Meet the HI-PAR Understorm LED — advanced under-canopy horticultural lighting designed to drive light directly into the canopy where it counts. This powerful 200W full-spectrum fixture is built to boost both vegetative and flowering performance by improving light distribution below and through the plant structure.
The Understorm is seriously versatile: use it for under-canopy, inter-row, side lighting, or even as a compact top light. With a rugged housing and IP65 rating, it’s made for real grow environments—humid rooms, intensive schedules, and long-term use.
To make setup easy, it includes a HI-PAR Understorm Manual Dimmer plus stands and hanging hardware so you can mount it exactly where your garden needs it.
