Ammonite System vs Cressi
LED ONE MINI vs Astra 2100 Dive Torch
Controls, charging and beam choice for your next torch.
Cressi
Scores are our editorial opinion of these models, based on features, suitability and ownership trade-offs—not hands-on test results. How we chose →
We’d pick the LED ONE MINI.
We’d start with Ammonite System LED ONE MINI. We like the compact narrow-beam approach when CR123A cells fit your spare-battery plan. Choose Cressi Astra 2100 Dive Torch instead if its strengths are a better match: astra appeals to us for magnetic charging and simple full- or half-power selection without opening the body.
Which one suits you?

We like the compact narrow-beam approach when CR123A cells fit your spare-battery plan. Choose the full-size LED ONE if AA availability matters more to you.

Astra appeals to us for magnetic charging and simple full- or half-power selection without opening the body. The battery is built in, so it is a different travel and charging choice from a torch with swappable cells.

What the differences mean when you buy
Beam and usable illumination
Ammonite System LED ONE MINI
- Beam
- 6°
- Output
- 400 lumens, current model
Cressi Astra 2100 Dive Torch
- Output
- 2100 lumens
Compare beam angles measured on the same basis. An explicitly underwater angle is not automatically comparable with an unlabeled angle, and total lumens do not measure central intensity on the subject. Adjustable beams change coverage. Watts describe electrical power and cannot be directly ranked against another light’s lumen figure.
Battery and output over time
Ammonite System LED ONE MINI
- Battery
- Two CR123A cells
- Rated runtime
- About 5.5 hours
Cressi Astra 2100 Dive Torch
- Battery
- Built-in 5000 mAh
- Charging
- Magnetic USB
Distinguish constant full output from a period that includes reduced output. Up-to runtime and runtime at a selected power level are different claims. Confirm the supplied battery, approved chemistry, charging arrangement and available spares. A matched endurance winner requires comparable conditions rather than simply selecting the larger printed number.
Handling, mounting and package
Ammonite System LED ONE MINI
Ask the brand about this detail before ordering.
Cressi Astra 2100 Dive Torch
Ask the brand about this detail before ordering.
Try the controls with gloves and evaluate the complete mounting arrangement. A ready-to-use weight including a handle is not equivalent to a bare light-head measurement. Check lanyards, mounts, chargers and cells in the package, and establish the light’s role within your planned lighting system rather than selecting it on a depth-rating headline.
A closer look at both
LED ONE MINI
The current LED ONE MINI is a 400-lumen backup torch using two CR123A batteries. Its 6° beam concentrates the light into a small area, and the twist-operated aluminium head sits on a Delrin body. Ammonite quotes about 5.5 hours of operation and a 200 m depth rating.
What we like
We like the compact narrow-beam approach when CR123A cells fit your spare-battery plan.
What would make us think twice
Choose the full-size LED ONE if AA availability matters more to you.
More about the LED ONE MINI →Astra 2100 Dive Torch
The Astra 2100 is Cressi’s rechargeable scuba torch with full, half and strobe settings. A magnetic USB connector charges its built-in 5000 mAh battery without opening the housing. The current store description specifies a CREE XHP50 LED and a maximum output of 2100 lumens.

More about the Astra 2100 Dive Torch →Four checks before you place an order
- Identify the intended lighting role and the beam coverage it requires.
- Compare current revision, output mode and runtime basis using the exact manufacturer specification.
- Try controls and mounting with your normal gloves and equipment.
- Confirm supplied batteries, chargers, approved spare cells and transport guidance for the trip.
Ask for a quote for the complete kit, including the accessories you need. That makes the price comparison much more useful.
Price, accessories and owning the equipment
Include the battery, charger, spare pack and mounting arrangement in the purchase total. A light supplied without cells or a proprietary pack can have different ownership costs from an apparently similar complete kit. Ask about replacement O-rings, charging parts and service support rather than judging value by lumen count alone.
For an upgrade, identify whether the current issue is beam shape, control access, reliable output duration or handling. Follow the manufacturer guidance for battery handling, sealing and charging. A cave or technical model name is not an endorsement for an overhead dive or a substitute for the required lighting plan and training.
How we scored these models & further reading
These are our subjective buying scores out of 100. We weigh the usefulness of the features, the intended diving or carrying job, and the compromises involved in owning the gear. They are not laboratory measurements, safety grades or customer averages. The verdict applies to the two named models, not everything either brand makes.
90–100: one of our first choices for the stated job. 80–89: a strong option with trade-offs. 70–79: a more specific fit. A different fit, camera, valve or dive plan can change which one you should buy.

Questions worth settling
Does the higher lumen number mean the better dive light?
Not by itself. Beam geometry, output duration, controls and the intended role matter. Published figures may use different measurement conditions. This comparison does not create a performance score where there is no matched independent test.
Which is the better buy for this particular comparison?
Ammonite System LED ONE MINI: Choose the full-size LED ONE if AA availability matters more to you. Cressi Astra 2100 Dive Torch: The battery is built in, so it is a different travel and charging choice from a torch with swappable cells.
Our pick is where we would start. Choose the other model if its fit or features better match your setup—especially where a camera, valve, boot or exposure suit needs an exact match.
