Perhaps you have not seen TV abroad. e.g. view New Zealand TV and you come to appreciate the BBC.

Apple agrees to pay £136m in back idiot taxes to UK taxman

VAT payment

For all physical products sold the UK, the taxman actually gets 20/120ths i.e. 16.7% of the price as VAT. So it is indeed more than your 10%,

New MH370 analysis again suggests plane came down outside search area

Re: Now this is intersting

I understand that many low-earth orbit satellites (around 700km above the earth) designed for ground mapping switch off many of their systems when over the sea to conserve power and also reduce sensitivity to radiation. In addition to this, a plane moving at 700km/hr with a satellite passing by at 30,000km/hr would be unlikely to be recorded by the satellite designed to map the ground.

Criminals make money by whatever means possible.

If drugs were to be legalised such that the livelihoods of the drugs criminals evaporated they are unlikely to get a job shelf-filling in the local store but would find other "easy" ways to make money. That could be by a programme of kidnapping (it could be you or your's abducted).

India orders 770 million LED light bulbs, prices drop 83 per cent

Re: Hope they keep a close eye on the quality and design...

It is difficult to diagnose a situation from afar but I think that the current rating of the PSU is unlikely to be a direct problem. What is likely to have happened is that the PSU has been designed to a price (i.e. cheaply) and provides the specified output voltage at a particular current. The regulation of the output voltage may be poor and so, with the reduced load of the LED bulbs, will output a higher voltage than the LEDs can comfortably handle. The LEDs would have taken too much current, been very bright then overheated and eventually failed.

So the problem may well be that there is a mismatch between the PSU and the LED needs.
