Chauvet SlimPar Pro RGBA Review

Re: Chauvet SlimPar Pro RGBA Review

A question came up on the other forum about cases, and I tried (and failed) to post a picture describing the ones I made for my LEDs, and since I was planning to write about what I made anyway, here it goes.

My most important design goal was maximum density of lights. I first thought of building trays for EWI quarter pack road cases, but the dimensions didn't quite work out, and since much of my storage is off the ground and I don't own a forklift, I have to be careful how many unliftable cases I have. I settled on an 8-pack design with an accessory pocket.

I do van-level gigs where I'm the logistics, setup, teardown, etc., so I don't need ultra-heavy ultra-foamed cases. I settled on 1/2 Baltic with marine carpet padding - pretty much just wanting to keep the wood of the case from scratching the lights.

I built the outer shell first and used Festool Dominos and brads and glue to join the parts. The inner separation ribs I built separately and used a couple jigs to keep the position and spacing uniform.

I got the hardware from Parts Express. I made templates for the handles and latches on my Bridgeport and then used a router to cut the holes in the boxes.

Each box used around 48 sq. ft of carpet - I was really surprised, and didn't buy enough the first time around. I used a putty knife and carpet glue to hold the carpet on, with a couple staples in strategic hidden corners to hold the carpet while the glue was curing.

Total material cost was around $300 total for the wood, Parts Express hardware, carpet, and a gallon of Duratex, of which I used about 1/3 for the two cases I built like this.

This was my first use of Duratex, and while it sure goes on easy, I already have to touch up a little bit of it where something else in the gear pile rubbed over a small drywall mud fill I did. It's unfortunate that wood fillers are incompatible with Duratex, as drywall mud doesn't have much structural strength.

Overall I'm reasonably happy with how the cases turned out. I like the form factor - it works out to around 24" X 20" X 12", and that includes a 5" accessory pocket that's large enough for the power cables, 5' DMX jumpers, safety cables, and the ring clamps I'm using. The case is fairly heavy - empty it's about 45lbs, filled with lights probably 110lbs.

Re: Chauvet SlimPar Pro RGBA Review

Where did you see that?

btw, Very nice build there.

Thanks - they're not perfect, but it was a good project for refining my woodworking craft. The biggest issue I had (and pretty much the only issue) was that I used 1/2" for the plywood thickness in my dimensional calculations, when it was more like 31/32". I didn't think that it would matter, but it actually did, as inside pieces were slightly too short. Since the Dominos reference off the edges, that meant I had a little gap to fill.


The Duratex instruction sheet recommends drywall mud rather than wood filler due to adhesion issues:

Based on my experience, I think drywall mud can work for filling a crack between pieces, but I used it to fill in a countersunk screw hole where I reinforced the wood near the front handle, and that's one of the places that got torn up. When I get around to repairing it, I think I'm going to try water putty or even Titebond, as it's hard to do worse than drywall mud - even if adhesion isn't perfect with something else.
 
Re: Chauvet SlimPar Pro RGBA Review

I use wood filler and have had no issues.
I wonder if it's an issue of the surface being rough enough (open pores for it to cling to)
I sand everything w/60 grit sandpaper so the duratex has a texture to grip to.

You could always use wood filler and then prime over the filled areas.
Then the duratex would be sticking to primer, not wood filler.

TJ, nice write up.
I'm using a bunch of 300w Par56 for front lighting...usually with a light salmon gel or not gelled at all depending on the LD. Do you think these LEDs would keep up to them in this application?

Also with the Duratec- use whatever filler you like and then a primer before painting. I use bondo, and Duratec sticks fine to it as long as primer is used.
 
Re: Chauvet SlimPar Pro RGBA Review

Not at all not a single led is at this point capable of soft colors. Leds ares still pretty restrictive to intense saturated colors.

Poorly made LED fixtures are pretty restrictive to intense saturated colors, as they don't do such great color mixing. Take a look in a higher price range. Have you tried any RGBAW fixtures?

Yep.

Sorry, it was quick replies while riding levels at a bar gig. To expand on my earlier posts; So far etc with the seledor series has gotten closest. It still looks different compared to an incandescent but with as much as your gonna spend on a fixture like that, get a demo unit to do a side by side shoot out.

Sorry for the slow reply - I just got done working a 100 hour week at a large gig.

Generally I agree with the other responses. LEDs are really good at what they're good for - huge saturation, power efficiency, multiple colors, non-traditional form factors (flat pars, etc.). They're less good at softer tints. It seems in your application that you're looking for a primarily white fixture for front wash. If that's the case, you may have some success with one of the variable white style fixtures. The ETC Selador line has a couple - both fixed color temperature and variable, and others do too. The sister fixture to the Chauvet SlimParPro RGBA the SlimParPro VW would be better suited to your application, and it actually ships with a gel frame so you could still use your warming gels if you want. I haven't personally tried that model. I'd like to, but it's pretty low on the gear lust list.

Note that with white fixtures, you lose many of the advantages LEDs bring, as it's gelling conventional fixtures that really kills the output and makes them inefficient. I did the math a while ago so my numbers are from memory, but believe it takes about 4 Chauvet VWs to get close to the brightness of a 750w Source Four fixture, so your fixture count certainly wouldn't go down, and might actually increase.
