Phlatlights

In 2012, I bought several of these from the USA. My intention was to use these very powerful LEDs in my experiments with 481THz light communications over the horizon having had great success with QRSS over the horizon with far less powerful LEDs. 

Then I had my stroke and I was just too wobbly for field work. They are still in the shack drawer! It would be great to use these as I am sure much further non line-of-sight would be possible.
