Never use incandescent or halogen bulbs in this fixture. The rice-paper shade and bamboo ribs are flammable and cannot safely absorb the heat of a traditional bulb. Both shapes ship with a 5W warm-white LED bulb; replacements should also be LED only, at or below 7W. If the bulb feels warm to the touch in normal use, switch to a lower-wattage LED. Always switch off and let the bulb cool before changing it.
Unpack carefully — the paper shade is fragile and can tear or dent if knocked against the box edge. Lift the lantern by the wire handle or by the bottom ring, never by the paper.
