Title: Fogger or hazer?
Post by: John Roll on August 28, 2011, 04:44:26 pm
Which or those devices will I need to purchase to create the light "beam" effect from my moonflower units?

Either will work, although you'll get better results with a hazer.

Foggers produce a cloud of atmosphere where hazers produce a fine mist which is usually preferable for beam fx

James is correct, and to add some details:
biggest factor will be cost. Cheaper hazers are normally either not true hazers or they don't hold up very well. Cheap smoke machines are still smoke machines, and may do what you want quite well.

Hazers are much more subtle, no clouds or "whooshing" noise. Smoke machines typically deliver a cloud which rises. Better machines have variable output and timer circuitry. Some, like the Antari Fazer emulate what a hazer does (kinda) but not really close to a real hazer.

Either type will trigger smoke alarms.

Get a hazer.
The problem with fog machines, unless you run them at 10% or less, is that you get a huge blast of fog which will often obscure the performers on the stage.

OTOH, foggers work far better outdoors (where hazers generally don't) or if there is a lot of air movement (e.g., massive A/C).

I've used a cheap ADJ hazer for years. Other than bypassing the ridiculous remote that was on it (so the box was always on), I've never had any problems with it and it's done a reasonable job.

One other benefit to a hazer is that it usually runs cold, so it doesn't require a 15-amp circuit all to itself as a big fogger would.
