1. Singapore Plug and Voltage — What You Need to Know

Singapore uses the Type G plug (3-pin, UK-style) at 230V / 50Hz. The United States uses 110V / 60Hz with a Type A/B plug. These are fundamentally different electrical specifications.

Celluma devices use a switch-mode power supply (100–240V auto-switching), which means the internal electronics can technically operate in both markets. This is why many electronics bought overseas work in Singapore. However, this voltage compatibility is only part of the picture for a medical-grade device.

The practical implication: a US plug Celluma with an adapter will power on in Singapore, but the device will have a US warranty (which does not cover Singapore use), no local support structure, and no protection against local electrical events. The Celluma Surge Protector is recommended for any Import Set unit used locally.

2. Local Set vs Import Set — The Full Comparison

Celluma Asia offers two purchasing options for every device: the Local Set and the Import Set. Here is the exact difference across every relevant dimension.

3. What the Warranty Actually Covers

This is where the two sets differ most meaningfully — and where the Local Set's value becomes clearest. With a medical device you use daily, the question isn't if something might go wrong over two years. It's what happens when it does.

Import Set — US Manufacturer's Warranty

Covers manufacturer defects for the standard US warranty period. Claims are supported locally by Celluma Asia. Servicing is repair-based — components are fixed, not replaced. The US warranty does not formally extend to devices used outside the US, but Celluma Asia facilitates the claims process as the authorized regional distributor.

Local Set — 2-Year Full-Unit Replacement Warranty

Full-unit replacement warranties are genuinely rare in the medical device industry. Most manufacturers offer repair-based coverage because replacement is significantly more expensive. Celluma Asia's Local Set offers it because we believe it is the only appropriate standard for high-precision clinical equipment.

The reason is straightforward: LED modules are the most critical components in a photobiomodulation device. Wavelength accuracy, irradiance output, and LED driver calibration are factory-set parameters. Once a device is opened for service, original integrity can be compromised — even by skilled technicians. A repaired panel introduces uncertainty that should never exist in a device where clinical outcomes depend on hitting exactly 640nm at a precisely calibrated fluence.

Full-unit replacement removes this uncertainty entirely. If the LED panel or controller fails — even from a single non-functioning LED — you receive a brand-new factory unit. Not repaired. Not recalibrated. Factory-fresh, with every parameter identical to the device you first used.

4. Local Support and After-Sales Service

Both sets are backed by Celluma Asia's local team. This matters beyond just warranty — it covers how you use the device from day one.

This is the practical reason to buy locally rather than directly from the US or via a grey market reseller. A device bought through an unauthorized channel arrives with no regional support, no warranty infrastructure, and no specialist available when you have questions about protocols or performance.
