TotalGrow™ Deep Red Specialty Light Bar – 24in 25W 660nm Supplemental Grow Light

The TotalGrow™ Deep Red Specialty Light Bar is a 24-inch, 25-watt supplemental horticultural light designed to deliver targeted 660nm deep red light to indoor growing facilities, greenhouses, and other controlled-environment agriculture systems. The deep red spectrum supports photosynthetic activity and plant growth when used alongside compatible primary grow lighting.

Producing 65 µmol/s of photon output at an efficacy of 2.6 µmol/J, the TotalGrow Deep Red Specialty Light Bar provides an energy-efficient way to increase targeted red-spectrum intensity without replacing an existing grow lighting system. Its 660nm output can help improve spectral balance and provide additional photosynthetically useful light for plant development.

The fixture's slim 23.7-inch linear profile allows it to integrate easily into greenhouse structures, indoor grow rooms, vertical farming racks, and existing horticultural lighting layouts. Its modular design also supports daisy-chain linking of multiple fixtures, making it easy to expand supplemental deep red lighting across larger cultivation areas.

Designed for demanding growing environments, the TotalGrow Deep Red Specialty Light Bar features an IP65 rating, ETL certification, projected 30,000-hour service life, and 3-year warranty. A 120V power cord and two suspension hangers are included for convenient installation.

What Is the TotalGrow Deep Red Specialty Light Bar Used For?

The TotalGrow Deep Red Specialty Light Bar provides concentrated 660nm deep red light as a supplement to a primary horticultural lighting system. Deep red wavelengths fall within the photosynthetically active range used by plants and can be incorporated into lighting strategies designed to support photosynthesis, growth, and overall plant development.

Rather than functioning as a standalone grow light, this fixture is designed to complement existing lighting. Growers can use it to add targeted deep red intensity, adjust spectral balance, and provide additional photosynthetically useful light in areas where the primary fixture's spectrum or intensity may benefit from supplementation.

Why Use 660nm Deep Red Light for Plants?

Light at approximately 660nm falls within the red portion of the photosynthetically active radiation (PAR) spectrum. Plants can use this light during photosynthesis, making deep red an important component of many horticultural lighting systems.

The TotalGrow Deep Red Specialty Light Bar allows growers to add targeted 660nm output without installing another full-spectrum fixture. This can be particularly useful when an existing lighting system needs additional red-spectrum intensity or a different spectral balance to meet specific cultivation objectives.

Supplemental Lighting for Existing Grow Light Systems

The TotalGrow Deep Red Specialty Light Bar is specifically designed as a complementary horticultural fixture. It should be used with an appropriate primary grow light rather than treated as the sole lighting source for a cultivation area.

Its targeted spectrum makes it possible to fine-tune an existing lighting environment while avoiding unnecessary additional wavelengths. Growers can position the bars where supplemental 660nm light is needed and expand the installation using the modular linking system.

Modular Daisy-Chain Design

For larger indoor growing and greenhouse installations, multiple TotalGrow Deep Red Specialty Light Bars can be connected using compatible linking cables.

Maximum listed daisy-chain configurations are:

• 120V: Up to 24 light bars
• 240V: Up to 48 light bars
• 277V: Up to 55 light bars

This modular configuration allows growers to expand supplemental deep red lighting across cultivation areas while reducing the need for an individual power connection at every fixture. Appropriate linking cables and electrical requirements should be followed for the selected installation voltage.

Designed for Easy Integration

Measuring approximately 23.7 inches long, 2.3 inches wide, and only 1.5 inches high, the TotalGrow Deep Red Specialty Light Bar features a low-profile design that can fit into a wide range of cultivation environments.

Its compact dimensions make it suitable for installation alongside existing grow lights, between larger fixtures, within vertical farming racks, or in greenhouse lighting layouts where space and flexibility are important.

Ideal Applications

The TotalGrow Deep Red Specialty Light Bar is well suited for supplemental horticultural lighting applications including:

• Commercial greenhouses
• Indoor growing facilities
• Vertical farms
• Multi-tier cultivation racks
• Controlled-environment agriculture
• Research and plant-development facilities
• Supplemental photosynthetic lighting
• Red-spectrum supplementation
• Spectral balancing of existing grow light systems
• Existing full-spectrum grow lighting installations requiring additional 660nm output
