What Makes a Nail Lamp AI? Camera Recognition, Position Detection and LED Control Explained

The three-part chain

A camera captures the hand. On-device processing identifies nail contours within the frame. A controller then selects which LED zones to activate. Remove any one of the three and the product is a conventional lamp with an interesting shell.

Ask which part runs where. Processing on the device behaves consistently regardless of a network connection; processing elsewhere introduces latency and dependency. For a salon tool, local processing is the sensible choice.

What "detection time" does and does not mean

A published detection time describes how long the system takes to recognise and respond to a hand entering the lamp. It is not a curing time. It is not a measurement of gel cure completion. The two get merged in marketing copy and the result is misleading for buyers.

When you evaluate a lamp, measure the detection behaviour across a range of hand positions — flat, angled, one hand, two hands, someone with darker skin tone, someone with light-reflective adornments. Detection specifications are usually stated under favourable conditions.

Wavelength bands and gel compatibility

A lamp may specify two bands, commonly in the region of 365–370nm and 395–400nm. That describes the emitters. It does not establish that the lamp cures every gel. Photoinitiator systems differ, and a gel that cures well under one configuration may be under-cured under another.

The only meaningful compatibility test is a curing test with the gel products you actually sell, assessed by the method your gel supplier recommends — usually a solvent or abrasion check, not a visual inspection of the surface.

Progressive output and heat

Progressive output ramps energy during the cycle with the aim of managing heat build-up. It is a heat-management approach, and for clients who are sensitive to the exotherm it can make a noticeable difference. It is not a guarantee of pain-free curing, and any copy that says so is overreach.

Evaluate it the way a technician would: on a thick enhancement, with a client who normally complains. That is the scenario where the feature either earns its place or does not.

Maintenance prompts, and why they matter

An LED array can lose output gradually while still appearing to work. A lamp that monitors its own light output and alerts when a threshold is reached gives a salon a reason to check equipment before clients start coming back with service failures.

Note the wording carefully. A maintenance alert is not a measurement of whether gel is fully cured. It is a prompt to service the tool.

Questions to put to any supplier

Where does the processing run? What are the emitter bands and the array configuration? What is the maintenance alert based on, and what threshold triggers it? Which gel systems have been tested, and with what method? What documentation is available for my market?

A supplier who can answer these without hedging is a supplier worth sampling. A supplier who answers with adjectives is not.

A camera, a processor and a zone controller. Everything else in the AI nail lamp conversation is marketing until you can point at those three.
