Strobes man... Strobes.
Xenons are probably bright enough enough but it's the other issues... Moisture, lack of randomness, and cost. I was half tempted to try some xenons this year but I was glad I didn't since it was a very wet season for me. I don't think t here is any argument that the xenons will outperform led options but not without the aforementioned issues.
Initially I wondered if there was a way to create a system that uses 3 dmx channels to control speed, randomness, or duration. The Aussie folks have a couple of options just thought we could too.
