What is the Digi-Lumen HALO 400W LED Grow Light used for?
The Digi-Lumen HALO 400W is a 6-bar full-spectrum LED grow light designed for the full grow cycle—seedlings to flower. It produces balanced white light (not blurple) and works well for hydroponics, houseplants, vertical farming, and greenhouse supplemental lighting.
What size grow space does the Digi-Lumen HALO 400W cover?
It’s ideal for a 1m x 1m flowering tent. You can use it in smaller spaces by dimming and raising the light, or in larger spaces as supplemental lighting. Coverage outside 1m² may have weaker edge intensity.
How much light does the Digi-Lumen HALO 400W produce?
It outputs up to 1080 µmol/s at full power with an efficiency of 2.7 µmol/J. That means more usable plant light per watt, helping you get strong growth without wasting power or generating excess heat.
Can I dim the Digi-Lumen HALO 400W for different grow stages?
Yes—it has built-in presets at 160W, 240W, 320W, and 400W. Use lower settings for seedlings or early veg, and increase intensity gradually. This helps prevent light stress, tacoing, or bleaching as your canopy fills in.
Can I use a lighting controller with the Digi-Lumen HALO 400W?
Yes—it supports 0–10V dimming control and can be linked to compatible controllers. You can also daisy-chain the control signal across multiple fixtures for synchronized dimming.
Is the Digi-Lumen HALO 400W easy to install?
Yes—it’s plug-and-play with a built-in driver and includes rope ratchets and wire hangers. You can mount it to tent crossbars or a ceiling frame. Just keep cords tidy and ensure solid support.
How far should I hang the Digi-Lumen HALO 400W above plants?
Start higher and lower gradually while monitoring plant response. If you notice leaf curl, bleaching, or stress, raise the light or dim it. A PAR meter helps dial things in, but isn’t essential.
Does the Digi-Lumen HALO 400W run hot?
It runs cooler than HID lights but still produces heat. Good extraction and canopy airflow are important—fans don’t need to blow directly on the fixture, but keep the grow space ventilated.
Is the Digi-Lumen HALO 400W safe to use in humid environments?
Yes—it’s rated IP45 and includes a moisture shield over the LEDs. It resists spray and humidity but isn’t waterproof, so don’t hose it or let water pool on the fixture.
How should I clean the Digi-Lumen HALO 400W?
Unplug it first, then gently wipe with a damp cloth. Avoid spraying cleaners or water directly onto the fixture. Keeping the light dust-free helps maintain output and longevity.
What is the size and build of the Digi-Lumen HALO 400W?
It measures about 580mm x 580mm x 38mm and weighs around 3.6 kg. The body is die-cast aluminium, which helps with heat dissipation and durability in grow environments.
How long does the Digi-Lumen HALO 400W last, and is there a warranty?
It’s rated for 50,000+ hours and backed by a 2-year warranty. If it stops working, check connections first, then contact support—don’t open the housing or attempt DIY repairs.
Can I use a timer with the Digi-Lumen HALO 400W?
Yes—most growers use it with a quality timer for light cycles. It doesn’t have a built-in sunrise/sunset mode, but this can be added via a compatible 0–10V controller.
Will the Digi-Lumen HALO 400W increase my yield?
It can—if the rest of your grow is dialled in. Strong light supports better yields, especially when combined with good airflow, canopy management, and nutrition. It also helps reduce seedling stretch when set correctly.
What’s the difference between PPF and PPFD?
PPF is total light output from the fixture (in µmol/s). PPFD measures how much light actually hits your plants (at a specific point). PPFD tells you what the canopy receives, which is what really matters for growth.
