The Day Birch mushroom table lamp is shaped from iron into a sleek mushroom form that reads as a sculptural object on a desk, a bedside table, or a bookshelf, standing 15" (38cm) tall and 9.8" (25cm) wide. Three lighting colours (warm white, natural white, and cool white) pair with dimmable brightness so the output adjusts from a focused working level to a softer ambient glow without changing the fixture. The LED light source keeps energy consumption low across all three colour temperatures and the full dimming range.

The USB rechargeable design powers the lamp for 5 to 6 hours per charge, covering a full work session or an evening of ambient use without needing to stay tethered to a cable. Gold, Black, and White colour options sit across the same iron mushroom form, each finish giving the lamp a different surface character while keeping the same proportions and the same three-colour dimmable output. The iron construction keeps the lamp stable on any surface without additional anchoring, and the intuitive controls make brightness adjustments straightforward from first use.
