I'm looking for help with lighting a model. I have a panel about 1.5" long which needs to be backlit with red LEDs. The problem is that even one 2032 battery in its holder is pushing it for space, so I am having trouble getting the backlit panel to light up evenly with such little power. I first thought one LED would do the job, but the panel is dark at both ends. It looks like I need at least two LEDs and they will need to be as bright as possible.
Can anyone tell me what sort of red LEDs and what resistors will work best and be quite bright using just one 3v 2032 battery to power them.
Can I run two LEDs one 2032 or is there anything more powerful than a 2032 which will take up the same or less space?
Thanks,
Keith.
