# 24-month warranty and lamp care

Frame and shade are covered for 24 months; bulbs and cable follow the manufacturer's warranty. Most of the care is a monthly dusting and hanging the lamp in a dry room.

Updated 4 Oct 2026

## What the warranty covers

**The brass frame and the shade are covered for 24 months** from installation, tracked by the number under the canopy and its line in our ledger. A bent frame or opened joint, strands coming loose on a shade, a peeling coating, a loose socket caused by our workmanship: we repair or remake it free of charge.

**Bulbs and cable** are covered by their manufacturers. If one fails, fit the spare from the box.

**Not covered:** raw brass darkening, shades damaged by hanging in a bathroom, on a porch or in a damp room, shades cleaned with water, and lamps taken apart or repaired by someone outside the workshop.

## Rattan and seagrass

Dust once a month with a dry cloth or soft brush. No sprays, no damp cloths. The matte moisture coat slows down how much damp the fibre takes up; it does not make it waterproof. If spots appear, send us a photo before you try anything yourself. More on the [rattan page](/en/materials/rattan) and in our note on [rattan in the rainy season](/en/journal/rattan-lamps-humidity-care).

## Dó paper

Dó paper (giấy dó, made from the bark of the dó tree) is strong, but keeping it dry is the whole job. A soft feather duster only, no damp cloths, no oily fingers. Hang it in an air-conditioned room, never in a bathroom or kitchen or a closed-up room in the rainy season. See the [dó paper page](/en/materials/do-paper).

## Raw brass

Raw brass has no lacquer and darkens over the years. Dust it with a soft dry cloth. Skip polish and cleaners: polish one spot and it turns into a bright patch against the rest. Matte black and white frames just need a dry cloth. See the [brass page](/en/materials/brass).

## Replacing an E27 bulb

Every lamp takes an E27 bulb, the standard screw fitting sold everywhere in Vietnam.

1. Switch off and give the bulb a few minutes to cool.
2. Steady the shade with one hand and unscrew the bulb anticlockwise with the other.
3. Fit an LED bulb marked E27, 2700K, 6 W.

LED only. Never put an incandescent or high-wattage bulb inside a rattan, seagrass or paper shade. For dimming, the bulb must be marked dimmable and paired with a wall dimmer.

## When a lamp fails

Call 0900 000 002 or message us on Zalo, Tuesday to Sunday, 9:00 to 18:00\. Tô Minh Khang answers. Have ready:

- The number under the canopy.
- A photo or short video of the problem.
- What is wrong: no light, flickering, buzzing, or a problem with the shade or frame.

Try a different bulb first; most lamps that stay dark just have a dead bulb. If it still fails, Khang books a visit for orders in Ho Chi Minh City, or explains how to send the lamp back for orders in other provinces. Other questions are on the [FAQ](/en/faq) and [contact](/en/contact) pages.

## Not sure which lamp?

Send one photo of the room. Within 48 hours you get it back with the lamp drawn in, free.
