The TotalGrow UVA Bar generates 385nm UVA light with exceptional efficiency and reliability in an ideal form factor for simple utilization. Standard grow lights emit little or no UVA radiation. UVA stimulates several plant photoreceptors that enhance hardiness, coloration, tastes, smells, density and potency. Combine with sunlight and/or TotalGrow full spectrum lights for ideal growth! Ultraviolet-A Light for Enhanced Crop Quality 30W of highly efficient, reliable LED UVA lighting Stimulate growth quality and hardening responses missed by standard lights Thin, narrow profile for simple, versatile utilization Why UVA? Approximately 5% of solar radiation reaching the earth is ultraviolet-A (320-400nm). These light wavelengths drive relatively little photosynthesis, but trigger other responses in plants, primarily defense mechanisms. Comparable to human skin becoming tan, plants produce anthocyanins and other valuable nutrients and chemicals to become stronger. UV radiation is absent from most grow rooms and greenhouses because of UV-filtering glazing materials and the lack of UV in most grow lights. Supplementing with TotalGrow UVA Bars will enhance many quality aspects of your plant growth in these situations Spectrum Usage Guidelines Brochure Brochure Product Specs Spec Sheet Specs Wattage draw: 30 watts Beam Angle: 120 degrees Spectrum: 385nm PAR Efficacy: 1.5 umol/J Light Output: 45 µmol/s Service Life: 30,000 hours Daisy Chain: Yes, up to 48 lights Coverage area and hanging height: See chart below Input voltage: 100-277 VAC Power frequency: 50 ~ 60Hz Input Current at min/max VAC (A): 0.3/0.1 Product weight: 2.3 lbs Dimensions: 23.7" (L) or 2.3" (W) x 1.5" (L) Additional details: IP65 wet-rated (waterproof) Daisy Chain: Up to 24 (120v) or 48 (240v) lights Product includes: Light Bar, power cord Recommended for: Commercial applications Home grows Tents Nurseries Hydroponics Arboretums, Schools, Universities, Research Institutes Manufacturer's warranty: 3 years
