SpectraWILD S320 - Full Spectrum LED Grow Light Bars 320W Samsung - 80x80 Tent

SpectraWILD S320: 320W of Full Spectrum LED Bars Built for 80x80 Grow Tents

Designed in France by BloomLED, the SpectraWILD S320 combines four 80W horticultural LED bars fitted with Samsung top-bin diodes and OSRAM deep red emitters. Delivering 2.7 µmol/J, cooled entirely passively and dimmable out of the box, it turns an 80x80 cm tent into a genuinely high-performance indoor growing space. Ten years of grow shop expertise in one ready-to-hang kit.

A Bar Layout Engineered for Even Coverage

Every indoor grower knows the weakness of single-panel LED fixtures: a hot spot under the middle and dim corners. The SpectraWILD S320 answers with four independent bars you spread across the full footprint of the tent. Light no longer radiates from one point but from four parallel lines, which smooths PPFD distribution right across the canopy.

In practice, plants sitting at the edges receive an intensity close to those in the centre. You get a level canopy, evenly sized tops and far less training work to compensate for uneven growth. Across an 80x80 cm footprint, that consistency often matters more to the final result than a handful of extra watts.

A True Full Spectrum, From Cuttings to Late Flower

The S320 is full spectrum in the strict sense: it covers the entire PAR range, from 450 nm blue through to 660 nm deep red, with a white continuum that closely mimics sunlight. Samsung LM301 diodes provide the high-efficiency white base, while OSRAM deep red LEDs reinforce the band that photosynthesis relies on most during flowering.

One spectrum carries you through the whole cycle: no lamp swap between veg and bloom, no compromise. In vegetative growth the blue content keeps internodes tight and structure compact. In flower, deep red supports bud development and final density. The natural white rendering also means you actually see your plants, so spotting a deficiency, early water stress or a pest is immediate.

2.7 µmol/J: What Efficiency Means on Your Bill

Photon efficacy measures how many micromoles of light a fixture produces per joule of electricity consumed. At 2.7 µmol/J, the SpectraWILD S320 sits at the upper end of the LED bar market. In plain terms, every watt drawn from the wall is converted into light the plant can use rather than heat you have to remove.

Compared with a traditional 400W HPS, the S320 draws around 20% less power while spreading light far more usefully across the canopy. The saving shows up on your electricity bill, but also in thermal management: less waste heat means a slower extractor fan, less noise and a more stable tent temperature through summer.

Built-In Dimmer and 0-10V Control

A potentiometer is integrated directly into the Meanwell driver, so you can dial power down by hand with no accessories, easing young plants in before ramping up to the full 320W in peak flower. That control is essential after transplanting or when running fragile cuttings.

For deeper control, the S320 accepts the standard 0-10V protocol. Paired with the SmartWILD console (sold separately) you unlock Wi-Fi app control: day/night scheduling, gradual sunrise and sunset ramps, remote intensity adjustment and multi-fixture management from a single interface. The sunrise ramp is more than a gimmick; it avoids the abrupt light shock at switch-on and reduces plant stress.

Passive, Silent and IP65 Rated

Heat dissipation is entirely passive, handled by the aluminium bar profiles with no fan anywhere in the fixture. That means no added noise in the room, no dust being blown across the optics and, crucially, no moving part waiting to fail after a couple of seasons.

The IP65 rating protects the fixture against water jets and ambient humidity. You can foliar spray with confidence, run 70% RH through vegetative growth and clean the tent without worrying. The remote Meanwell power supply underpins that reliability: a benchmark name in power electronics, it delivers stable voltage and sits at the heart of the 3-year warranty covering the whole kit.

Setting Up in an 80x80 or 100x100 Tent

The S320's optimal footprint is 80x80 cm, where it delivers its highest PPFD and best output per watt. It will also cover a 100x100 cm tent with slightly more spread-out intensity, which suits SCROG setups or less light-hungry varieties well.

Hang the bars roughly 40 cm above the canopy in flower, and higher early in the cycle with the dimmer turned down. The included pulley kit makes height adjustment quick as the plants grow. The kit ships complete and ready to run: four S320 bars, the sealed power supply, the mounting frame with pulley hanging kit, an EU power cable and the assembly manual. Nothing else to buy to get started.
