Sorry Relax, completly missed your question.
The Apollo kit is not in that many shops at the moment, but its being worked on! its a reasonably new kit so still finding its feet in the market place.
It's currently only available via the web-site, amazon, ebay etc on mail order. Delivery is free tho within the UK, and not a huge amount more to go abroad.
the trick with the kit is to use a combination of the various size light bars to best fit your screen. splitters are now available also, which means the kit can use up to 24 light bars.
Im afraid i dont understand what you mean by "px" :)
