    I have a few LED PAR 56's and I need to find an idea, for gobos for these lights. I have a costumer who want's a tree like gobo or vine like gobo to spread on the walls of her wedding and we have the led pars, but I can't find anywhere that makes gobos for 56 par cans. I know any gobo for any 56 par will do but I am having the most trouble finding companys with gobos that big. Cost isnt that much of an issue, but I would need to get this figured out ASAP. If not a actual gobo any other ideas?

    You can not put a gobo in a par56. In order for a gobo to work, you need to use it in an ERS style light such as a Altman 360q or a ETC Source 4. A gobo works by cutting out the light a the focal point of the reflector. The focal point of the reflector of a PAR is not reall accessable to do this with, nor is it controllable. You will need to buy some ERS fixtures in order to get this to work.

    Yeah, you will have to buy/hire one. Consider the Selecon Pacific, I have these, they are great lights, especialy as you can make your own Gobo's. You simply print it onto transparent OHP paper.

    More info is on there site, here and more info on DIY Gobo's here giving you all the info you need, if you wanted to do this on a ETC Source 4, you would need a lazer cut gobo & gel, or a glass gobo, both are expensive.

    Going a bit off topic here, LED ERS's? Is this possible? Do they exist?

    You can take a trick from film/TV and use a cookie, but it probably isn't the best solution for the type of event you are doing. Basically a cookie is a pice of material (usually plywood) that you cut a breakup into and put a little bit in front of the light. It won't give you a sharp edge, but it will breakup the light and give you some shadows to play with. It works, but it is bulky and not very pretty to look at the setup.

    It's not possible because if you try to put any sort of shape in front of a PAR which is a WASH fixture you will just end up with a blurry mess!!

    As said you will need a profile for eg. Source fours etc...

    I can second the recommendation for the Selecon pacifics they are awesome fixtures and the gobo's can just be printed again and again!

    Yeah, Source Fours are great fixtures, but if you do want to make your own Gobo's, and belive me it can be a lot easier than trying to find the ideal ones, then the Pacifics are for you.

    Don't bother sinking the money into the Selecon's for a one-off wedding. Go rent some S4's and buy some tree breakups, that'll do the trick. Use the LED Par 56's as uplight right under the surface you're projecting the trees onto and they should act as fill around your trees (pending what gel you slap on the S4's)

    No, if it is a one off thing then definatley go and hire a Pacific. And a dimmer pack. That will also eliminate the need for LED's, and PAC's aren't too much more expensive than your Source 4's.

    In all probability it will be 10x easier to find S4's than Selecon's from rental houses. I don't know of too many that carry them. Many of the big boys, like 4Wall, don't even carry them.

    Metal breakups are really not expensive and can be reused.

    If you own the LED pars might as well use em' in the method I mentioned previously. There should be a decent amount of wall sockets in the reception hall.

    True, I'm in Aus, and Selecon is based in NZ, so they are common here, so what about my question on LED ERS? Possible, my PACs are all in use at the moment, but as soon as they come down I would like to try my idea of sticking a LED on the bottom and seeing what happens.

    In short, it won't do what yo want it to. Has a lot to do with who LEDs are design and how they work and the fact that your ERS fixtures are not designed to deal with that. It probably isn't worth the time it will take to test it, but that is a discussion for a new thread.

    We have several people here pushing you to rent a Selecon to fix your problem. If you are in the UK or Down Under then that's your best bet. Selecons are excellent but here in the U.S. they are more expensive than the competition, reflect a different design concept (we typically use fixed focus lenses here, they use zooms), and are just hard to find because they are new to a market already dominated by ETC products.

    So if you live in the U.S. you will want to rent either an ETC Source Four or an Altman 360 (The Altman is the old workhorse of the industry. It will be cheaper to rent but won't have as good of an image quality as the Source Four). The person renting it to you will need to know what size lens you want or you will have to pay extra to rent a zoom. Measure how far it is from the lighting position to the place you want the image projected. The place you rent from should have a selection of gobos on hand to purchase. They will most likely be from either Rosco, Apollo, or Gam. You can check out the options online from those catalogs. You probably just want to purchase standard steel gobos... glass, color, and custom gobos get VERY expensive.

    Where are you at in the world? Do you need help finding a dealer to rent from?
