The moment a bag starts losing its shape is the moment it stops protecting anything. It happens quietly, usually around the fourth month, and it always starts in the dividers. Lights start sitting on each other, the foam compresses where it's been squeezed, and a lens that was fine for two seasons comes out scratched.
The three parts below are what we walk rental houses through before they commit to a pallet of padded DJ lighting bag stock. Three parts of the bag decide its life, and only one of them is the number printed in the listing.
Three parts fail, and foam is the one people overthink
Every padded bag in this category is foam, fabric, a divider system and a zipper. Buyers ask about foam thickness first because it's the only number usually published. In practice the failure order runs the other way.
Zippers go first, because a bag that gets packed when it's slightly too full loads the zipper on every close. Next are the dividers, which collapse inward when the walls have no structure of their own. Foam comes last, because even cheap foam does its job for a while, and it's the one part a customer can feel and judge instantly.
So when you compare quotes, ask what's inside the divider and what the zipper is rated for, not just how many millimetres of foam the listing mentions. That's a much better use of an afternoon.
Measure the fixture, then measure it again with the bracket on
This is the mistake we correct most often, and it costs buyers a whole container. A PAR fixture measured on the bench is not the same object as a PAR fixture with its bracket, clamp and power cable still attached. The bracket folded down adds height. The clamp adds width. The tail of cable adds depth if you're packing it in the same compartment.
Take the light you actually own, put the bracket in the position it travels in, hang a short cable tail off it, and measure the box it would fit in. Then compare that against the internal compartment figures rather than the external bag size, because the outside dimension of a padded bag is mostly foam and fabric.
The compartment sizes on our own range, so you can sanity check your numbers against a real product:
• QLB90 carries two lights plus a controller and cables, at 110 x 230 x 190mm per compartment, 250 x 230 x 190mm overall
• QLB80 carries four slim PAR lights plus controller and cables, at 80 x 250 x 200mm per compartment, 360 x 250 x 200mm overall
• QLB70 carries four slim PAR lights plus a controller, at 60 x 230 x 210mm per compartment
• QLB25 carries four PAR lights up to SlimPAR 64 or RGBA plus a controller, at 60 x 220 x 265mm per compartment
Those four shapes cover most of what mobile crews ask for, and each one is a separate product rather than a size option. The two light bag with the cable pockets is the QLB90 DJ accessory bag, the four light version is the QLB80 DJ equipment case, and the shorter compartments belong to the QLB70 padded lighting case. There's also a QLB25 PAR light case with the deeper compartment, which is the one that takes taller fixtures.
Slim PAR fixtures and full size PAR cans are not the same animal, and the compartment that fits one won't fit the other. If the model you own isn't listed, send us the fixture dimensions with the bracket folded and we'll tell you which bag actually closes.
Foam thickness is worth less than the divider core
Our bags use 10mm foam all around, which is on the generous side for this category. The more useful feature sits behind it. Each divider is reinforced with extra padding over a semi-rigid plastic core, so the compartment keeps its shape under load instead of bulging sideways into its neighbour.
That's the difference between a bag that still closes square in year three and one that has to be wrestled shut. It also matters when the bag is stacked in a van under other cases, because a divider with a core spreads the load and a foam-only divider just compresses.
Two smaller details do more work than they look like they do. Removable dividers let one bag change shape between shows, so a two light night and a four light night use the same bag. Rubber feet on the base keep the fabric off wet ground, which is what stops the bottom panel rotting out before the zipper goes.
The fold-flat trick, and why importers care
Here's the part that matters to anyone ordering more than a sample. A padded bag is mostly air, and air is what you pay for when you ship. Ours fold flat in the packaging, which cuts the shipped volume dramatically compared with a bag that arrives pre-expanded and stays that way.
For a distributor this changes the freight maths on a full container. It also means the bag arrives without the creases you get when a rigid bag has been crushed in transit for six weeks, so it looks saleable the moment it comes out of the carton.
If you're quoting a landed cost, ask your supplier to give you the packed, folded carton dimensions rather than the bag dimensions. Those two numbers can differ by a factor of four, and only one of them is what the forwarder charges you for.
Where the padding stops helping
A padded bag protects against the things that happen in a van. Scuffs, rubbing between fixtures, a dropped cable end, a light rolling into a door frame. That's what 10mm foam and cored dividers are for, and they do that job well.
What it won't do is protect a fixture dropped from a truss, and we won't tell you otherwise. If your crew is working at height, the answer is a hard case with an insert, and we'll say so rather than sell you a padded bag for a job it can't do.
One more honest limit. A bag doesn't dry a wet fixture. If lights come in from an outdoor show, they need to come out of the bag and dry before they go back in, or the foam holds the moisture and the contacts pay for it.
OEM, ODM and how a run comes together
The plant has been in Ningbo since 2009. Ten people work on design and tooling, and our gear ships to more than 60 countries. OEM is about the branding layer, so your logo, your cartons and your own model codes. ODM is about the build, which here means the compartment layout, the divider structure and the foam grade, all settled and tested before a run starts.
Alongside these bags we make the Yinyu cable range and the Yinyu stands that most mobile crews are already carrying, so a single order can cover the lights, the cable and the stands that hold them. We quote DDP, so the figure you agree to is the figure that lands. The padded bag range is built to order, so we confirm availability and dates against your quantity rather than promising from stock.
FAQ
Are the DJ lighting bags in stock or made to order?
They're built to order, so we confirm dates against your quantity instead of quoting stock we haven't counted. Tell us the fixture model, the carton quantity and the destination port and we'll come back with a landed DDP figure.
What is the difference between the QLB90 and the QLB80?
Capacity. The QLB90 carries two lights plus a controller and cables with a 250 x 230 x 190mm interior, and the QLB80 carries four slim PAR lights with a 360 x 250 x 200mm interior. Send us your fixture dimensions and we'll point you at the one that fits.
Does the bag fit a full size PAR can or only slim PAR lights?
The QLB25 and QLB80 compartments are sized around slim fixtures, while the QLB25's 265mm compartment depth suits PAR lights up to SlimPAR 64 or RGBA. Full size cans need a different layout, so measure yours with the bracket folded before ordering.
Can I change the compartment layout for my own brand?
Yes, that's standard ODM work. Compartment count, divider structure and foam grade are all things we change for a run, along with your logo and packaging under OEM.
Will a padded bag protect lights dropped from a truss?
No, and no padded bag will. The padding is there for transport, for scuffs and for gear rubbing together in a van. Working at height needs a hard case with a fitted insert.
Send us the fixtures you need to move
Send over the light models, how many travel in one bag, whether cables ride along, and how the cartons move, by van, by air or in a container. You'll get back a compartment layout that closes properly, packed dimensions you can hand to a forwarder, and a straight answer if a padded bag turns out to be the wrong product for how your crew works.
