Search for “Aputure LS C120d II LED light kit reviews” and you’ll find good explanations of output, mounts, and overall build quality. Search for the Aputure amaran COB 60x S and you’ll find the compact travel option. What I didn’t find, when I started building my own kit, was a side-by-side comparison that treated these two as real decisions. So this is that comparison.
When I first started booking small commercial gigs, I assumed the more powerful light was always the better buy. I bought the C120d II first. It looked professional. It also sat in my trunk for months because I didn’t always have time to set up a full stand and ballast. Then I grabbed a 60x S for a last-minute interview and realized the “little” light had been the answer all along.
This is not a sponsored post. I run a two-person commercial video operation, and I’ve used both fixtures on interviews, product shoots, and event content. I’ve made expensive mistakes with my own money, and I’ve kept notes so I don’t repeat them.
Why These Two Lights?
It’s fair to ask why compare a 60W compact COB to a 120W studio light. They’re not in the same power class. But in the real world, a solo shooter or small crew often builds a kit around either the Aputure amaran COB 60x S or the Aputure LS C120d II.
The decision kept me up at night. I went back and forth between them for two weeks. The C120d II offered the output and reliability I thought I needed. The 60x S offered portability and a smaller footprint. On paper, the C120d II was the safe choice. My gut said I’d use the 60x S more. After a year, I know both were right in different ways.
The dimensions that matter are output/light area, color consistency, portability, and system fit. Here’s how they compare.
Output and Light Area: The 4 Inch Recessed Lighting vs 6 Inch Problem
If you’ve ever been in the 4 inch recessed lighting vs 6 inch debate, you know a larger fixture isn’t just “more light.” It behaves differently. A 6-inch can with a wide trim floods a whole room. A 4-inch can creates a tighter pool and leaves more of the ceiling dark. These two lights work the same way.
The C120d II is the 6-inch. It gives you a wider usable light area, and you can move your subject around more before the falloff becomes obvious. With a softbox, it’s my first choice for a two-person interview. I can set it at a reasonable aperture and still have a convincing key even with some ambient spill in the room.
The amaran COB 60x S is the 4-inch. It’s a tighter source and easier to control. It’s enough for a one-person interview at close range, but when you need a broad soft wash, it runs out of gas faster. Not ideal, but workable. Exactly what you need for solo work, not what you want for a large set.
I made the “more power” mistake in September 2023. I brought the C120d II on a corporate shoot because I thought it was the safe choice. The location had no power near the interview area. I ran an extension cord across a hallway and taped it down. It worked, but I spent the day worried about someone tripping on it. The 60x S, with a battery grip and a small softbox, would have been on a stand in three minutes. That was the trigger event that changed how I think about output.
In practice, the C120d II has way more usable output. That’s not a surprise. The surprise is how often that extra output isn’t what saves the job.
Verdict: The C120d II wins the light area round. The 60x S wins when your area is small and your setup time is short. Choose based on the scene, not the wattage.
Color Accuracy and Consistency
This is the dimension where I used to be careless. I thought “daylight” was a fixed thing. Then I spent a weekend shooting product photos for a local brand and the whites were off. It wasn’t the camera. It was one of my budget lights drifting green as I dimmed it. The client didn’t complain, but I saw it. Output you can fix with exposure. Color drift you can’t fix without a lot of post-production time.
Pantone’s color matching guidelines give a useful target. A Delta E under 2 is the standard for brand-critical colors. Delta E of 2-4 is noticeable to trained observers; above 4 is visible to most people.
Industry standard color tolerance is Delta E < 2 for brand-critical colors. Delta E of 2-4 is noticeable to trained observers; above 4 is visible to most people. Reference: Pantone Color Matching System guidelines.
I expected the C120d II to be clearly better here because it’s the more expensive, studio-oriented light. In practice, the 60x S held its own. It’s not identical, and I’d still test both before a big color-matching job, but the smaller light is not a compromise.
What I mean is this: don’t treat the 60x S as a toy because it’s small. It held color through a 14-hour product shoot without me fighting it in post. The C120d II did the same.
Verdict: Tie. This was the most surprising round. A higher price tag does not automatically mean better color in modern LED fixtures.
Portability and Power: The Real Difference
The Aputure amaran COB 60x S is a light you can carry under your arm. I’ve flown with it in a carry-on. I’ve set it up on a small stand in a corner and left it there. It can run on a battery grip, which means no power cable to trip over. For run-and-gun work, that’s worth more than extra watts on paper.
The Aputure LS C120d II is heavier and wants to be plugged in. It has an external power supply, so there’s an extra brick to pack. Battery options exist, but out of the box it’s not designed for quick location changes. That’s not a flaw. It’s a job description.
I had a stupid moment last winter. I packed both lights for a two-day studio rental and left the C120d II’s power supply at home. The next morning, I used the 60x S for every shot because it could run on battery. The shoot went fine, but I felt like an amateur for carrying a light I couldn’t turn on. (Should mention: that incident started my pre-check list. In the past 18 months, it has caught 47 potential issues, including this one.)
Verdict: The 60x S wins for portability. The C120d II wins for continuous output and bigger setups. If you’re a location-heavy shooter, the smaller light will become your main light, and the bigger one will stay home.
Accessories and System Fit
Both lights belong to the same Aputure ecosystem. The C120d II has a well-earned reputation as a workhorse with a Bowens mount and a wide range of modifiers. The 60x S is smaller and lighter, which opens some doors and closes others.
Here’s the safety note: stick with Aputure or manufacturer-approved mounts and modifiers. I once bought a non-Aputure bracket to save about $40. It looked fine in the box. On location, the light tilted forward and nearly hit a hardwood floor. Nothing broke, but the sound it made changed my opinion on cheap mounts forever. The quality of the light doesn’t matter if the mount fails.
Oh, and before you buy modifiers, confirm compatibility with your specific mount, not just with the brand name.
Verdict: The C120d II has more system support. The 60x S is still part of the same family, but double-check every accessory. No single light covers every lighting scenario without the right add-ons.
So Which Aputure LED Light Kit Should You Buy?
Buy the Aputure LS C120d II if you’re building a studio kit and your jobs involve two-camera interviews, product tables, or any situation where a strong daylight key matters more than setup speed. It’s the light you use when you have time to do things properly.
Buy the Aputure amaran COB 60x S if you travel, shoot alone, work in small spaces, or need a light that can run from a battery. It’s the light that will actually make it into your car.
If budget allows, buy both. Start with the one that matches your current work week, not the jobs you hope to book next year. That was my mistake. I bought the “dream job” light and left it in its case while I flagged down extension cords. The normal light became the one I reached for every day. At least, that’s been my experience with a two-person crew.
For spotlight careers that bounce between studios and run-and-gun locations, the 60x S is the better first light. For spotlight careers rooted in controlled studio work, the C120d II is the safer anchor. If you’re still stuck on the 4 inch recessed lighting vs 6 inch question, apply the same logic: choose based on the room, the scene, and the job—not just the number on the box.
