Pack description
Pack of 6 SpectraB.2.G X45 60cm LED grow bars — light every corner of your tent
This Pack of 6 SpectraB.2.G X45 60cm horticultural LED bars is built for serious growers who want a truly uniform photon distribution across a large indoor canopy. Each LED grow bar runs a full-spectrum recipe tuned for every stage — from cutting to harvest booster. Mounted together, the six bars cover up to 80×240 cm, ideal for a 80×240 grow tent or two 80×120 modules side by side. BloomLED build quality, tested assembly and Plug & Play wiring mean you connect and start growing.
| Feature | Detail |
|---|---|
| Contents | 6× SpectraB.2.G X45 60cm |
| Bar length | 60 cm (56 cm active) |
| Power | 270 W combined (45 W × 6) |
| Spectrum | Full spectrum (white + red), 3000 K + 660 nm |
| Coverage | Up to 80×240 cm (flower) / 100×280 cm (veg) |
| Wiring | Plug & Play daisy-chain |
| Power supply | 230 V — driver included |
| Warranty | 2 years — BloomLED France support |
🌱 Optimised full spectrum
Each SpectraB.2.G X45 bar blends premium 3000 K white LEDs with 660 nm deep-red photons to support every grow phase — germination, cutting, vegetative growth and intense flowering. A PAR recipe calibrated for demanding indoor plants.
📐 Uniform canopy coverage
The six bars spread photons evenly across the full width of your grow tent. No more shaded corners or stretching tops: PPFD stays consistent across an 80×240 cm canopy — ideal for grow tents or rolling tables.
🔌 True Plug & Play install
No complex wiring: one EU 230 V cable, fast daisy-chain connectors between bars, and you are up and running in under 15 minutes. Designed for growers who want to focus on the plants, not the cabling.
🌡️ Silent passive dissipation
The extruded aluminium body of the SpectraB.2.G X45 bars dissipates heat naturally, without any fan. The result: zero noise, zero hotspots and zero dust — a longer LED life in the grow room.
⚡ High photon efficacy
BloomLED-selected LEDs deliver high-end μmol/J efficiency, more useful photons per watt consumed. Even with six bars running, your electricity bill stays under control.
🇫🇷 Designed & assembled in France
Assembly, photometric testing and quality control all take place in France at BloomLED. French-speaking technical support, responsive RMA and available spare parts: long-term peace of mind.
The ideal pack to move from point lighting to a full professional indoor install. With 6 SpectraB.2.G X45 60cm LED grow bars you get the power and uniformity needed for a dense flowering canopy — without compromising on energy efficiency.
In flower mode, the 6 SpectraB.2.G X45 60cm LED bars comfortably cover an 80×240 cm canopy with uniform PPFD. In veg (lower PPF demand), you can stretch up to 100×280 cm. For smaller tents, look at our Pack 5× SpectraB.2.G X45.
Is the spectrum suited to every phase (cutting, veg, flower)?Yes. The full-spectrum SpectraB.2.G recipe blends 3000 K white LEDs with 660 nm deep-red diodes to cover the whole cycle. For cuttings or young seedlings just dim the bars through your controller/timer. For flowering, push all six bars to full power to maximise PAR.
How do the 6 bars connect together?Each SpectraB.2.G X45 60cm bar has inline jack connectors for daisy-chaining. Connect the first bar to the EU 230 V socket and each next bar to the previous one using the short bridge cable included. One wall socket powers all six bars.
Does this pack draw a lot of electricity?Total wattage is around 270 W (45 W per bar × 6). That is comparable to — or lower than — a 250 W HPS while producing more useful photons per watt. On a 12/12 flowering cycle, expect around 3.24 kWh per day.
Can I start smaller and add bars later, or do I need all 6 now?SpectraB.2.G X45 60cm bars are modular. You can start with a smaller kit such as the Pack 3× SpectraB.2.G X45 and add bars later. For a full grow-room project, also check the SpectraMODULE X135 x8 grow-room pack.

Why growers pick the SpectraB.2.G X45 60cm V2
🌱 True full-spectrum veg to bloom
A tuned blend of Samsung LM301H and CREE diodes covers all essential wavelengths: blue for compact vegetative growth, deep red for dense flowering and a balanced white backbone that drives efficient photosynthesis. One bar, full cycle, from seedling to harvest.
⚡ Industry-leading PAR per watt
The Samsung LM301H is the reference chip for indoor horticulture. Paired with BloomLED's premium driver electronics, it delivers one of the best usable-PAR-per-watt ratios on the market. Lower electricity bills, tighter internodes and heavier yields.
🎚️ Pro-grade 0-10V dimming
Native 0-10V control lets the bar plug straight into a commercial light controller or an advanced grower setup. Ideal to ramp up gently on clones, to dial in PPFD by stage and to de-stress plants at the end of bloom for cleaner finishing.
🔧 Modular bar format
At 60 cm × 6 cm with a fully passive aluminum profile, the X45 mounts solo or in pairs / quads to cover 80×80, 100×100 or larger tents with perfectly even light. Fanless design means zero noise, zero moving parts and a longer service life.
🇫🇷 Designed in France by BloomLED
The electronic design, component selection and field validation are all handled by BloomLED, a French growshop specialized in horticultural LED lighting for over 10 years. Full documentation, expert support and a 2-year manufacturer warranty come as standard.
Frequently asked questions
A single bar effectively covers 80 cm × 40 cm in intensive flowering and up to 1 m × 50 cm during vegetative growth when PPFD requirements are lower. For a 80×80 or 100×100 tent, combine 2 to 4 bars for perfectly uniform coverage and maximum yield potential.
Is the spectrum usable for the full grow cycle?Yes. The full-spectrum output from Samsung LM301H plus CREE diodes is engineered to cover the entire plant lifecycle, from cloning to harvest. You don't need to switch lamps between veg and bloom — one bar handles the whole cycle from start to finish.
How does the 0-10V dimming work?0-10V is the professional standard for horticultural and architectural lighting. It needs a dedicated 0-10V controller or dimmer. Once wired in, it lets you fine-tune light intensity, ramp up gently on seedlings and clones, and modulate output by growth stage for cleaner finishes.
What mounting height works best?Hang the bar at 30 cm above the canopy as a baseline. Drop to 20-25 cm to push photosynthesis in bloom, or raise to 40-50 cm for young seedlings. Always read your plants: pale or bleached leaves mean too close, stretching means too far.
The SpectraB.2.G X45 60cm V2 pairs Samsung LM301H reliability with a flexible bar format and BloomLED engineering — the pro choice for a profitable, sustainable indoor grow.
6 full-spectrum LED grow bars — Uniform horticultural lighting for indoor grows up to 80×240 cm.
