PeteCress 0 Posted September 6, 2013 I got one of these http://tinyurl.com/l6tngvq back in November 2012. Quality, of course, isn't much.... One might even use the word "Junk".... but it does what I want done and I am going to buy a few more - although this particular one is no longer available. There seems tb two strategies for executing something like this: a few more powerful LEDs as in the one I have or many less-powerful LEDs as in http://tinyurl.com/m5dpnbl. Are there tradeoffs worth considering between the two approaches? Fault tolerance? Obviousness to passers-by? Other considerations? Share this post Link to post Share on other sites
