Just a heads up that I have recently discovered sellers on eBay that have stole my images and used them to try and sell cheap strips of LED, I want to assure everyone this is not as good a quality as what I use and apart from here on TRO if the kit is not sold by RickHondaR then I assure you its not a genuine product and the quality and instructions will not be as good.
What I will say is to start with all the LED and specs were about the same when it was first developed and it was very very expensive (around £40pm) but then as always competition set in and the product become cheaper as it was mass produced, what also happened then is some manufacturers looked at other ways to make this even cheaper and this is were they cut corners for example
1. Swapped copper conductor in the PCB to aluminium then this was taken a step further to basically tin foil you wrap your sandwiches up with, well to be honest some tin foil you have at home will be better quality. I have sample tapes were the copper or alloy PCB is thinner than the 3m sticky tape backing you peel of to throw in the binThis effect the durability plus the quality of the product.
2. Originally it was all a double sided PCB tape but again now the cheap stuff is only single sided and to be fair very thin is metals cost money but this also makes the tape weak and tear easy.
3. Quality of the LED chips and resistors, I have been informed a lot of the cheap low quality stuff is made from the LED chips that fail quality control so in fact the light output of each LED chip will be lower or life expectancy will be lower. Now this could be only 10% difference or 50% difference but at the end of the day still a second, A good example of this is a bit like Intel used to re-badge and lock down under performing Pentium P4 CPU and cell them a Celeron back in the day.
Well I did not move with the times I stuck to the original spec and high quality product that was first manufactured and yes this costs more but then its also reliable and effective a good example of this is how I fitted around 40m of my LED in a local restaurant 5 years ago and this is illuminated for around 8 hours a day 7 days a week and not a single issue in all that time.
You get what you pay for full stop!
I will say as well that I might be upgrading to the very latest LED chip in the next 6 months or so (have stock to move first ad the new chip has only been on the market around 6 months), this is still mounted on the same high quality copped double sided PCB but the heat sink on the LED chip is around 3 times more efficient which has also made the LED light output around 130% brighter and for my non car sales this is now all I am using. I am currently thinking is this better for a car or to bright and better sticking with a tried and tested product plus I can not at this moment in time have the chip on a black backed PCB were I can in the old spec.
