Extreme 200 W Under Canopy Light by Digi-Lumen - targeted LED canopy penetration
DL-EXT200-UL-KIT

Pairs well with
Dense canopies eat overhead light before it reaches the bottom. The result is the same every time — weak lower bud sites, uneven density, and yield left on the table. The Digi-Lumen Extreme 200W is a dedicated under-canopy bar that puts 600 µmol/s of targeted photon output exactly where your top light can't go. Slim enough to position between pots or rows, powerful enough to actually drive photosynthesis in the understory. Available as the light on its own, or as a complete kit with adjustable stand and power lead included.

What's Included
Technical Specifications
- Introduce under-canopy bars at the flip to flower — this is when canopy density increases and lower sites start losing overhead light access.
- Position the bar 20–40 cm from lower bud sites, aimed horizontally or at a slight upward angle into the understory. Pointing straight down at soil achieves nothing.
- Run it on the same photoperiod as your main lights. Never run supplemental lighting independently during flower — light leak through the dark period causes problems.
- Combine with adequate under-canopy airflow. Light plus moving air converts shaded sites into productive flower zones. Without airflow you just create a warm, humid pocket.
- For multiple rows, space bars evenly between each row rather than clustering them. Consistent distribution across the understory produces even harvest weight across every plant.
How to Set Up Under-Canopy Lighting
Pairs Well With
The natural top-light partner. The Halo 1000W handles the canopy — the Extreme 200W handles what the Halo can't reach underneath.
Side Bar 250W by Digi-LumenCovers the side canopy angles the Extreme 200W doesn't target. Run both for full-plant coverage — top, sides, and understory.
Clip Fans & Air CirculationUnder-canopy lighting works best with under-canopy airflow. Light plus moving air converts shaded lower sites into productive flower zones.
Environment ControllersRunning multiple bars? An environment controller lets you sync all lighting zones from one device — schedules, dimming, and temperature response.
Inline & Exhaust FansAdding 200W to your room adds to total heat load. Make sure extraction is sized for your full wattage — top lights plus supplemental combined.
Grow TentsUnder-canopy lighting pays off most in dense, tall setups. Standard-height and shaq-size tents with full canopies are where this bar earns its keep.
Frequently Asked Questions
What is the difference between the Underlight 200W and the Single Light Kit?
The Underlight 200W is the light bar on its own — you supply your own stand and power lead. The Single Light Kit includes the light bar, an adjustable stand, and a power lead — everything to deploy the bar straight out of the box. If you're adding a second bar to an existing setup, the light-only option makes sense. First-time buyers are better off with the kit.
Can this be used as a standalone primary grow light?
No — not for any serious flowering application. The Extreme 200W is purpose-built as a supplemental under-canopy fixture. At 200W and 600 µmol/s it doesn't produce enough PPFD to be a standalone primary light. It will support early vegetative growth in a small space, but for a primary fixture look at the Halo 400W or above.
When should I start running under-canopy lighting?
Most growers introduce under-canopy bars at the flip to flower, when canopy density increases and lower sites begin losing direct overhead light access. Running it through veg doesn't hurt, but the gains are most significant from the point your canopy closes and creates consistent shade underneath.
How many bars do I need?
It depends on row spacing and plant density. For a 1.2 x 1.2 m tent with one or two rows, one bar centrally positioned is usually sufficient. For 1.8 x 1.8 m or larger with multiple rows, one bar per row gap produces the most even understory coverage.
Does it need a controller or special wiring?
No. Plug and play — connect to a standard Australian mains outlet and it runs. For multi-bar setups, it's compatible with the Digi-Lumen ECO Smart Controller for centralised scheduling and dimming, but that's entirely optional.
Will it burn lower leaves if positioned too close?
Yes, it can if positioned too close without adequate airflow. Watch for leaf tacoing, bleaching, or faster-than-usual drying at lower leaf surfaces. Keep at least 20 cm from plant material and ensure there's air movement in the lower canopy zone. Always check during the first 48 hours of operation.
Is under-canopy lighting worth it if I'm already running a high-powered top light?
Yes — in most cases. Even a 1000W top light cannot penetrate a dense canopy uniformly. Lower sites always receive less light than the top regardless of how powerful your main light is. Under-canopy bars directly address this. The gains show up as better bud density uniformity, less popcorn from the lower plant, and more consistent harvest weight.
