Can I run an LED at a high voltage?
My LED has a forward voltage rating (as well as max reverse), and it has a max current rating. My capacitor bank is 330V, so once I calculated the resistance I needed for the 20mA I plan to use, I created a board of resistors that will give the required current and dissipate >10W. My 20mA is 10mA less than my LED's max current rating. Its forward voltage is 2.8V.
Even though I have proper current levels and power dissipation, will the 330V burn out the LED? I didn't think it would, but I wanted to look around and make sure. I couldn't find any definite answers.
