The Aputure Amaran 200d S (£329) delivers 260W with 65,500 lux at 1m; the Aputure Amaran 300d S (£499) delivers 350W with 98,000 lux at 1m. Both are daylight-only COB lights with CRI 95+, Bowens mount, and identical app control. The 300d is 50% brighter than the 200d, justifying its 50% price premium for specific use cases. For most creators, the 200d S is enough. For those who push light through large modifiers, shoot from further distances, or mix with natural daylight — the 300d S is worth the step up.
This comparison helps creators choose between Aputure’s two prosumer COB lights. For broader lighting context, see my Ultimate Creator Equipment Guide 2026.
Quick Verdict: Which Should You Buy?
- Buy the 200d S if: You shoot in small-to-medium studio spaces, use medium-size softboxes (35-60″), subject is within 2m of light, or you’re on a tighter budget. This covers most creators.
- Buy the 300d S if: You use large softboxes (60″+), shoot subjects 2m+ from light source, mix light with bright window daylight, or need headroom for shaping with multiple diffusion layers.

Understanding the 50% Output Difference
The 300d’s 50% brightness advantage (98,000 lux vs 65,500 lux at 1m) represents approximately 2/3 of a stop of additional exposure headroom. In practical terms:
- Same scene exposure: 300d can be used at ~65% power where 200d requires 100%
- Through heavy diffusion: 300d retains usable output; 200d can feel dim
- At greater distance: 300d reaches further with same quality
- Mixing with daylight: 300d overcomes brighter ambient light more effectively
Stop values matter because light falls off quickly with distance (inverse square law) and with diffusion (each softbox layer eats 1.5-2 stops of output).
Real-World Output Through Modifiers
Both lights lose similar percentages of output through modifiers, but the 300d’s higher starting point means more usable light reaches the subject.
Through 35″ (small-medium) softbox
- 200d S: ~15,000-18,000 lux at 1m on subject
- 300d S: ~22,000-27,000 lux at 1m on subject
Both usable. 200d at 100% vs 300d at ~65%.
Through 60″ (large) softbox with inner diffusion
- 200d S: ~5,000-7,000 lux at 1m on subject (close to limit)
- 300d S: ~8,000-11,000 lux at 1m on subject (comfortable)
300d clearly wins. Large softboxes need more input to produce useful output.
Through 90″ (very large) softbox or through large window diffusion
- 200d S: 2,000-3,000 lux at 1m — may need camera ISO 800-1600
- 300d S: 3,500-5,000 lux at 1m — camera ISO 400-800 manageable
Large-format softbox work is where the 300d’s output advantage matters most.
Use Case Breakdown
Desk-based YouTube creators
200d S is overkill already; 300d S is severely overkill. Subject at 1-1.5m from light, typical softbox, close shooting — 200d S at 30-50% power covers most situations. Don’t buy 300d S for desk-based work.
Full-body studio creators (standing, walking)
Subject at 2-3m from light. Here the 300d’s extra output helps. 200d S still works but at or near full power; 300d S gives breathing room.
Creators mixing with natural window light
If you shoot near a large window, your key light must be brighter than window ambient to dominate the scene. 300d S overcomes typical window light; 200d S can struggle in very bright afternoon sun.
Beauty / product creators with large softboxes
Beauty content often uses 60-90″ octaboxes for ultra-soft output. The 300d S’s extra output is essentially required for this use case — 200d S becomes underpowered with modifiers this large.
Multi-light studio setups
For a key + fill setup, you typically want fill at 50% of key output. Two 200d S can cover most setups with key at 100% and fill at 50%. One 300d S + one 200d S gives you more key output flexibility.
Commercial / client work
For paid client work where production quality is scrutinised, the 300d S’s headroom is worth having. You can always dim; you can’t exceed maximum output.
Total Setup Costs
200d S complete single-light setup (~£475)
- Aputure Amaran 200d S — £329
- 35″ lantern softbox — £80
- Steel light stand — £45
- Grid (optional) — £30
300d S complete single-light setup (~£705)
- Aputure Amaran 300d S — £499
- 60″ octabox with grid — £150
- Heavy-duty steel stand (C-stand recommended) — £80
Key + fill two-light setup
- 2× 200d S: ~£810 (both at high output for flexibility)
- 200d S + 300d S: ~£970 (300d as key, 200d as fill)
- 2× 300d S: ~£1,240 (maximum flexibility, most output)
When the 300d S Is Genuinely Worth It
Specific scenarios where the 300d’s premium is justified:
- Full-body studio with large softbox — 200d S underperforms with 60″+ softbox at typical working distances
- Beauty / product work requiring ultra-soft light — very large diffusion eats output faster than 200d can replenish
- Mixed daylight shooting — studio overlooking bright window needs more output to dominate
- Client/commercial work — output headroom is professional insurance
- Scenes requiring multiple diffusion layers — softbox + inner diffuser + gridded modifier all consume output
When You’re Wasting Money on the 300d S
- Desk-based YouTube with subject at 1-1.5m
- Using medium-size (35-45″) softboxes
- Solo recording with no requirement for output flexibility
- Limited budget where the £170 could go to stands, second light, or other kit
Alternative Lights in the Mid-Range Tier
- Aputure Light Storm 300X (£999) — bi-colour professional tier. 2× premium over 300d S for bi-colour flexibility and premium build.
- Aputure Light Storm 300d II (£799) — daylight pro tier with better construction and broadcast reliability.
- Godox SL-300 II (~£400) — budget 300W COB alternative. Lower CRI, less refined, saves ~£100.
- Nanlite FS-300 (~£450) — mid-range competitor. Comparable but Aputure ecosystem generally preferred.
The 100d S Consideration (Down-Sizing Option)
If you’re weighing 200d vs 300d, also consider whether you should be looking at the Aputure Amaran 100d S (£199) instead.
The 100d S is appropriate for:
- Fill light alongside a 200d or 300d key
- Smaller studio spaces where 200d is excessive
- Budget single-light setups
- Travel/location work (smaller, lighter)
For a two-light setup, 200d key + 100d fill (~£530 + softboxes) is often better than 300d key alone (~£500 + softbox + fill somewhere).
Cooling and Noise Considerations
Both lights use active fans. The 300d runs the fan harder (higher output = more heat). Noise comparison:
- 200d S silent mode: 28dB — inaudible in most recording
- 300d S silent mode: 30dB — slightly audible in quiet environments
- Standard mode (both): 36-40dB — audible but typically below mic pickup threshold
For ASMR-style recording or very quiet scenes, both lights can be audible. The 200d is marginally quieter. For standard creator content, neither noise level is a concern.
Frequently Asked Questions
Is the 300d S’s extra output worth £170?
Depends on use case. For desk-based creators, no. For studio creators using large softboxes or shooting at distance, yes. The 200d S is the default recommendation for most YouTube creators; the 300d S is for specific studio workflows.
Can I get close to 300d brightness by running two 200d lights together?
Sort of. Two 200d lights produce similar total output to one 300d, but positioned from the same angle to simulate one key light source is awkward. For actual dual-source lighting (key + fill), 2× 200d is elegant. For maximum single-key output, 1× 300d is cleaner.
Does the 300d S have significantly better build quality?
Similar build to 200d S. Both use cast aluminium with plastic accents. The 300d is slightly heavier (2.7kg vs 2.2kg) due to larger heatsinks. Neither is Aputure’s Light Storm-tier professional build — for that, look at LS 300d II (£799).
Are these lights powerful enough for daylight exterior shooting?
No. Outdoor daylight (~100,000+ lux ambient) overwhelms both 200d and 300d. For outdoor fill, you need 500W+ (Aputure LS 600d Pro, etc.) or HMI lights. Both 200d and 300d are interior/studio tools.
Can I use both lights on the same power circuit?
Yes. The 300d draws 350W, 200d draws 260W. Two 300d on one UK 13A ring main = 700W, well within capacity. Two 300d + other studio kit should be comfortable on a single domestic circuit.
Do they work with HSS (high-speed sync) for photography?
No — these are continuous LED lights, not strobes. For photography, they work as continuous sources (longer shutter speeds required). For high-speed action photography requiring HSS, you need proper strobes (Godox, Profoto).
How long before LEDs degrade?
Aputure rates 50,000 hours useful life. At 4-6 hours/day of use (typical creator), that’s 25-35 years. The LEDs will outlast other components (fan, power supply, connectors).
Which is better for YouTube thumbnails?
Neither directly — these are continuous video lights. For thumbnails, both work as shooting lights alongside normal camera photography. The 300d’s extra output slightly helps photography (lower ISO possible), but for YouTube thumbnail quality requirements, both are more than adequate.

Both Aputure Amaran COB lights produce excellent broadcast-quality output. The 200d S is the default recommendation — it covers 80% of creator scenarios brilliantly. Step up to the 300d S only when you have specific needs the 200d can’t meet: large softboxes, greater distances, daylight mixing, or commercial work headroom. Don’t buy the 300d for future-proofing — the 200d is genuinely enough for most serious YouTube creators in 2026.
