Q. Hi,
I have pupils doing a school project on Planck's constant. Is it possible to get the wavelength of this LED?
A. Hi Ken, thank you for your question. Being a white LED this is measured in x y chromaticity which is x = 0.27 and y = 0.28.

Q. Hello, on these white LEDs, are the legs different sizes so that you know which one is positive or negative?
A. Hi Jack. Thank you for your question. On a colour LED the longer leg denoted the positive (anode) connection, however this is normally reversed for infra red LEDs.
