We'll only email you about this product — no marketing.
The Pure LED Q150 is a 150W full-spectrum LED grow light from Pure Factory, built specifically for growers working with 60–80 cm tents, cupboards, and micro grow boxes. Packing Samsung LM281B+ PRO diodes into a compact 357 × 357 mm panel, it delivers 2.7 µmol/J efficiency — meaning more usable light per watt and less money disappearing into your electricity bill. If you're growing in a small space and want proper light without the heat headaches, this is the lamp we'd reach for first.
Knowing exactly what arrives in the box matters — especially when you're planning a tight setup. The Q150 ships ready to hang with everything you need to get started:
The panel itself weighs 2.8 kg — light enough to hang from tent crossbars without worrying about structural integrity, but solid enough in the hand that you can feel the aluminium heatsink doing its job. No plastic housing pretending to be professional gear here.
Small grow spaces are unforgiving. You've got limited headroom, restricted airflow, and every degree of heat matters. Most growers who start with a 60x60 or 80x80 tent make the same mistake: they either underpower their canopy with a cheap blurple panel, or they cram in a light that's too hot and too hungry for the space. We've seen both play out hundreds of times.
The Pure Factory Q150 sits in a sweet spot that actually makes sense for compact setups. At 150W true wall draw, it produces enough photosynthetically active radiation (PAR) to drive both vegetative growth and flowering without turning your tent into a sauna. The 4000K white plus 660nm red spectrum covers the full range your plants need — no swapping bulbs between growth stages, no supplementary red panels bolted on as an afterthought. One light, both phases, done.
The honest limitation? At 150W, you're realistically covering a 60x60 cm footprint well and an 80x80 cm footprint adequately. If you're eyeing a 100x100 tent or larger, you'll want to step up to the Q240 or Q320 in the Pure LED range. The Q150 doesn't pretend to be something it isn't — and that's exactly why it works so well in the space it's designed for.
The component list on this light reads like something from a panel twice the price. The Q150 runs 576 Samsung LM281B+ PRO LEDs — the same diode family used in professional horticultural lighting — alongside 42 Honglitronics SMD3535 deep-red diodes for that 660nm flowering boost. Samsung's LM281B+ line is known for maintaining output over thousands of hours; these aren't the mystery-brand LEDs that dim noticeably after one grow cycle.
Pick it up and you'll notice the weight sits in the heatsink — a passive aluminium design that dissipates heat without any fans. Zero fans means zero noise. You can run this light in a bedroom cupboard at 2 AM and the only sound you'll hear is your own breathing. The IP65 rating means it handles humid grow environments without flinching — splashes, condensation, the works. That rating is genuinely useful, not just a spec-sheet flex, especially if you're growing in a tent where humidity regularly sits above 60%.

The Q150 is the entry point in Pure Factory's quantum board lineup. Choosing the right wattage comes down to tent size — nothing more complicated than that. Here's how the range breaks down:
| Model | Wattage | Best tent size | Diode count |
|---|---|---|---|
| Pure LED Q150 | 150W | 60 × 60 to 80 × 80 cm | 576 Samsung + 42 Honglitronics |
| Pure LED Q240 | 240W | 100 × 100 cm | Higher diode count, same platform |
| Pure LED Q320 | 320W | 120 × 120 cm | Higher diode count, same platform |
We'd pick the Q150 over a generic 150W panel every time for one reason: the 2.7 µmol/J efficiency figure. Cheap panels claiming 150W often deliver half the usable PAR because they're running inefficient diodes at high current. The Samsung LM281B+ chips in the Q150 run cool and efficient — you get more light on your canopy for the same electricity cost.
The Q150 runs noticeably cooler than similarly rated panels we've had on the shelf. In a 60x60 tent with the flap open for 30 seconds, you can hold your hand directly under the panel without discomfort — try that with an old-school HPS in the same space and you'll pull back fast. That low heat output means less load on your extraction fan and less risk of heat stress during summer months when ambient temperatures climb.
One thing to keep in mind: the 120° beam angle is wide by design, which is brilliant for even canopy coverage in small tents but means light intensity drops off faster at the edges compared to a narrower-beam panel. In an 80x80 tent, the outer 10 cm of your canopy will receive noticeably less PAR than the centre. If you're growing a single large plant with LST training to fill the space, this matters less. If you've got four pots pushed into the corners, the corner plants will stretch slightly more. It's not a dealbreaker — just worth knowing so you can plan your layout accordingly.
Complete your setup: pair the Q150 with a Dark Box 60x60 grow tent and a carbon filter extraction kit for a self-contained growing environment. If you're starting from seed, a propagation heat mat under your seedlings will speed up germination before the Q150 takes over lighting duties.
At 150W running 18 hours a day during veg, the Q150 draws roughly 81 kWh per month. During a 12/12 flowering cycle, that drops to about 54 kWh. Compared to a 250W HPS doing the same job, you're saving 40% on electricity for comparable — often better — light output.
Yes. The full spectrum (4000K white plus 660nm red) covers both stages. No need to swap bulbs or add supplementary panels. Use the dimmer to run lower intensity during veg and full power during flower.
Not at all — it's completely silent. The Q150 uses a passive aluminium heatsink with no fans. Zero moving parts means zero noise. You can run it in a bedroom without hearing a thing.
It's designed for 60 × 60 cm tents and works well up to 80 × 80 cm. Beyond that, light intensity at the edges drops noticeably. For a 100 × 100 cm tent, step up to the Pure LED Q240.
Very little compared to HPS or cheap LED panels. The passive heatsink keeps surface temperatures low. In a 60x60 tent with decent extraction, the Q150 adds only a few degrees to ambient temperature — a major advantage during warm months.
It measures how much usable plant light (photons) the LED produces per joule of electricity consumed. At 2.7 µmol/J, the Q150 converts energy into light very efficiently — on par with professional horticultural fixtures. Higher efficiency means more growth per watt and lower running costs.
Yes. It has a built-in manual dimmer with stepless adjustment. It's also compatible with any external 0–10V signal controller, so you can integrate it into automated climate systems if your setup uses one.
It carries an IP65 rating, meaning it's protected against water jets from any direction. It handles humid tent environments, condensation, and accidental splashes without issue. Don't submerge it, obviously — but normal grow-room humidity won't cause problems.
