quote:It appears LED's don't have as well defined "beam" as non-LED fixtures, but still look good through the haze.
This is because LEDs are a wash fixture and not a spot fixture (minus the few spot LED fixtures out). All wash fixtures in haze will look more like clouds of color vs spot fixtures which will make tight beams. Also note that the stronger the intensity of the light, the better the beam. Remember when I mentioned angles to you before? Well, its much easier to see when the room is hazed. So, in order from weakest to strongest, front light, over head light, back light, side light, high side light, and finally on the deck shooting up over the stage/audience. If you notice on a few shows I have done, I put 250w movers on my back truss and 575's on the deck, because the 575's cut better. On the even larger shows I am doing now, I am doing 700/1200w movers on the deck with 575/700w movers in the air.
Here is a picture to better show what I am talking about:

In this picture, the 8 lights on the deck are DLED 36 MHs and the two lights projecting the blue stars are DS 575 E's. Notice how a few feet up, the DLED 36's lose there power to 'cut' the haze. All the way up in the air, however, once their beams have joined together, they create a cloud. The ones on the end, however, just fade away.
Likewise, the 575's, with more power, better angle, and sharp beams, cut through the haze all the way to the floor. When I have had those on the deck with frost filter in, they create a much better, bigger cloud then the DLED 36's do.
