Digi-Lumen build straightforward, well-made LED grow lights and publish every number behind them. The Extreme range runs at 3.0 µmol/J from the 60 W propagation bar all the way to the 1000 W XL — the same photons-per-watt whether you are lighting a single tray or a 4.5 m² room. Every fixture has its driver built in, so there is no ballast box to mount and no low-voltage lead running across the floor.
We stock the whole line: top lights, side bars, under-canopy bars, clone bars and the accessories that go with them. Everything ships from Sydney with a two-year warranty we handle ourselves.

Not sure where to start? The Extreme 720 W.
It is the one we keep on the shelf in Sydney and the one most people end up with. 2160 µmol/s over a 1.5 × 1.5 m canopy is the size of room most growers actually have, it runs at the same 3.0 µmol/J as the fixtures twice its price, and because we hold stock it goes out quickly rather than coming in on order. If your space is bigger or smaller, the table below will point you to the right one.
Pick by the size of your space
If your space is not on that list, or you are between two sizes, send us the dimensions and we will tell you which one fits. It is a two-minute conversation and it beats guessing.
More than the light above the plants
A top fixture works downwards, and the lower canopy gets whatever is left. Digi-Lumen build two answers to that, and both are worth a look once your main light is sorted.
Extreme 250 W Side Bars — 750 µmol/s across two 1120 mm bars, mounted vertically down the sides of a tent or laid under the canopy. Mounting hardware for tents and walls is on the site too.
Extreme 200 W Under-Canopy Bar — 600 µmol/s from a slim 1090 mm bar, rated IP65 because it lives down at pot level among the runoff. A cooler 6500 K spectrum with far-red, chosen for driving lower bud sites rather than duplicating the top light.
Starting from seed or cuttings
Clone bars come two to a carton in 1120 mm and 610 mm lengths, at 6500 K and low enough heat to sit close above a humidity dome. Once seedlings are established, the Extreme 60 W bar steps up the intensity at full 3.0 µmol/J efficacy, with an A-frame stand if you are working on a bench rather than in a tent.
They run on your AC Infinity controller. The dimmable fixtures in the range — the Extreme top lights from 400 W to 1000 W XL, plus the 200 W under-canopy bar and the 60 W bar — work with AC Infinity's UIS system through the
UIS Lighting Adapter Type-A. Plug it 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, no separate lighting timer — which is a rare thing to be able to say about a third-party light.
One exception worth knowing: the
clone bars have no dimming input. They daisy-chain to each other for power but they are on/off only, so a lighting adapter does nothing for them. To put them on the same schedule as the rest of the room, a
UIS Control Plug switches them at the outlet from the same controller.
A word on comparing efficacy
µmol/J is the honest way to compare grow lights — photons out per watt in — and it is the number worth checking on any fixture you are considering. Digi-Lumen publish it on every model, which not every brand does.
One thing worth knowing: the clone bars sit at 2.1 µmol/J rather than 3.0. That is not a lesser product, it is a different job. At 18 to 25 watts a bar, efficiency is irrelevant — what matters for cuttings is a cool, even, low-heat spread of light, and that is what those bars are engineered to deliver. Save the efficiency argument for the fixture that runs your flowering room.
