Odd Moving light suggestions please.
« on: March 23, 2009, 03:50:40 pm »

I have been out of the lighting business for quite a few years and a lot has changed.  So I am looking for some input on current fixtures-I prefer not to go the used route.

So here is what I am looking for:

Either rotating mirror or rotating yoke units-no real preferance.

I only need white (but yes, all the other colors come for free Laughing) -basically saying I don't need a pile of colors or mixing.

I would prefer an adjustable iris (like a spot light) but could possibly live with a couple of gobos that are various sizes and are round in shape.  It does not need to have rotating gobos-yeah like that would do any good with a ROUND gobo Shocked  Laughing

Does not need to be a high brightness-so most smaller wattages would be fine-I don't need to cut through a bunch of smoke or bright stage lights.  I am just looking for something to spot objects in a normal lite room about 40' away.

So basically a simple low wattage unit with an adjustable iris (yeah-that is probably the hard part) or multiple round gobos.

I do not need it to spin all the way around-a 90

I don't know of any moving lights with irises that use smaller than a 575W lamp, which is likely overkill for your application.  

Another approach would be to build what you need using readily available components.

Something like a Source 4 + a Rosco I-Cue + a DMX Iris + a dimmer (a BakPak dimmer will work).

This is assuming that the 19 degree Source 4 has enough output for what you want.

WOW- being the DIYer that I am, that may be just the ticket I am looking for.

I don't care about looks and it will get treated gently.

THANKS!

Ivan, I've done several projects over the years similar to what you are looking for. The low$$ fixtures will probably be bright enough but the resolution of the p/t motors may be an issue if you're looking for pin-point accuracy. Definitely won't find an iris on anything less than a 250w discharge (Design Spot has an iris), but you'll either need something with removable gobos or just find the right size and glue it over the "open" position.

If you're not opposed to used fixtures, a Trackspot might fit the bill; it's got decent p/t resolution and it has one removable gobo slot.

If you want a moving head, and need hi-res p/t, the Design Spot is just about the only choice with an iris. If you don't need hi-res p/t, an ADJ AccuSpot would be a good choice with the replacement gobo idea; AccuScan if you can use a scanner instead.

Any of the low$$ fixtures will use 8 or fewer channels.

The standard Trackspot gobo wheel has one removable slot. I have some wheels that have 4 removable slots. I can't remember where I got them.

And of course you could get a custom wheel with all different sizes of circles (or any gobos you desire)

Plus, Trackspots are only 7 DMX channels!

Craig, I used to have 4 wheels with all open slots. Came out of some fixtures that were used in a dance studio, and had a whole bunch of break-up gobos in 'em. When Core shut down, I tried to grab everything that might prove useful later before it all got pitched in the dumpster, but I'm not sure if I still have the wheels.

We used to do some strange things with custom gobos, broken dicros, and clear RTV, especially on older IBeams......

That said the Rosco option will let him use a very robust fixture with common and cheap lamps and have only 4 channels of dmx control. It is true that it is more cabling and more individual pieces, but by the same token it also helps ivan in that so long as his physical layout is the same time and again he can get his presets in the right ballpark by simply physically moving the fixture.

I love ETC fixtures.....

Maybe a revolution with an iris motor? Although that would more than likely have to high of an electric draw

Otherwise the Design Spot would be a good option.

I don't need really fine resolution and the gobo or iris would in most cases change size with each position.

The light will not be moving a whole bunch-maybe just a couple of hundred (or much less) times a day.  Think stay in one position for a couple of minutes and then move to another position for a couple of minutes and so forth.  No sweeping or other typical moving type functions.

Thanks for all the insights-I am going to look at a couple of different options.

8 bit movement at 40' or so can literally mean each step moves the circle 4 feet at a time. So I would think it IS important Smile

See that is just showing off my ignorance of the subject Embarassed .

The distances may be shorter, but I am thinking between 30-40' in general.  I may need to modify my overall thinking of the layout.

So exactly what is "8 bit movement"? Is it 8 steps through out the full sweep range?

I have been out of lighting for a while and a lot has changed.
