NOHD depends on divergence too....

BTW, do you guys know that a 100W HID with tight collimation can blind as well within the first few tens of metres? (visible, UV and all). Short-arcs can still blind at farther distances. I'm looking at a 250W now with a 7" reflector, but I think its not that well collimated.

Here's a useful calculator.
