TotalGrow™ UVA Specialty Light Bar – 24in 30W 385nm UVA Supplemental Grow Light

The TotalGrow™ UVA Specialty Light Bar is a 24-inch, 30-watt supplemental horticultural light designed to deliver targeted 385nm UVA light to indoor growing facilities and greenhouses. Supplemental UVA can support plant photoreceptor activity associated with desirable crop characteristics including coloration, aroma, density, and overall crop quality.

Producing 45 µmol/s of output with an efficacy of 1.5 µmol/J, the TotalGrow UVA Specialty Light Bar provides growers with a practical way to introduce targeted UVA into an existing horticultural lighting program without replacing their primary grow lights.

Its slim 23.7-inch linear design makes the fixture easy to integrate above or alongside existing lighting systems. Daisy-chain capability allows multiple UVA light bars to be connected for scalable installations, making it suitable for everything from individual growing areas to larger commercial greenhouse and indoor cultivation systems.

The fixture features a 100–277VAC input range, IP65 protection, ETL certification, projected 30,000-hour service life, and a 3-year warranty. A 120V power cord and two suspension hangers are included for convenient installation.

What Is the TotalGrow UVA Specialty Light Bar Used For?

The TotalGrow UVA Specialty Light Bar is designed to provide supplemental 385nm UVA radiation as part of a broader horticultural lighting strategy. Rather than serving as a primary source of photosynthetic light, the fixture complements existing grow lighting by exposing plants to a targeted UVA wavelength.

Growers may incorporate UVA supplementation to influence plant photoreceptor responses and support crop characteristics such as color development, aromatic expression, plant density, and overall crop quality. The appropriate exposure schedule will depend on crop type, growth stage, existing lighting conditions, and cultivation objectives.

385nm UVA Supplemental Lighting for Plants

The TotalGrow UVA Specialty Light Bar produces light at a targeted 385nm UVA wavelength. UVA occupies a different portion of the electromagnetic spectrum than the photosynthetically active wavelengths supplied by most primary horticultural fixtures.

Because of this, the UVA Specialty Light Bar should be viewed as a supplemental horticultural lighting tool rather than a standalone grow light. It can be paired with compatible full-spectrum or other primary grow lighting systems when growers want to introduce UVA exposure into a controlled cultivation program.

Designed for Easy Integration and Expansion

At only 23.7 inches long, 2.3 inches wide, and 1.5 inches high, the TotalGrow UVA Specialty Light Bar has a compact profile that makes it easy to incorporate into existing grow rooms, greenhouse structures, shelving systems, and lighting layouts.

The fixture's daisy-chain capability allows growers to expand UVA coverage across multiple bars instead of powering every fixture independently. This modular approach is especially useful for commercial installations where UVA supplementation needs to be extended across larger growing areas.

Ideal Applications

The TotalGrow UVA Specialty Light Bar is designed for complementary and supplemental horticultural lighting applications including:

• Indoor growing facilities
• Commercial greenhouses
• Controlled-environment agriculture
• Vertical farming systems
• Multi-tier growing racks
• Research and plant-development facilities
• Supplemental UVA lighting programs
• Crop quality and morphology management strategies
• Existing full-spectrum grow light installations requiring UVA supplementation
