Downloaded Photone on iPhone. Will have to play around with it once my other plant comes down. Does it work for LEDs too?
Photone can be used with a variety of light sources including a few different types of LED.

I've tested Korona /Photone and have traded email with the programmer on a few different topics. My take on it is that, overall, it's safe for a grower to use to get in the ballpark but, if you want consistently accurate readings, use a PAR meter (SPOT ON, LI-COR, or Apogee) is money well spent.
