We don't have lots of W so are forced to make shit work. We get good results for outdoor parties of 600-1000 using 2 x 1.7w and 1 x 2w heads.
You just need to control the fog. And control i mean using fans and ducting. You cant rely on smoke machine's them selves and haze is good until the wind blows. You need to chop the fog, mix it with the air and throw it far. This can only be done by large fans.
Using just 1 look viper, 1 robe 1500ft and 2 x 550mm fans we have had fog spread evenly over a 50m x 50m dance floor with wind.

Sparks.
Nice presentation. Clearly high level pros, but nothing radical here...I think. OPSLs, as well as CGs showing multiple diode arrays with good thermal management. They admit to using large scanner mirrors and hence the lower divergence, but they made an interesting statement early on; they reduced the divergence 3X AFTER scanning. Was this a misstatement or a sloppy way to describe their 3x overall lower divergence? Maybe, but nothing about the spokesmen"s statements seemed otherwise sloppy. Any theories?

Its quite possible to place OPTICS after the scanners.
Seen that before. Takes really good engineering though...
Actually I do it to increase scan angle/effective scan speed at the cost of a slight increase in divergence.

Increased brightness but it must make safety harder to achieve when audience scanning as in their demo video as the tighter the beam the greater the irradiance. That's the only problem I see with the tighter beam to give a brighter show argument. Great for overhead and graphics but possibly more problematic for MPE purposes.

Just put the projectors way further from the audience to solve MPE problems :) I'm under the impression that Lobo doesn't make shows for less than 10'000 peoples... And you need at least these size of event to afford a Lobo show >:)

Steve,
Is it proportional as I had always thought? Place the scanners inside the telescope, double the scan angle, but double the divergence. Plus I would assume pretty significant aberrations from the scanned beams hitting the fixed positive optics. 3X after the scanners is pretty radical. If proportional they would need huge mirrors and huge angles from the scanners.
