edit: both LEDs just fried. what is going on??

My guess is that you had a wiring fault that you haven't found yet. The other possibility is that both of those LEDs require a higher than normal forward voltage, but that is unlikely.
they're in parallel...with one 120ohm resistor for both
That seems like wayyyyy too much current for those LEDs
thanks so much for all the replies...here is a png of what i had wired up:
It's been working fine for a few hours but i do need this to work for around 7 hours a day for a month. you think it'll be okay?
