Re: Introduction: Introduction to Voltage & Current Control Electronics for LEDs

NO RATINGS
"How much would you derate an electrolytic?  Eg - if you had a 50V circuit application, would you utilize a 75V cap for a consumer lighting application, or would you go up to 100V?"

If you are sure the circuit never goes above 50V (even during lightning, when LEDs are in cold environment, etc.) then 63V is fine. Spend the money on higher temperature rated components.
