What is the power consumption of an LED with bi color t1?

Dear Gang,

I have a bi-color t1 red/green LED that has 3 legs in it, I was wondering what is the voltage requirement and wattage that it can work with.Does anyone knows the answer?

Steve's given you typical ratings for one of those.
To work out what's what, connect a 470R resistor to a 9V battery and connect across different legs to see what lights up.  The resistor will limit the current to a safe 15mA or so.
Reckon on 20mA and 1.2..1.5Volts for a try out.
