Pinspot Bars
« on: August 05, 2010, 02:40:22 pm »

Okay guys, time to build myself some new pinspot bars. How is everybody building theirs? I have decided that they will be built 4 and 6 to a bar, but that's about it. What are you using for the actual bar, how are you managing the cable to keep it clean, what are your rigging methods?

Going to be building a mix of all white and all black bars. Other details to consider: I need to be able to mount to 10' black pipe and base as well as airwall hangers.

Pictures much appreciated!

im building some soon. Going to use aluminum pipe, drill and tap for cable glands and wire it internally (like a 6-cir lamp bar). Im sick of seeing ugly unistrut pinspot bars.

Definitely keep me updated on that project. I've been trying to figure out an easy way to wire it internally but continue to run into issues trying to make it serviceable. Do you plan on using 1.5" sched. 40 aluminum pipe? or something with a thinner wall? Are you planning to drill and tap for the mounting bolt in the pinspot or thru-bolt it as on a standard lamp bar?

pinspots bolted through, just like a lamp bar (im actually doing this with par38 cans, but assembly wise it would be the same) its going to be a time consuming PITA to assemble these but the result will be well worth it. I wont be starting making them for a couple weeks, ill try to remember to update you.

What is a "pinspot bar"??? Do you mean ACL's? Sounds kinda DJish to me... Confused

Thanks Todd, looking forward to being kept in the loop. I'll be updating my progress as well once I perfect an internal wiring scheme.

Micky: I do not mean ACL's. I use pinspot bars to light table centerpieces and other event decor from pipe and base or other means of rigging. The extremely tight beam makes for an excellent "pop" of light to highlight whatever it is hitting while keeping light out of guest's eyes.

Nice lighting!

I wired my pinspot bars and used a small junction box to make it serviceable. I've seen others just zip-tie a power strip to the bar  Rolling Eyes

You can see the box in the pic:

I just use unistrut cut to about 24".  I can get 4 pinspots on one bar, which is just wide enough to allow focusing.  As for rigging, I use an airwall hanger when possible.  If I have to use a stand, I'll use either a drapery pole, or a 2" pipe and base.

put 4-6 on a 2' long 3/4" pipe wired in parallel (if 120v, otherwise in series) to a Uground or L5-20 connection with a couple of C-Clamps for rigging...and a safety Smile

I don't see the box.  Do you have another pic?  

Light rig looks great!  I'd like to see more pics of that, as well.

If you want to duplicate a "Real" par bar...

I am making a couple now, here are links to what you need:

>  Aluminum pipe, 2" OD 0.125 thickness T6061 minimum, Im using 90" length for 6 pars , or 5' for 4 par ACL bar
 http://www.onlinemetals.com/merchant.cfm?pid=4369&step=4 &showunits=inches&id=71&top_cat=0

>  Aluminum box to be welded onto the end with your choice of power-in
 http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en  &site=US&WT.z_homepage_link=hp_go_button&KeyWord s=377-1191-ND

>  Wire strain relief
 http://www.grainger.com/Grainger/HUBBELL-WIRING-DEVICEKELLEM S-Cord-Connector-2DPE4?Pid=search


my directions:
>drill a hole into the end of the gang box (big enough for your wires to fit through once welded to pipe)
>take it to a welding shop, (or if you can mig/tig aluminum) have the gang box welded to the aluminum pipe
>drill holes for wire inside pipe and run it to the gang box
>put strain reliefs on around cord and screw it into the tube (you can either tap the hole so its nicely threaded, or just drill it wider and put it through and seal with silicone)
> wire ends to input connector( in my case, a 19 pin socapex connector, but you can use powercon or a nema twist for single circuit or your multipin choice)
>wire bar ends to either lamp sockets or to edison or twist receptacles

I can make these for any type of conventional light, at any length, and I am thinking about making some for LEDs that have integrated DMX, so you plug both your powercon and DMX next to each other and then power and dmx is fed out along the bar.


just google thomas truss, par bar, or any other combo and you can get examples of what this would look like.
