What is the Hi-Par Understorm 200W Bar LED used for?
This LED bar is designed as supplemental lighting—ideal for under-canopy, inter-row, or side lighting to boost lower plant growth. It's great for tents, racks, or greenhouses and improves canopy penetration, light uniformity, and overall plant quality.
Can I use the Hi-Par Understorm 200W from veg through flower?
Yes. The fixture offers a full-spectrum output that supports all growth stages. You adjust performance by changing placement, run time, and optionally using a dimmer or controller.
How efficient is the Hi-Par Understorm 200W Bar LED?
It delivers 2.52 μmol/J with a PPF of over 507 μmol/s, meaning excellent photon output for the power used. Its 120°+ beam angle ensures wide, even light spread across the canopy.
Will the Hi-Par Understorm increase heat, humidity, or feeding needs?
Yes. More light can raise canopy temperature and humidity, and boost water/nutrient demand. Use adequate airflow and monitor your environment closely to maintain balance.
Does the Hi-Par Understorm include a driver and support dimming?
Yes—it includes a 200W driver that can be mounted on the fixture or remotely. Some kits include manual dimmers, and it's compatible with the HI-PAR Control Station for advanced lighting control. You can also use a standard timer.
How do I install and position the Hi-Par Understorm?
It comes with tripod stands, hangers, and hardware. You can place it under, beside, or above the canopy. Adjust angle and distance to avoid bleaching, and reposition during the grow as plants stretch or fill out.
Is the Hi-Par Understorm 200W safe in wet or humid grow spaces?
Yes—it’s IP65 rated, meaning it's dust-tight and water-resistant (not waterproof). Avoid standing water near cables. Use drip loops and never submerge or blast it with water.
How should I clean the Hi-Par Understorm 200W Bar LED?
Turn off and unplug it first. Wipe down with a dry or lightly damp cloth. Isopropyl alcohol is fine if applied on a cloth, not sprayed. Avoid moisture near plugs or seals.
Why isn’t my Hi-Par Understorm working properly?
Check all power connections, the driver, and your timer. Flickering or dimming may be caused by poor connections or interference from controllers. Remove accessories to isolate the issue if needed.
When should I start using under-canopy lighting in my grow?
Use it when the canopy thickens and light stops reaching lower sites—typically in late veg or mid-flower. It’s not needed in early veg. Most growers run it during peak light hours only, not full cycle.
Does the Hi-Par Understorm 200W Bar LED reduce popcorn buds?
It helps. By improving light to lower sites, you’ll see better bud development. But you still need good canopy training, airflow, and defoliation to get consistent top-to-bottom results.
Is the Hi-Par Understorm suitable for tight spaces?
Yes. The slim bar form factor (approx. 1010mm x 95mm x 35mm) and low weight (2.9kg) make it perfect for small tents, tight racks, or awkward grow layouts where panels won’t fit well.
Can the Hi-Par Understorm be moved or used in multiple positions?
Absolutely. Many growers start with side lighting, then shift to under-canopy later. Its tripod stands and hangers make it easy to reposition as plant structure changes.
Do I need special glasses when using the Hi-Par Understorm?
It’s recommended. Like all high-output grow lights, it can be harsh on eyes, especially when used at close range. Avoid staring directly at the LEDs.
