LED lighting panels

[cropwell]

I would just like to add my little bit :- If you buy from ebay, most sellers are acting as second source. i.e you don't have the redress of warranty in the case of premature failure of goods. Some sellers may do the honourable thing, but they have no compunction in law. Amazon offers better protection, but the prices are higher. For things like lighting panels, I would stick to a reliable source like CPC or RS.

...probably not a lot...

Also, some times management's decision can not be overruled by an engineer's recommendation. Especially not in those cheap labour countries. So maybe it's not the designer's fault but the management taking stupid decisions without enough knowledge about the subject.

Putt's Law comes to mind here...

"Technology is dominated by two types of people: those who understand what they do not manage and those who manage what they do not understand."
