The Digi-Lumen Halo 400W is a 6-bar full-spectrum LED built for 1m x 1m tents, pushing 1080 µmol/s at 2.7 µmol/J from 1128 diodes. The driver is built into the fixture, the manual dimmer steps through 160W, 240W, 320W and 400W, and the 0–10V control ports let a controller run the dimming for you. A polycarbonate cover over the diodes and an IP45 rating handle the humidity of a working grow tent, and at 3.6kg it hangs off the lightest tent frame without a worry.

Only 2 units available — final run of the Halo 400W Digi-Lumen has moved this class to the new Extreme 400W, and these are the last two Halos we will stock. Both are brand new in box with the full 2-year warranty. This is the final price — it will not drop.
1080 µmol/s Full Spectrum Balanced white and red diode output covers seedling through flower without swapping spectrums, hitting 1394 µmol/m²/s PPFD at 30cm.
2.7 µmol/J Efficacy Strong efficiency for the wattage class — more of your power bill turns into usable photons instead of heat at the canopy.
Dimming + 0–10V Control Step through 160W, 240W, 320W and 400W on the manual dial, or wire the 0–10V ports to a controller for automated dimming and schedules.
Built-In Driver, IP45 Body No external driver to mount — one plug and it runs. Die-cast aluminium body and polycarbonate diode cover shrug off tent humidity.

Getting the most from your Halo 400W
  • Start seedlings and clones at 160W and step up as plants establish — full power too early stresses young plants.
  • Hang at 50–60cm for veg, then drop to 40–45cm in flower. Watch leaf tips for stress before going lower.
  • The 0–10V ports pair with a controller like the Digi-Lumen Enviro-Pro for automated dimming, sunrise/sunset ramps and temperature protection.
  • IP45 means humidity and spray resistance, not waterproof — keep the fixture above the canopy and away from direct water.

Setting Up

1
Attach the rope ratchets and wire hangers to the fixture and your tent's top bars.
2
Set the height — 50–60cm above the canopy is the right starting point for veg.
3
Dial the dimmer to your starting output — 160W for seedlings, higher as plants mature.
4
Optionally wire the 0–10V ports to a lighting controller for automated dimming and schedules.
5
Ramp to 320–400W through flower, dropping hang height to 40–45cm for peak PPFD.

FAQ

Is this the current Digi-Lumen 400W model?

No — Digi-Lumen has superseded the Halo with the Extreme 400W. These are the final two units we will stock: brand new in box, covered by the full 2-year warranty, at a final price that will not drop.

What tent size suits the Halo 400W?

A 1m x 1m tent is the sweet spot — the maximum recommended coverage is 1000mm x 1000mm. For 1.2m or 1.5m tents, step up to a larger Halo.

Is it dimmable?

Yes. A manual dial steps through 160W, 240W, 320W and 400W, and the 0–10V control ports allow automated dimming from a compatible controller.

Does it need an external driver or ballast?

No. The 400W driver is built into the fixture — plug it into a standard Australian outlet and it runs.

Can I use it for both veg and flower?

Yes. The full-spectrum white and red output covers the whole cycle — run lower dimmer settings through veg and full power through flower.

Is it water resistant?

Yes, to IP45 — protected against spray and grow room humidity, with a polycarbonate cover over the diodes. It is not waterproof, so keep it out of direct water contact.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
