Barrina Orbgrow OG11A Grow Light Bulbs – 4000K Full Spectrum, E26, 4-Pack with Dimming & Timer

Smart, space-saving grow light for indoor plants

Meet Barrina Orbgrow OG11A, a four-bulb grow light system designed to fit standard fixtures and crowded urban growing spaces. The standout feature is an integrated dimming and timer panel on the bulb itself, letting you dictate brightness with smooth, stepless control and set 4/8/12 hour cycles without extra accessories. This focus on simplicity helps you keep your grow space clutter-free while delivering consistent light across your plant collection.

With a 4000K daylight tone, the bulbs emit a natural, unintrusive glow that complements home décor while providing plant-appropriate energy. The full spectrum covers the range your plants rely on, from seedling vigor through vegetative growth to budding greens, and the CRI 98 rating helps you perceive healthier foliage and true color notes as you monitor progress.

Technical performance matters too. Each OG11A bulb delivers about 1460 lumens and a robust PPFD of 1497.3 μmol/m²/s when positioned roughly 3.94 inches (10 cm) above the canopy. The 36 high-efficiency chips are arranged to provide a broad, even field across compact shelves or tents, so you can build layered lighting without hot spots or purple tint.
