We have, for the most part, sold the 6 Neutron's that we have had in our rental department over the past 3 years and replaced them all with Radiances. One of the biggest pet peeves that people had with the Nuetron, was the auto-cleaning mode when you start it and that they had to let it auto-clean before they turned it off. The only problems I have ever seen personally over the years with the Neutron was that the element is real touchy and the pump occasionally goes out. Neutrons are not bad hazers for your average, run of the mill
theatre. By all means an outdoor production it might take a few of them to get the results that you want, but I HIGHLY recommend the Radiance. As mentioned prior, it does have on-board
DMX as well as you can set your on-board dmx wheels to run by itself while adjusting the output and the fan speed. The Radiance is very quiet if you want it to be while producing still a great amount of nice, even haze.
We have a few DF-50's as well, and by all means those units do just fine, but they are pretty loud for a few of the smaller venues that we do. I remember how amusing I found it the first time I took the reservoir cap off the top and haze started pumping out of it.
Also, the Unique 2 Hazer is also pretty good. The first time we got to see it was last year at
LDI and then we quickly applied for our dealership. I would recommend either the Unique 2, or the Radiance, they are about the same price. (I defiantly lead more towards the Radiance).
The great thing about the Radiance is that about 75% of them serviced at our location is for the cleaning of the aluminum middle plate with ports that get clogged over time which is as easy as soaking it in hot water for half a day and simply wiping clean the ports. No need to replace it. The other 25% is the element that is in the bottom plate but we honestly don't get that problem to much even with units we have had sold for 2 1/2 years that use it at least 3-4 a week for about 3-4 hours a day. I by any means am not saying that it will never happen, lol. We have just had great experiences with the Radiance and have turned a huge number of our clients and touring bands onto them after letting them demo the units for a few weeks.
If you need more detailed information about these units, just let me know and I can post up the major differences in the units, videos we have made for customers and reviews we have had over the units.
