Hello everyone,
I want to build a color changing lightsaber like this one in the video.

However, I don't know what LED did he use to do that. Does anyone has any idea what kind of LED do I need to make a color chaning lightsaber? or what kind of flashlight did he used?
I tried to email him, but he did not reply at all. I hope one of the experts in this forum can help me.
Thank you
