The 4Seasons Quantum PAR 100W is a compact, seed-to-harvest LED grow light for small spaces. It packs Samsung LM301H EVO white diodes with OSRAM 660 nm red and 730 nm far-red onto a 30 × 25 cm board that flowers a 60 × 60 cm space and vegs up to 80 × 80 cm, on just 100W. It connects to your AC Infinity controller through the Type-A adapter, so even a small tent can run on the same schedule as the rest of your equipment. Stocked and supported in Sydney.
A small light with full-size diodes
Small grow lights are where manufacturers usually cut corners, and it shows in the diodes. The Quantum PAR uses the same class of parts as much larger fixtures: Samsung LM301H EVO whites across a 3000K + 5000K blend for a broad, balanced spectrum, plus OSRAM 660 nm deep red for flowering and fruiting and OSRAM 730 nm far-red to speed the switch into flower and support dense flower development.
The result is one light that takes a plant all the way from seedling to harvest in a small space — no swapping fixtures between veg and flower.
Where it shines
| 60 × 60 cm grow tent | The main light, seed to harvest |
| Cupboard or cabinet grow | The compact 30 × 25 cm board fits tight spaces |
| Mother plants and clones | Dim it back and it holds a veg or propagation space gently |
| Herbs, chillies and greens | A year-round kitchen garden on 100W |
Runs on your AC Infinity controller
The Quantum PAR has an RJ11 dimming port. Add a UIS Lighting Adapter Type-A ($44.95, sold separately) and it connects to a Controller 69, 69 Pro or Controller AI+, where it dims, schedules and ramps from the AC Infinity app alongside your fan and climate equipment.
It also has its own 0–100% dimmer on board, so it is fully plug-and-play without a controller. Dial the intensity or adjust the hanging height to suit each stage.

FAQ
Can it flower on its own?
Yes, in a 60 × 60 cm space. That is what it is designed for — one light from seed to harvest, with the OSRAM red and far-red doing the flowering work.
How high should I hang it?
Around 30 cm above the canopy at full power in flower, higher and dimmer for seedlings and clones. Start conservative and bring it down or turn it up as plants establish.
Does it work with AC Infinity controllers?
Yes — through the Type-A adapter into the RJ11 port. Controller 69, 69 Pro and Controller AI+ all work.
Can I add a second one later?
Yes. Two Quantum PARs side by side cover a 60 × 120 cm space, and both can run from one AC Infinity controller through a Type-A adapter each.
Is it supported in Australia?
Yes. Quick Bloom Lights stocks and supports 4Seasons here, ships from Sydney and handles the 2-year warranty locally.
