To Burn, Or Not To Burn...

[hosshead]

....that is the question!

So many orchids require HIGH light to bloom*, I've read remarks that, if you want your Ansellia to bloom, you must resign yourself to leaf burn, it requires so much direct light.

So, how much burn do we generally accept, what do we think about Ansellia and how to give enough light without severe burn?
What about catts and direct sun?
Especially at high latitudes?

Some of the finest flowering orchids I've seen had some moderate leaf burn.
Then again, many don't.
Lower latitude orchids seem to get enough light year-round that they don't need direct sun....

I'm interested in the highly respected opinions of this forum, now it's summer and my mind turns to this question every year.

*Of course, we are not talking about the shade-lovers....
