Supplemental UV and IR four bar light set

$120
Last updated 2026-11-03

This set includes four bars designed to provide supplemental light spectrums to an existing setup. Two bars focus on ultraviolet light while the other two provide infrared wavelengths. These additions help mimic natural sunlight more closely than standard white LEDs alone. The bars measure 35.4 in in length, making them suitable for medium to large growing areas.

The design allows for flexible placement within a grow tent or greenhouse. By adding specific UV and IR frequencies, growers can influence plant development and resin production during different growth stages. These bars are built to work alongside primary full-spectrum lights to fill in the gaps that standard lighting might miss during the flowering phase.

Installation is straightforward with the included mounting hardware. The slim profile of the bars ensures they do not take up much vertical space, allowing for maximum plant height. The durable construction is intended for the humid environments often found in indoor gardens. This set offers a targeted way to enhance the light quality for specialized botanical projects.
