kw rig out front (my 2.4kw rig + 2x of my JBL MRX512's and the venues 2x 800w subs) and only 2x monitors, the event was greatly received and raised £600 for the late Paul Fox's (RUTS) charity, The Micheal Sobel Cancer Trust.
Cheers , John.
