On the makers' own published output and prices, the $69 amaran Ace 25x delivers a lux for 1.1 cents, against 12.3 cents for the $29 amaran Go. Read on 26 October 2026.
Lattice finding
On the makers' published full-power output at 0.5 m and US prices, the $69 amaran Ace 25x delivers a lux for 1.1 cents, against 1.7 for the Ace 25c, 2.2 for the Ulanzi C10 and 12.3 for the $29 amaran Go, so the $29 amaran Go costs more than 11 times as much per lux as the $69 Ace 25x.

Listed at 6,320 lux at 0.5 m, 32 W maximum power, 2,700K to 6,500K and about 70 minutes of runtime on amaran's comparison table: 1.1 cents per lux, the lowest of the lights priced here.
CRI 95+ and TLCI 95+, 2,300K to 10,000K, a 50 degree beam, 5,908 lux at 0.5 m, a 4,500mAh / 33.3Wh battery and a 325.5 g body. Runtime is about 50 minutes in Boost, 70 in Standard and 4 hours 40 in Silent.
112 LEDs and 1,000 lumens, CRI above 96, 2700K to 7500K, an aluminum shell 0.39 inches thin, and a battery that runs about 90 minutes at maximum and up to 16 hours at the lowest output.
A 10 W RGB pocket light with a 120 degree beam, about 1,120 lux at 0.5 m, CRI of 93 or more, a magnetic diffuser and Type-C charging; about 120 g without the diffuser.
Listed at 235 lux at 0.5 m and 2,700K to 6,500K with a charge time of about 70 minutes: the lowest output of the lights priced here, and the highest cost per lux.
Four published numbers decide a pocket light: output (lux at a stated distance), colour rendering (CRI or TLCI), colour temperature range, and runtime at a stated power level. CRI and TLCI are the makers' own colour-rendering scores: amaran lists CRI 95+ and TLCI 95+ for the Ace 25c, Lume Cube lists CRI above 96 for the Panel Go, and Ulanzi lists CRI of 93 or more for the C10.
Output is quoted at 0.5 m, a close distance, and it falls fast with distance: light spreads out, so doubling the distance cuts the lux to a quarter. Runtime is quoted at a power level, usually full output, so the number on the box is the worst case.
The five lights span $24.99 to $99 and 235 to 6,320 lux at 0.5 m. Cost per lux, from published output, is lowest on the amaran Ace 25x and highest on the amaran Go.

Makers' own pages, read 26 October 2026. "Not on the page read" means we did not find the figure on that page, not that the maker does not publish it. Neewer RGB1, Lume Cube Panel Mini, Ulanzi PL25, Godox and SmallRig lights are not priced here: our fetcher was rate limited on the Neewer, Lume Cube Panel Mini and Ulanzi PL25 pages on 26 October 2026, Godox's LITEMONS page shows no prices, and SmallRig's RM75 page had been removed on our 14 October read.
Put the light close, slightly to one side, and aim it at the face; the three plans below show the throw distance, the field it lights and the estimated lux at the face for each shooting environment. Close matters most: at 0.5 m the Ace 25c delivers 5,908 lux, but at 1.0 m it is an estimated 1,477, a quarter as much.
The C10's wide 120 degree beam covers a 2.4 m field at 0.7 m, so it lights the face and the wall behind from the side opposite the window. Estimated 571 lux at the face.
The Ace 25c's 50 degree beam is a 0.58 m spot at arm's length: a face-sized field with about 3,842 lux and 50 minutes at Boost, 70 at Standard.
With the sun behind the subject the face is in shade; the Ace 25c at 1 m adds about 1,477 lux over a 0.93 m field. A reflector costs no battery, but only bounces light that already exists.
INDOOR DESK (mixed window and room light) SETTING: daylight colour temperature to match the window; lowest output that lights the face PLACE: 0.7 m from the face, about 40 degrees off the camera axis, on the side away from the window CHECK: 2.4 m field at 0.7 m for a 120 degree beam; about 571 lux at the face (Ulanzi C10 figures) NIGHT STREET (handheld) SETTING: full output only for the shot, then drop it: runtime is 50 min at Boost, 70 min at Standard PLACE: on the rig about 0.6 m from the face, slightly off the lens axis CHECK: a 50 degree beam is a 0.58 m field at 0.62 m; about 3,842 lux (amaran Ace 25c figures) OUTDOOR FILL (sun behind the subject) SETTING: the light fills shade; a reflector is the no-battery alternative PLACE: 1.0 m from the face, about 35 degrees off the camera axis CHECK: about 1,477 lux at 1.0 m (amaran Ace 25c figures) TRAVEL [ ] Each battery under 100 Wh (the Ace 25c is 33.3 Wh); spare batteries in carry-on only (FAA PackSafe)
A reflector is the alternative outdoors: it adds no light of its own, only redirects what is already there, so with the sun behind you it fills the face for free, and a battery light is what you reach for when there is nothing to bounce. Indoors, the plan keeps the light on the side away from the window so it fills shadows instead of fighting the window's direction.
Battery life depends heavily on the power level: the Lume Cube Panel Go runs 90 minutes at maximum and up to 16 hours at its lowest output, the Ulanzi C10 about 55 minutes at 100% and 110 minutes at 50%, and the amaran Ace 25c 50 minutes at Boost against 280 minutes in Silent mode. Plan a shoot around the output you need at the face, not the headline runtime.
Yes for batteries this size: the FAA says lithium ion batteries are limited to 100 watt hours per battery, and that spare lithium batteries, including power banks, must be carried in the cabin, not checked baggage. The amaran Ace 25c's 33.3 Wh battery is one third of the limit, and the Ulanzi C10's 3300mAh at 3.7V works out to about 12.21 Wh. For anything bigger, FAA PackSafe allows up to two spare batteries of 101 to 160 Wh with airline approval; FAA PackSafe and TSA's page on batteries over 100 Wh give the rule in full. Your airline can be stricter.
We compared five portable lights on the output, beam angle, colour-rendering scores, colour temperature range, battery and runtime figures and US list prices each maker publishes on its own pages (amarancreators.com, lumecube.com and ulanzi.com), read on 26 October 2026, and on the FAA's PackSafe lithium battery rules. The cost-per-lux finding is computed from price and published lux at 0.5 m. Lux at the face in the plans is an inverse-square estimate from those published figures, not a measurement, and the throw distances are stated assumptions. We did not shoot with these lights for this guide, so nothing here is a handling or image-quality claim.

It depends on where you shoot. On the makers' published figures read on 26 October 2026, the Ulanzi C10 ($24.99, 120 degree beam) suits a desk, the amaran Ace 25c ($99, 50 degree beam, CRI 95+) suits handheld night shooting, and the amaran Ace 25x ($69) is the cheapest per lux.
Makers quote lux at 0.5 m at full output: 235 for the amaran Go, 1,120 for the Ulanzi C10, 5,908 for the amaran Ace 25c and 6,320 for the Ace 25x. Lume Cube states 1,000 lumens for the Panel Go. Lux falls to a quarter at double the distance.
It depends on the power level: the amaran Ace 25c runs about 50 minutes at Boost and 280 minutes in Silent mode, the Ulanzi C10 about 55 minutes at 100% and 480 minutes at minimum, and the Lume Cube Panel Go 90 minutes at maximum and up to 16 hours at lowest output.
Generally yes: the FAA limits lithium ion batteries to 100 watt hours per battery and requires spare batteries to travel in the cabin, not checked baggage. The amaran Ace 25c's battery is 33.3 Wh. Larger batteries of 101 to 160 Wh need airline approval, and airlines can be stricter.
Only when the face is in shade. A reflector bounces existing light at no battery cost; a light adds its own. In the outdoor plan the amaran Ace 25c at about 1 m adds an estimated 1,477 lux over a 0.93 m field.
CRI is a colour-rendering score the maker publishes; higher means colours look closer to natural light. amaran lists CRI 95+ and TLCI 95+ for the Ace 25c, Lume Cube lists above 96 for the Panel Go, and Ulanzi lists 93 or more for the C10.
Match the light to where you shoot and put it close: a wide, cheap light such as the Ulanzi C10 at a desk, a narrow, bright one such as the amaran Ace 25c on a handheld night rig, and a reflector first outdoors. On published figures the amaran Ace 25x is the best value per lux at 1.1 cents, and every light here travels in a carry-on under the FAA's 100 Wh battery limit.
