I am looking to try something crazy. An LED flash bulb for a camera. I have 5 volts to work with and I am looking to make a PCB with an LED or several LED's. A few questions for anyone with experience.
1 - Does adding an additional LED increase the brightness?
2 - Can I 'over drive' an LED since I am only nailing it with power for 1/4 second or so.
If anyone has some tips on trying to get a high intensity light output from an LED, or several with 5 volts @ 1A current supply it would be appreciated.
