plant lamp

Many grow lamps advertise full-spectrum output (noted around 380–780 nm) and offer specific color temperatures such as 3500K, 4000K, and 6400K depending on the model.

Control options include built-in cycle timers (common presets like 4/8/12 hours) and digital 24-hour timers with minute-level scheduling. Dimming ranges from simple step dimming to multi-level or 10-level brightness control, using dedicated dimmer knobs, switches, or electronic controls.

Adjustability varies by model: some stands offer multi-level height settings up to about 75 inches and rotatable lamp heads; smaller plug-in stems extend roughly 8–28 inches. Flexible goosenecks and 360° head rotation are also commonly used for precise aiming.

Lumen outputs range from a few hundred to several thousand. Example listings show values such as 250, 900, 1,464.99 and 5,150 lumens. Color-rendering (CRI) values in listings range from about 50 up to 98+ depending on the fixture.

Listings include standard AC-powered fixtures with US or 120V plugs, USB-powered lamps, and plug-in units designed for direct wall or corded power.

Common features include aluminum bodies or COB aerospace-grade aluminum for improved heat dissipation, self-cooling technologies, unibody heatsinks, and durable housings designed to reduce output degradation and protect against dust and humidity.
