I believe the problem, that crept over from ebuild, is the tone of the language used. For example, using the term "Snake oil" humiliates a person that might have been duped, There were too many opening contributions from Newbies" asking for them "to be treated gently", this indicates the fear people have to ask questions in the first place and they have drawn that conclusion from listening to the manner in which questions are answered. I have felt humiliated by responses in the past and I have thicker skin than most. I hope this warning from NSS is heeded on this new forum. Please no more personalisation against professions or products. It is not what is said it is the way it is said. Jeremy please do not assume that people are making personal attacks against you. You have turned the comments from NSS as personal against you and last night you made it sound like I was making personal comment against you and nothing could be further from the truth, but you expressed it in a tone of conflict; simply not needed. I thoroughly enjoy learning from this forum and share most of the points of view expressed but detest unnecessary conflict and criticism. I experience too much of that in my personal life and use the forum to escape from conflict.

The powerful LED strips need a lot of current and are very bright. Three across a 4m width seems more than adequate for me. I've found the best way to fix them is to paint or prime the surface, then stick on a length of 50mm wide aluminium tape (the stuff used to join insulation sheets), rub the aluminium tape down well and then stick the LED strip down the centre of the line of tape. This makes the LED strip adhere better and also seems to make the strip run a bit cooler, which in turn helps the self-adhesive backing stay fixed. For power supplies, I've used ventilated aluminium cased 12V supplies, wall mounted. The bright 5630 strip needs about 3A per 5m length at 12V, and I opted to use three 5A supplies, like these: http://www.ebay.co.uk/itm/12V-24V-IP67-Waterproof-LED-Transformer-Driver-Power-Supply-CCTV-240V-DC-2A-5A-/291663843407?var=&hash=item43e885104f:m:mp4HSAn6fw0MWK4ZUIErztg I ran lengths of 1.5mm² T&E cable above the ceiling to feed the far end of each strip (I've used the full 5m on each roll) joined to either end of the strip and then with single 1.5mm² T&E feeds running to the power supplies, inside a length of conduit where they come down the wall.
