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. 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. The colour wavelength of this is 8000k approximately.
Q. I am looking for some bright white leds for a school project, the students are making lanterns. Would this one be suitable?
A. Hi Chris, thank you for your question. These TruOpto 5mm white LEDs would be suitable, there are 3 brightness levels in this range.
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.
