measuring light levels.

[bil]

Took me a while to work out what the question is I wanted to ask.

I'm trying to establish a good place for my Phals, in the 1,000 to 2,000 fc range.

Now the problem is for me in measuring the light levels. In the full daylight it's 9 to 10,000 fc. In the full shade, no matter how bright, it's only 500. Ok, that's simple with my new toy, a light meter.

However, the dappled shade is a problem. It consists of bits of shade which show 500, but then if you move it so that the detector is in a brighter area, the reading is much higher.

So how do I estimate what the light levels there are please?
