Aputure has opened orders on the STORM CS32, a 3,200W BLAIR CG point source that claims 4K HMI output from an ordinary wall socket, with a 19.8kg / 43.65lbs lamp head and a silent mode that drops the draw to around 550W. We spoke to Brandon Le at the company’s IBC 2026 booth about cooling, circuit safety, and why every XT52 optic bolts straight on.

The CS32 was previewed at NAB back in April, but IBC is where it became a product you can actually buy, with pre-orders available now. Aputure positions it directly underneath the STORM XT52, the 5,600W monster that needs three-phase thinking and more than one person to rig. The CS32 keeps the full color engine and most of the output, but plugs into a normal outlet in North America, Europe, or Australia. Brandon took us through the parts a spec sheet leaves out, including what silent mode really costs you and what happens if you pull a live cable.

A 3,200W point source that runs off a wall socket

The headline number is 3,200W of maximum power draw, with a maximum light output rated at 2,600W. Brandon’s comparison was to traditional discharge and tungsten fixtures: a 4K HMI equivalent or a 10K tungsten equivalent, whether you are running the reflectors or the Motorized CF16 Fresnel. That is the company’s claim rather than a measured figure from us, but the photometrics give it some backing. With the 30° reflector that ships in the box, Aputure quotes 35,500 lux at 5m / 16.4ft at 5,600K, and 103,000 lux at 3m / 9.8ft at 3,200K. Bare bulb, at the native 78° beam angle, the same 3m distance gives 14,800 lux at 3,200K.

The 30° reflector is new and specific to the CS32. The point of it, Brandon explained, is to pull as much usable output as possible out of the fixture at a beam angle that suits the way the light will mostly be used, which is indoors rather than blasting through a window from a lift.

What extended red adds to BLAIR CG

The CS32 uses Aputure’s BLAIR CG light engine with extended red, which puts blue, lime, amber, indigo, red, cyan, and green emitters behind one lens. Brandon spent most of the interview on the two ends of that spectrum. The indigo emitter reaches into the short wavelengths where optical brighteners in wardrobe fluoresce, which is what keeps whites looking clean rather than dull. The extended red sits at the far end and does two jobs: it deepens saturated reds when you are mixing color, and it puts warmth back into skin tones that narrower engines tend to flatten.

The measured white light performance backs that up. Aputure quotes SSI scores of 93 against tungsten (P3200) and 91 against daylight (D5600), a CRI of 97, a TLCI of 98, and TM-30 figures of Rf 96 and Rg 100. The CCT range runs from 1,800K to 20,000K, with more than 90% coverage of Rec. 2020 for saturated work.

What was more interesting was the design philosophy behind the saturated colors, because that’s where standards get thin. Aputure’s approach, Brandon said, is to simulate what a gel does on a tungsten or HMI source rather than simply firing every emitter at once. That drives choices at chipset level, down to which nanometer the amber or lime emitter sits at, and the practical payoff he pointed to is in the warm end: CTO, straw, golden hour, and sodium vapor looks that are harder to reach on engines built purely for saturation. Those colors are reachable through the onboard HSI, RGB, and x/y controls, so the light does not need a console to get there.

Vapor chamber cooling and a head one person can rig

Getting 3,200W into a body this size came down to cooling. Aputure uses vapor chamber cooling here, all air-cooled with no liquid loop, and the result is a lamp head of 19.8kg / 43.65lbs with the yoke, or 16.8kg / 37.04lbs without it. The control box weighs in at 10.8kg / 23.81lbs.

Brandon described the CS32 as a shrunken XT52 and put the saving at seven or eight kilos. Aputure’s own published figures are actually more generous than that: the XT52 head weighs 31.3kg / 68.56lbs with its yoke, so the gap is closer to 11.5kg / 25.4lbs, with another 2.6kg / 5.7lbs saved on the control box. The design target was explicit, and it is the reason the number matters more than usual: one person should be able to get this head onto a stand without help.

How quiet does it actually get?

This is the part of the conversation that will matter most to anyone working in a studio or a practical interior. Brandon framed the two fixtures by where they end up: the XT52 goes outside the window, the CS32 goes in the room. Sound therefore became a design constraint rather than an afterthought.

The fan runs in silent, low, medium, high, and max modes, plus a smart setting that modulates as needed. Aputure’s measured figures at 1m are 24.3dBA in silent, 31.3dBA in low, 40.2dBA in medium, and 52.4 to 52.6dBA in high and max. Brandon’s guidance is that medium is the setting you live in, and that it will hold up to an ambient temperature of 35°C / 95°F before you need to move up. Silent mode is the one with a real cost attached, because the fixture caps its own power draw at roughly 550W to keep the fan crawling. That is around a sixth of the maximum draw, so a room quiet enough to record dialogue in comes at the price of most of the fixture’s output. Low mode sits between the two, with a far smaller penalty.

Circuit limits and what happens when you hot-plug

The CS32 runs on 100V to 240V at 50 or 60Hz, and the interesting engineering is in how it protects itself at both ends of that range. At 230V, a full 3,200W draw works out to roughly 14A, which is comfortable on a 16A CEE circuit but sits right at the edge of a 13A domestic plug. Brandon’s advice for that case is simply to turn the fixture down, and the power and output menu lets you cap the overall wattage of the system so that it never exceeds what the circuit can give.

North America gets a more automated version of the same idea. A second cable option flips the fixture to a 15A or 20A preset, limiting it to roughly 1,700W or 2,200W, and either can be set as the default so the light is always inside the circuit’s capability. Aputure’s own documentation notes that the household Edison cable caps brightness at 80% on a 110V 20A circuit.

The second safety layer is mechanical. Both the AC power cable and the lamp head cable use a two-stage connector. Unplugging the first stage cuts power before the second stage separates, so pulling a live cable does not produce an arc. Brandon was refreshingly blunt about why it exists: Aputure does not recommend hot-plugging, but users do it anyway, so the connector is designed to make it harmless. As with the rest of the STORM line, from the STORM 400x and the 80c up to the XT52, both the head and the control box are rated IP65.

Every XT52 optic fits

Compatibility was the point Brandon returned to most often. The CS32 uses the same Aputure mount as the XT52, so the 20, 25, 35, and 50° XT52 reflectors all work, alongside the new 30° CS32 reflector. The Motorized CF16 Fresnel fits, as does the STORM Parallel Beam 70, which uses a Cassegrain optical design to squeeze the beam down to 5° for long throws. There is also a skid, an air deflector, and head cable extensions that take the run out to 45m / 148ft.

New at the show, and sitting on top of the booth, was the STORM A-Mount Lantern 180, a 180cm lantern that works with both the CS32 and the XT52 for large soft sources and moonbox setups. Control runs through the onboard menu, Sidus Link over Bluetooth, DMX, CRMX, and Art-Net or sACN. Brandon made a point of the DMX profiles matching across the STORM and Nova families, which is the kind of detail that only becomes visible in a broadcast environment when two fixtures set to the same HSI values need to actually produce the same color.

Price and availability

The STORM CS32 is available now for pre-order at around €7,000, with the flight case version a few hundred euros more. US pricing is $6,990 for the standard unit and $7,590 with the flight case. The Motorized CF16 Fresnel adds roughly €2,600 to €2,700 depending on whether you choose the soft rolling case, hard rolling case, or flight case, and is listed at $2,690 in the US, which puts a complete head and Fresnel kit at around €10,000. Shipping begins in October. For more information, please see the Aputure website.

A 4K HMI replacement that plugs into the wall is a tempting proposition, but does the silent mode trade-off work for the way you shoot? Don’t hesitate to let us know in the comments below!
