Hi there,
I'm having issues understanding how Blu-tack acts as a light diffuser for LED's. I've applied a ball to the end, which seems to be far too thick as I get no response and also tried a thin layer, from which I get better response by removing it.
How am I supposed to do this and how thick should it be? (or more to the point, is this even possible as it states on the website?)
Cheers,
Mark
PS I'm using 3 IR LED's with a 25 degree half-angle
