Looking for suitable LED manufacturer..pls help!!

Currently i am doing solar project. I am looking for suitable LED with small forward current that will increase the capacitor discharge time during the night. So far i have go through the LED product of OSRAM, NICHIA, and VISHAY. Can any guy suggest or give me the name of other LED manufacturer? Thanks :lol:

???? I cannot understand what you're trying to do at all. Increase the capacitor discharge time??? What does this have to do with a solar project and how does an LED work in there?
