My application is for illumination in slide viewers. However, somebody
at my client's office has made a hologram for the company logo. When I
look through it at a white LED a few feet away I can see the company
logo. So, I do not know if you can make a hologram with a white LED but
you can sure view a hologram with a white LED.
