Barrina Orbgrow OG11A Grow Light Bulbs – 2-Pack, 5000K Full Spectrum, E26, Dimming & Timer

Smart lighting for compact indoor gardens

The Barrina Orbgrow OG11A bulbs bring a bright, steady glow to small spaces. This 2-pack delivers a combined 22W of efficient LED light (two 11W bulbs) with a 200W equivalent feel, rendered in a clean 5000K daylight that helps plants keep a vibrant, green appearance from seed to green harvest. With integrated controls and a streamlined design, you can set up a tidy, capable lighting solution without extra accessories.

Beyond mere brightness, these bulbs are built to support diverse indoor setups—from shelf gardens to grow tents and tabletop plots. The result is a reliable, uniform light source that stays with you as plants transition from seedlings to leafy greens. Real-world use often reveals a consistent, calm glow that keeps you in control of your growing environment while minimizing clutter.

Smart controls you’ll actually use

• Integrated stepless dimming directly on the bulb for precise brightness without extra hardware.
• Three timer settings (4/8/12 hours) to fit your daily schedule and plant needs.
• No extra accessories required—plug in and start growing with standard fixtures.

What makes OG11A stand out

• E26 base compatibility, making it easy to swap into most fixtures and create instant lighting in tight spaces.
• High output: 1550 lumens with a strong PPFD of 1980.5 μmol/m²/s at a 10 cm canopy height, supported by 36 efficient chips.
• Full spectrum with a CRI of 98, designed to cover the wavelengths plants use across growth stages, from seedlings to leafy greens.
• 5000K color temperature delivers a daylight-like glow that helps plants maintain a steady, natural appearance.
• Efficient heat dissipation using a plastic/aluminum cooling design to keep canopy temperatures in a plant-friendly range.
• Minimum distance guidance of about 7.87 inches (20 cm) above the canopy to maximize growth while reducing overheating risk.
• 2-pack convenience is ideal for supporting multiple plants or paired installations in a compact setup.

Real-world scenarios and setup ideas

Perfect for seedling trays, herb shelves, compact microgreens setups, and small grow tents. The integrated dimming and timing let you tailor light to the plant’s stage, while the E26 base keeps installation quick and simple on existing fixtures. For larger or multi-plant spaces, pair OG11A bulbs with other Barrina units to build a broader, blended lighting plan.

Notes on expectations

While the OG11A offers strong, full-spectrum light with adjustable brightness and scheduling, results can vary based on other growing factors such as temperature, humidity, and plant type. Consider these bulbs as a versatile lighting option that may help support healthy growth when used in a well-managed environment.
