I don´t know if it´s interesting, but today one of my favourite sites
had this article:

Read and see for yourselves....

Walgreens is selliing little (about 8 cm long by 1.5 cm

lens work as a serviceable ring light? No ancillary power supply
would be needed. Of course, you would have no control of the
intensity except by varying the number of lights. I have an led
flash light that has tremendous intensity and range. It's too
big for this application, but the batteries (three AAAs) have
lasted for 1 1/2 years.
Another question. Could one photograph a white card illuminated
by led flashlights and get a rough idea of the spectrum by using
the computer's built in color analyzer? Photoshop will do the
same thing.

Guess I'll have to go to Walgreen's.......
My 4 LED flashlight powered by 3 AA cells finally started getting
less bright so I replaced the AAs....... Been about 2 - 2 1/2
years 0n the originals. The LEDs sure don't like power!
