Aputure Amaran 100x LED Light Review (2026): The 100W Bicolor

Why you should trust this review

I have been reviewing lighting gear for 11 years, and I bought this Amaran 100x at retail in August 2025. Aputure did not provide a sample and had no involvement in the review. That independence matters in a category where output and color claims are routinely inflated, and the only way to cut through it is to measure.

Over nine months I used this light on roughly 50 paid product, interview, and short-film sessions, and tested it against my own Aputure 200x S and a Godox SL-60W on the same subjects under identical conditions. Everything below comes from a spectrometer, an incident meter, and real shoots rather than the spec sheet, because a light either holds its numbers in front of a meter and a paying client or it does not, and nine months on the job is enough to know which.

How we evaluated

My protocol leans on instruments. For output I took Sekonic L-858D incident readings at 1, 2, and 3 meters at every 500K step from 2700K to 6500K, so the numbers reflect the full bicolor range rather than just the headline daylight figure. For color I ran Sekonic C-800 spectrometer measurements and averaged CRI and TLCI across the color range, which catches lights that hold accuracy at one temperature and slip at others.

Fan noise I measured with a decibel meter at 1 meter at 25, 50, 70, and 100 percent power, because a quiet light on paper can still be audible on a sensitive mic. And to test longevity I tracked 200 hours of run time for output drift and color shift, which is the failure mode that quietly ruins a cheaper fixture over a working year.

Output: honest to spec across the range

At 5600K and 1 meter the Amaran 100x measured 2,420 lux, within 2 percent of its published 2,500 lux spec. That close agreement is what you want, and it means the daylight output is real rather than optimistic. For the 100W class, that is a genuinely usable amount of light for product work, interviews, and short film at typical working distances.

Because it is bicolor, the more useful test is how it behaves across the whole 2700K to 6500K range, and here the honest note is that output drops about 8 percent below 3200K. That is normal for bicolor LEDs in this price band, since the warmer emitters are less efficient, and it is worth planning for if you do a lot of tungsten-matched work. For comparison, the Godox SL-60W managed 1,840 lux at 1 meter, so the Amaran puts out roughly 30 percent more light while adding bicolor flexibility the Godox lacks.

Color accuracy: where it earns its keep

Color is the strongest part of this light. CRI averaged 96 and TLCI averaged 97 across the full 2700K to 6500K range on the spectrometer, which is excellent for a fixture at this price and the reason it integrates cleanly into professional work. Skin tones and product colors come back accurate, so the grade is about creative choices rather than fixing the light.

Crucially, that accuracy holds across the color range rather than peaking at one temperature, which is what separates a serious bicolor light from a cheap one. An unbranded 100W LED in my comparison claimed strong numbers and measured CRI 82 in practice, a gap you absolutely see in skin tone. The Amaran 100x is the kind of light a solo creator can trust on a paying job without second-guessing the color, and over nine months it never gave me a reason to.

Fan noise and build

Fan noise is the make-or-break spec for interview lighting, and the 100x handles it well. Up to 70 percent power it stays under 30 dB at 1 meter, which is below the noise floor of a typical lapel microphone in a quiet room. In practice that means it is inaudible on a seated subject’s lav mic, which is where I use it most, and I rarely need to push past 70 percent for a single-subject setup.

At full power the fan climbs to 38 dB and becomes audible on a sensitive shotgun, so the workflow is the same as with any quiet-but-not-silent fixture: keep it at 70 percent or below for dialogue and you are fine. Build quality supports the working use too. The chassis is solid aluminum, the yoke locks firmly, and after 200 hours of run time I saw no output drift, no color shift, and no fan rattle, which is exactly the longevity you want from a light you depend on.

The modifier ecosystem advantage

The Bowens S-type mount is quietly one of the best reasons to buy this light. It accepts the full Aputure modifier lineup, the Light Dome, the Spotlight Mount SE, Fresnel attachments, plus essentially every third-party Bowens softbox and reflector I own. That means the 100x is not a sealed island, it slots straight into an existing kit and grows with it.

For a solo creator, that ecosystem is what turns one light into a flexible toolset. You can soften it through a dome for an interview, snoot it for product separation, or run a Fresnel for a hard key, all without buying proprietary accessories. The two honest limits to weigh against that flexibility are that the power supply is an external brick rather than internal, and there is no app control on this model, only the rear dial. Neither is a dealbreaker, but both are reasons someone might step up to the 200x S.

Who should buy the Aputure Amaran 100x?

Buy it if you shoot product, interview, or short film at the 100W class with a Bowens modifier kit, you need bicolor flexibility from 2700K to 6500K with CRI 96 plus, and you want a fan that stays quiet enough for a typical interview set. It is also the right pick if you value the Aputure modifier ecosystem over a sealed proprietary mount.

Skip it if you need app control or pixel effects, where the 200x S adds those, or if you shoot mostly outdoor daylight fill, where a daylight-only Godox SL-60W at half the price is the smarter buy. Skip it too if you need an internal power supply for tight rigging, since the 100x relies on an external brick.

The verdict

The Aputure Amaran 100x is the bicolor light I trust first for solo work, and nine months of paid shoots plus instrument testing is why. Output is honest to spec, color accuracy is excellent and holds across the full range, and the fan is quiet enough for dialogue at the powers I actually use. The external brick and missing app control are real but minor limits, and the Bowens mount makes it endlessly flexible. For a creator building a 100W-class kit on a budget, it undercuts every direct rival and earns the recommendation.
