The UR45 supplemental LED grow light bar: set has 2 bars, a total output of 45W, mainly used to supplement the UV and IR radiation when using white full-spectrum LED grow lights in indoor growing.

UV Grow Light - Ultraviolet To Maximize Your Yield: Supplemented to grow lights, UV (365-420nm) on UR45 supplemental light bars can induce larger leaf areas and promote light interception, thus significantly increasing plant production. Proper UV light for plants can also improve the nutritional quality of plants and stimulate biomass production by stressing them. (UVA band is less damaging to plant cells than the UVB band, while achieving the above effects)

IR Grow Light - Infrared To Regulate Plant Growth: IR (730-745nm) on UR45 supplemental light bars can work with far-red light to produce a shade-avoidance response in plants, thereby accelerating stem growth. The introduction of appropriate IR can induce plants to enter the flowering stage or to enter the sleeping stage more quickly.

Separate Control Of UV & IR: The UR45 supplemental light bars are equipped with a spectral switch that can be selected to turn ON/OFF UV light or IR light, respectively or simultaneously, for free configuration of the supplemental spectrum. Growers can use it as a UV grow light or an IR grow light according to the needs.

Easy Installation To Grow Lights & Shelves: Comes with brackets made specifically for Mars Hydro FC and FC-E LED grow lights and hooks for hanging from the top, making it easy and simple to use.
