Lightdot 2FT High Bay 8-Pack With Driver
This 8-pack 2-foot linear high bay fixture delivers up to 28,000 lumens at 5000K, using SMD2835 LEDs with up to 140 lm/W efficacy. It replaces traditional 800-watt MH or 6-lamp T8 high bays while offering significant energy savings—up to 80% under typical usage. The heavy-duty steel housing provides robust heat dissipation, and the driver is designed for long life (50,000+ hours). The 2×2 footprint helps eliminate dark zones and ensures uniform illumination across large spaces like warehouses, manufacturing floors, and garages. The kit includes a milky diffuser to minimize glare and soften the daylight white output.
Lightdot 2FT High Bay 4-Pack With Driver
This 4-pack option mirrors the 8-pack’s core performance: 28,000 lumens from 200W, 5000K daylight, and an ETL-listed build. Its sturdy steel housing provides reliable heat management for demanding environments like warehouses and workshops. The design emphasizes a large luminous area with a non-flicker LED driver, making it suitable for long shifts and precision tasks. It’s a practical choice for facilities expanding lighting coverage without committing to a larger initial order.
Lightdot 2FT High Bay 8-Pack Diamond Diffusion
This model emphasizes Diamond Diffusion and a premium diffuser to minimize yellowing and glare, while delivering consistent 28,000 lumens at 5000K. The rugged black steel housing supports robust heat dissipation and long service life. The design aims to keep output stable for more than 50,000 hours, making it suitable for busy facilities that require dependable, flicker-free lighting across large work zones. External sensor compatibility is an added convenience for automation-ready spaces.
Lightdot 2FT High Bay 4-Pack Diamond Diffusion
This 4-pack brings the benefits of the Diamond Diffusion design to a compact purchase. The 200W LED fixtures deliver 28,000 lumens with a 5000K color temperature and 90 CRI for true color rendering. The fixtures use a black steel housing with high heat dissipation, ensuring reliable performance in large spaces. The diffuser helps maintain a soft, uniform light that reduces eye strain during long shifts and supports critical tasks in warehouses and shops.
Lightdot 2FT High Bay 8-Pack Flush/Suspended Mount
This model emphasizes installation versatility with flush or suspended mounting options. It provides a 120-degree beam angle and 28,000 lumens at 5000K, covering up to two thousand square feet per unit in warehouses with 15- to 30-foot ceilings. The heavy-duty steel housing includes aviation-grade heat sinks for rapid dissipation, and the fixture is designed to operate for tens of thousands of hours, minimizing maintenance needs for large facilities.
Buying Guide: Key Considerations For 2×2 High Bay LED Lights
- Light output and efficiency: Look for fixtures offering at least 28,000 lumens with 140 lm/W or higher efficacy to ensure bright, even coverage in tall spaces. Higher efficiency reduces energy costs while maintaining brightness.
- Color temperature and CRI: A 5000K daylight tone is common for industrial spaces and provides good contrast for accuracy in tasks. A CRI of 90 ensures true color rendering, which helps in spotting subtle differences in materials and products.
- Beam angle and footprint: A wide beam angle (around 120 degrees) and a 2×2 footprint minimize dark zones. The 2×2 design is specifically meant to cover large, open interiors with fewer fixtures.
- Driver quality and lifespan: Choose fixtures with non-flicker, long-life drivers (50,000+ hours). A driver that operates reliably reduces maintenance and improves visual comfort.
- Durability and heat management: Industrial steel housings and effective heat sinks help maintain performance in heat-prone environments like warehouses and mechanical rooms.
- Mounting flexibility: Options for flush, suspended, or hanging installations expand where these lights can be used, including high ceilings and retrofits.
- Voltage compatibility: Most options support 100-277V, allowing easy integration with existing electrical infrastructure and minimizing the need for additional transformers.
- Maintenance and service life: Consider fixtures with long rated lifespans and clear warranty coverage. This reduces replacement frequency and total cost of ownership.
- Sensor integration: Some models offer photocell or motion sensor compatibility, enabling energy-saving automatic control aligned with space usage.
- Warranty and support: A robust 5-year warranty and access to technical support help ensure reliability over the life of the installation.
Industrial spaces benefit from standardized, high-quality LED high bays that deliver consistent lighting, reduce energy bills, and minimize maintenance. The Lightdot 2×2 family described above provides multiple purchasing options—whether you need bulk setups, varied mounting, or diffusion-focused designs—to match different ceiling heights, work processes, and space layouts. When evaluating choices, prioritize lumen output per watt, diffuser quality, and installation flexibility to achieve uniform illumination and long-term performance.
