dimming several small loads

[eucalor]

Hi!

 

I'm wondering if there is something like a dimmer pack with many channels (like 25, 50 or 100) that can dim small loads (like 25-60w). I'm thinking of making a wall or portal of lamps/bulbs and doing some simple cheesy animations/chases on them. I've got a few channels here that I can use, but they might have a problem with so small loads, also it feels silly to use loads of 2,5kW dimmers to power 50W lamps.

 

I've searched all over the net for a solution, and I know there has to be one, cause I've seen those walls, but I can't seem to find what is used to power them.

If it's standard light bulbs you want to use, then White Light's Digital Festoon System would work. I'm not sure if you can explicitly programme it, or if it just gives your prebuilt effects, but it can certainly do the cheesy stuff you want. Otherwise do you actually want to dim them, or would lots of relays on a demux work?

A French company, Chromlech were demonstrating a product called Jarag at PLASA last year. It's essentially a modular wall of light - 25 lamps in a case, with built-in dimming and DMX. Just stack them up to create the size wall you need.

 

It's very bright (as you'd expect with 1800W of PAR lamps, I suppose), and life on the ESTA stand (opposite Chromlech) didn't look like it was any fun at all...

Many dimming patterns are actually set up on four channel dimmers, or two 4chan packs set as a 4 x 4 matrix.

Would something like this work for you? 16 channels, DMX control 1.2 Kw per channel (but I think only about 300 watts per channel if all channels are loaded simultaneously):

These are built for the domestic Christmas and holiday market for those who go a little crazy with their lighting displays. you may have seen a video emailed around the Christmas before last of a house Christmas light display to the tune of "Wizards of Winter" They used something like this for that setup.
