LED GROW BAR

SpectraB.2.G X90 120 cm – the full spectrum LED grow bar that takes your plants from seed to harvest

Designed in France by the BloomLED team, the SpectraB.2.G X90 is a 120 cm / 90 W horticultural LED bar built for demanding indoor growers. Its full SAMSUNG + CREE spectrum, integrated dimmer and fully passive cooling make it a silent, durable, ruthlessly effective tool for mastering photosynthesis at every stage of the cycle.

With 10+ years of expertise in horticultural LED lighting, BloomLED designed the SpectraB.2.G range to solve one clear need: give indoor cultivators a linear, modular, reliable light that matches fixed-panel output without inheriting its flaws. Thanks to its elongated form, the SpectraB.2.G X90 drops neatly into rectangular grow tents, fills shadowy corners and stacks seamlessly with other bars to cover any footprint.

Why the SpectraB.2.G X90 stands out

🌱 Full SAMSUNG + CREE spectrum

A photosynthetically rich light distribution that covers vegetative growth and flowering without any gap. SAMSUNG LM301 diodes deliver top-tier µmol/J efficacy, while CREE diodes bring the PAR density required to push bloom-stage yields and secondary metabolite production. One light, whole cycle, zero spectral compromise.

💡 Ultra-efficient 90 W bar

At a true 90 W across 120 cm, the SpectraB.2.G X90 delivers a uniform linear light density perfect for rectangular footprints. Controlled power draw means high PPFD with moderate heat: less cooling stress on your plants, and an electricity bill that stays sensible even on a full bloom cycle.

🎚️ Built-in 0-100 % dimmer

Tune light intensity to each growth stage: 30 % for seedlings and clones, 70-80 % during veg, 100 % in full flower. The integrated potentiometer removes the need for any external controller and simplifies day-to-day management. You decide the exact DLI your canopy receives.

🌡️ Fully passive cooling

No fan, no noise, no wear part. The extruded aluminium housing dissipates heat silently and maintenance-free. Perfect for home setups, living rooms or noise-sensitive environments. Operating temperature stays stable even on 18/6 photoperiods and long cycles.

🔗 Modular Plug & Grow

Shipped ready to plug in, the bar installs in under five minutes with the supplied hangers. Line up several side by side to cover 80×80, 100×100 or 120×120 tents: the linear form factor lets you mix and match to the exact dimensions of your grow space. No external driver, no complex wiring.

🛡️ 2-year BloomLED warranty

Built around a premium PCB and carefully selected components, the SpectraB.2.G X90 comes with a 2-year warranty backed by our France-based support team. A horticultural LED specialist for 10+ years, BloomLED stands behind every grow with expert advice, spare parts and hassle-free RMAs.

Recommended setups by tent size

The beauty of a grow bar lies in its modularity. Here are the configurations our community uses most successfully: in a 60 × 60 cm tent, a single SpectraB.2.G X90 centred over the canopy delivers great PPFD for 1–2 plants run as SOG. In an 80 × 80 cm tent, pair two X90 bars spaced 35-40 cm apart for a remarkably even light map, ideal for ScrOG. In a 100 × 100 cm tent, three parallel X90 bars cover the full footprint with no shadow zones. For 120 × 120 cm tents and above, add a UV or IR supplemental bar in late bloom to stimulate resin production and flower density.

💚 Bottom line: a 120 cm, 90 W full spectrum LED grow bar – silent, dimmable, designed in France to last and to perform, from seed to harvest.

Frequently asked questions

What coverage does a single SpectraB.2.G X90 provide?

In optimal conditions (≈ 50 cm above the canopy, dimmer at 100 %), the SpectraB.2.G X90 covers a rectangular zone of up to 140 × 40 cm. For 80×80 or 100×100 cm tents we recommend combining 2 to 3 bars to achieve a perfectly uniform light map and eliminate shadow zones near the edges.

How far above the plants should the bar hang?

Cloning/seedling stage: 60-70 cm with dimmer at 30-40 %. Vegetative: 50-60 cm at 60-80 %. Flowering: 40-50 cm at 100 %. Watch your plants: leaves curling slightly upward indicate too much light or too close a bar. Flat leaves and short internodes signal a correct distance.

Is this bar enough for the whole cycle?

Yes. Its full spectrum output (broad white + deep reds) is engineered to cover both veg and bloom with a single source. You do not need to swap lights between stages: adjust the dimmer and the hanging height. To maximise trichome density, add a UV bar in the last two weeks of bloom.

What is the real power consumption?

The SpectraB.2.G X90 draws a true 90 W at full output. On an 18/6 veg schedule that works out to about 1.62 kWh/day; on 12/12 bloom, roughly 1.08 kWh/day. A balanced efficiency profile that keeps your meter quiet, especially since the dimmer lets you run lower wattages during the first weeks of growth.

Can I combine several SpectraB.2.G bars for a larger setup?

Absolutely, and we actively recommend it. SpectraB bars are engineered to be modular: chain several X90 120 cm units, complete the setup with a UV or IR bar to push bloom, and raise light density without creating hot spots. Each bar has its own integrated driver and its own dimmer for independent control.
