We have brighter lights and newer lights in the warehouse, yet the Aputure LS 300X goes out almost every week. It is not nostalgia: it is the COB fixture that solves most small and medium sets without forcing you to bring a generator or to worry about the electrical load of the house you are shooting in.

What it is, in two lines

A 350 W bi-color COB with Bowens mount, 2700-6500K range, CRI and TLCI rated by Aputure at 96 or higher. With the included Hyper Reflector the official figure is 24,300 lux at one metre at 4300K; fit the Fresnel 2X and you go past 56,000 lux. The head weighs 7.3 kg, the control box is separate, and you drive it with the 2.4GHz remote, the Sidus Link app over Bluetooth, or 5-pin DMX512 when the set is properly cabled.

Who it actually suits

  • Interviews and corporate: a perfect key inside a 90 cm softbox. Bi-color means you match window light or office fluorescents without swapping gels.
  • Shorts and music videos indoors: 350 W is enough to punch through a sheet of diffusion at two or three metres and keep the stop where you want it.
  • Documentary with a fixed set: five minutes to build, three to strike, one case to carry.
  • Cinematic weddings: controlled light for bridal prep, without asking the venue for a dedicated circuit.

Where we would not recommend it: daylight exteriors against the sun, or large interiors you need to fill through a window. That calls for something else, and we will tell you before you spend money.

Why renting beats buying

The LS 300X is discontinued: Aputure replaced it with the STORM 400x. In practice, buying one today means owning a fixture at the end of its commercial life that resells badly in two years. We keep it because it still performs on set and because the rental value is hard to beat: 35 € + VAT per day, 85 € for three days, 125 € per week, reflector, control box and cables included. If you shoot four or five times a year, the maths is not even a debate. We handle delivery and pickup across Abruzzo: L’Aquila, Pescara, Chieti, Teramo and the coast.

Three things you only learn by using it

  • Bi-color is a compromise, not magic. At the ends of the range (2700K and 6500K) output drops and rendering gets stiff. In our opinion the sweet spot sits between 3200K and 5600K: there the 300X is clean and you will not be fixing it in the grade.
  • The fan is there. It is well managed, but with an ambient mic in the room you will hear it. Move it away, put it behind camera, or shoot critical lines with the fan on low.
  • The control box needs a home. The cable to the head is not long: if the fixture goes on a tall stand, decide where the box hangs before you raise everything, not after.

If you plan to run it on battery rather than mains, say so when you book: we prepare the right power setup and charged V-mounts, so you do not discover the problem on location.

What we pair it with

The combination we rent out most often is the Aputure LS 600x Pro as key and the LS 300X as fill or back light: same family, same app, same control logic, so no time wasted making different systems talk. When we need hard daylight from off-camera we add the Nanlite Forza 720. On the camera side it works effortlessly with the Sony FX6, whose high base ISO lets you stop down and run the 300X through more diffusion. Ready-made packages are on our kit page.

Official specs on the Aputure site, while CineD has the independent tests that back up the numbers. If you are unsure which light your scene needs, write to us before booking: we would rather hand you the right fixture than the most expensive one.
