I thought I would try this question here first since someone is always
willing t help with their expert advice... Anyway....
I am looking at buying some LED's t brighten up a small area and have been
stumped by their specifications and their meaning. I understand most of it
but what does viewing angle mean ? I though an LED emitted light all around
but then I found specs at Maplins and these have a viewing angle mentioned
(http://www.maplin.co.uk/products/frameres.tpl?partcode=JA24B:JA25C:&SKU=127
03&cart=943432253&d=f&max=1&Group1=LED%205mm%20blue).
I would like to use a 12v supply but does this mean because they are rated
at 5.5v max that I would need two parallel rows of LED's with a resistor
and
if so how would I wire them so they don't "pop" every week ?
Cheers in advance
pedro
