The Digi-Lumen Extreme 780 W Dual Spectrum is the 1.5 × 1.5 m fixture with the extra spectrum control — 2340 µmol/s at 3.0 µmol/J from 2412 diodes across six bi-fold bars, with 72 UV-A diodes at 395 nm and 72 far-red at 730 nm on their own separately dimmable channels. Same footprint and same frame as the Extreme 720 W, a little more output, and two spectrum channels you control yourself. The 780 W driver is built in, and with an AC Infinity Type-A adapter it runs off the same UIS controller as the rest of your tent.

Dual Spectrum: UV and far-red you control yourself
Most fixtures give you one spectrum and one dimmer. This one gives you three. The main array is 2160 white 4000 K plus 108 deep red 660 nm — the photosynthetic workhorse. On top of that sit 72 UV-A diodes at 395 nm and 72 far-red diodes at 730 nm, each on its own channel with its own manual control, so you decide when they run and how hard.
That separation is the point. UV-A and far-red are supplementary tools rather than things you leave on all cycle — growers typically bring them in at specific stages rather than running them flat out from day one. Digi-Lumen publish a dedicated guide on using the UV and far-red channels, and we would rather point you at that than make claims about results we have not measured ourselves. If you want to talk through how to phase them in, get in touch.
Six bars, even photons corner to corner
Six bars spread across a 1120 × 1060 mm frame, each diode throwing a 120° beam so the cones overlap before they reach the canopy. Digi-Lumen measure 1276 µmol/m²/s at 30 cm across a 5 × 5 grid, and the bar layout is what keeps that reading holding up as you move out towards the edges — the plants in the corners get treated like the ones in the middle.
The driver is built in
A 780 W high-frequency driver sits inside the fixture's spine. Nothing to mount on the tent pole, no low-voltage lead to route, one power cord per light. Cleaner install, fewer connections to work loose, and at 7.5 kg it is light enough to hang and adjust on your own.
The frame folds in half for storage and transport. Iron frame with an aluminium heat sink, passively cooled, IP45 rated for dust and moisture, and rated to run anywhere from -25°C to 40°C.
Runs on your AC Infinity controller. The whole Digi-Lumen range works with AC Infinity's UIS system through the
UIS Lighting Adapter Type-A. Plug the adapter into the fixture's control port and into a Controller 69, 69 Pro, 69 Pro+ or AI+, and your photoperiod and dimming run off the same controller as your inline fan, humidifier and heater — one schedule, one app, one place to change it. No separate lighting timer, no second system to learn.

FAQ
How is this different from the Extreme 720 W?
Same 1.5 × 1.5 m footprint, same six-bar bi-fold frame, same 3.0 µmol/J efficacy. The 780 W adds two things: a bit more output — 2340 µmol/s against 2160 — and the UV and far-red channels, which the 720 W does not have. If you want the extra spectrum control, this is the upgrade. If you just want a well-lit 5×5 at the best price, the 720 W does that job properly and we will happily say so.
Do I have to run the UV and far-red channels?
No. They are on separate controls and you can leave them off entirely — the fixture still delivers a full-spectrum 1.5 × 1.5 m canopy without them. They are there for when you want to experiment, and Digi-Lumen's channel guide is the place to start.
Is UV at 395 nm safe to be around?
395 nm is UV-A, the long-wavelength end — not the UV-B or UV-C used in sterilisation. It still makes sense to avoid looking directly into any high-output fixture and to keep exposure sensible when you are working in the room with the channel running. Wear eye protection if you are going to be in there for a while.
What do I need to run it off an AC Infinity controller?
Two things: a UIS Lighting Adapter Type-A (AC-ADL7) and a UIS controller — Controller 69, 69 Pro, 69 Pro+ or AI+. The adapter plugs into the control port on the light and into a UIS port on the controller, and from there the light behaves like any other UIS device: same schedule, same app, same place you set your fan and humidifier. If you are putting a whole tent together, tell us what is going in it and we will put the parts list together for you.
Do I need CO2 to get the most out of it?
No. At 2.25 m² the 780 W is well matched to what plants can use in ordinary room air. If you do run CO2, enriching the room lets plants convert more light into growth and the fixture will reward it, but this is not a light that needs a sealed room to make sense.
What does the 3.93 A draw mean for my circuit?
At full output it pulls just under 4 A on a 240 V supply, so a single fixture plus a fan and a humidifier sits comfortably on a standard 10 A outlet. For two or more lights on one circuit, have a licensed electrician confirm the load before install day.
How does it handle a humid grow room?
Well. It is IP45 rated against dust and splashing water from any direction and runs anywhere from -25°C to 40°C, so a working tent at high humidity is exactly the environment it was built for. It is not designed for submersion or direct hosing, so keep the wash-down away from it.
Is it covered by an Australian warranty?
Yes. Two years, backed by Quick Bloom Lights here in Sydney. If something goes wrong you deal with us, not an offshore seller.
