GerTong 11.5 inch ring, 40 RGB colours, over 150 settings review
An 11.5 inch ring that publishes its diameter twice over in centimetres, with 40 colours, 37 dynamic modes and over 150 settings for 30 € — and not one figure in kelvin.
The bottom line Two published diameters in centimetres, 40 colours, a weighted folding stand and a mini tripod for 30 € — the hardware is well described and the colour work is the most extensive here. White light is named in words rather than kelvin, no index is given, and neither stand height appears.
On the listing
Five bullets. Bright LED beads with a long life, UV-free, flicker-free, no ghosting and no glare, behind a curved cover that softens and widens the light, with an outer diameter of 29.2 cm and a maximum vertical dimension of 30.48 cm including the part below the ring; more than 150 settings and 40 RGB colours — three daylight modes named white, warm white and warm yellow, seven RGB colours, 13 brightness levels per mode from 1 to 100 per cent, and 37 dynamic RGB modes; a wide phone clip from 2.2 to 3.4 inches on a flexible gooseneck with adjustable ball joints; a folding stand with quick catches and a weighted base plus a mini desktop tripod, usable as a desk or make-up light; and a remote release paired through AB Shutter3, with USB power from most devices with a USB port.
Twenty-nine point two centimetres, measured twice
The only page on this shelf that says how much desk it needs. An inch figure describes the ring; 29.2 cm across and 30.48 cm tall including the mount describes the object. For anyone fitting a light between a monitor and a wall, the second pair is the useful one.
A hundred and fifty settings, and not one index
Three whites, seven colours, thirty-seven animations, thirteen brightness steps each. It is the most versatile page here for making a background interesting, and there is no figure anywhere for how faithfully any of it renders a face.
The gooseneck and the mini tripod
Two pieces of hardware that change how the light is used: a bendable arm so the phone sits where the shot wants it rather than where the ring is, and a small tripod so the whole thing becomes a desk lamp. Both are supplied, and neither stand has a published height.
Flicker-free, without a frame rate
The claim is in the first bullet and nothing qualifies it. Steady at one frame rate is not steady at all of them, and the page names none.
Availability
Between 30 € and 36 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.
The British Amazon store carry it too, priced in local currency. Those amounts are deliberately absent from the range above, which reads euro stores only.
Nothing came back from the American Amazon store at all, so the button for that country runs a search instead of opening an entry that is not there.
Everything in this section is the figure Keepa carried on the day of the last update to this page. Availability and prices shift without notice.

What it does well, and what it gives up
Strengths
The outer diameter published in centimetres, 29.2 cm, and again as 30.48 cm including the mount below the ring
Forty colours and 37 dynamic modes, with 13 brightness levels each from 1 to 100 per cent
A folding stand with a weighted base and a mini desktop tripod, both supplied
Compromises
No kelvin figures at all, on a page that measures the ring to a hundredth of a centimetre
No colour accuracy index, and no stand heights published
The remote needs a named third-party app, AB Shutter3, to pair
Specifications
Diameter
11.5 inches, and the first bullet then does something no other page here does: it gives 29.2 cm as the outer diameter and 30.48 cm as the maximum vertical dimension including the part below the light ring. Two measurements, so the space it will occupy on a desk is known exactly rather than estimated from an inch figure
Colour temperature range
Not published in kelvin. The second bullet names three daylight modes — white, warm white and warm yellow — alongside seven RGB colours, and no figures appear at either end. It is the most colourful page on this shelf and the least precise about white light
Colour accuracy
Not published. The first bullet claims UV-free, flicker-free light with no ghosting and no glare, which is a set of absences rather than an index. Over 150 settings are advertised and none of them is a measurement
Mounting method
Stand-mounted, two ways: the folding stand with a weighted base, or the supplied mini desktop tripod, which the fourth bullet says lets it serve as a desk lamp or a make-up light. No clip and no camera thread is named
Stand supplied
Yes — a folding stand with quick-release catches and a weighted base for stability, plus a separate mini desktop tripod. No heights are published for either, which is the notable gap on a page that measures its ring in two directions
Power
USB, in the fifth bullet, working with most devices that provide a USB port — a charger, a power bank, a computer or a mains adapter. No current recommendation is given, unlike the ring below it which warns that a weak supply dims the light
Holder provision
A phone clip extending from 2.2 to 3.4 inches on a flexible gooseneck that can be turned and bent to any angle, with several adjustable ball joints. A remote release is included and the fifth bullet names the app it pairs through, AB Shutter3. No camera thread is named

What people ask before they commit
What are the 37 dynamic modes for?
They are animated colour sequences — the second bullet names cyclic, progressive and fast flashing — used as background interest or atmosphere in video rather than as light on a face. With seven RGB colours and three whites they add up to the 150-plus settings the bullet advertises. They are presets, not specifications, and no colour figure stands behind any of them.
Why is publishing 29.2 cm useful when the title says 11.5 inches?
Because a desk is measured in centimetres and an inch figure is a marketing size. The bullet gives both the outer diameter and the 30.48 cm total including what hangs below the ring, so whether it will fit between a monitor and a wall is a question that can be answered before buying. No other page on this shelf does this.
Is flicker-free a meaningful claim here?
It is a claim without a condition. Flicker matters at specific frame rates and shutter speeds, and a light that is steady at 25 frames per second may band at 120. The hub above lists flicker among the things to check beyond the numbers; this page asserts the absence and names no frame rate, so it cannot be verified from the listing.

A 10 inch ring whose stand reaches 182 cm overall — the tallest on this shelf — with a geared head that holds its angle, for 32 €, and no power source stated anywhere.
Best for: Standing or seated full-length video where the light has to reach head height, and the head must stay at the angle it was set to.
18 inch, 45 cm outer diameter · 55 W · fixed 5600K · 240 LEDs · dimmable 0 to 100 per cent · no colour accuracy index · 155 cm aluminium-alloy light stand · colour filter set supplied instead of bi-colour mixing · soft tube, ball head and hot shoe adapter for cameras · phone holder · universal mains adapter · carry bag · no UV or IR emission claimed
The largest and dearest ring here — 18 inches, 45 cm, 55 W of daylight from 240 LEDs — with a camera shoe adapter, colour filters and a 155 cm stand, at 107 €.
Best for: Portrait, beauty and salon work at a proper distance, where 45 cm of daylight-balanced source and a camera mount are the reasons to buy.
6 inch ring · three lighting modes, cold, natural and warm, with no kelvin figures · 10 brightness levels · no colour accuracy index · weighted metal base with foam padding · telescopic tube from 17.7 to 24 inches · 360 degree swivel head · phone holder for 2.36 to 3.54 inch devices · universal clip up to 15 mm for laptops and monitors · storage bag · no power source published
The smallest and cheapest ring here at 15 €, with a weighted desk base and a clip that grips a monitor up to 15 mm — three colour modes named in words, and no kelvin figure anywhere.
Best for: A desk or a laptop for calls and close work, where the clip and the weighted base matter more than the size of the source.
