Why choose this 3-bar BloomLED kit?

🌱 Optimised full spectrum

Blend of 3500 K white LEDs and 660 nm deep reds to drive photosynthesis, flowering and trichome production. The red-to-white ratio is calibrated by our engineers to maximise yield per watt and support vigorous growth from week one. Run tomatoes, herbs, flowers or fruit on the same bars, from seedling to harvest.

⚡ Premium energy efficiency

High μmol/J output thanks to Samsung LM301B diodes, the world reference. You pull fewer watts while delivering an even PPFD across the canopy — no dark zones. The result: tighter electricity bills and healthier plants throughout the cycle.

🔌 Instant Plug & Play setup

Simple wiring: daisy-chain the 3 bars using the supplied cables, plug the EU 230 V connector in, and your lighting is running in under 5 minutes. No ballast, no external driver to install. Ideal for beginners and perfect for experienced growers who want to save time.

🌡️ Silent passive cooling

High-density extruded aluminium heatsink, no fan, fully silent. The LEDs stay cool for > 50,000 hours of lifespan without flux loss (L80). Perfect for living spaces where fan noise would be intrusive, or for noise-sensitive rooms.

📐 Full modularity

Lay out a 3×1 grid, 2+1 or comb pattern to match your tent. Works in 60×60, 80×80, 80×120 and 100×100 cm tents, perfect for compact grow rooms or vertical multi-tier setups. Bars mount easily on the included adjustable hangers.

🇫🇷 Designed in France by BloomLED

Engineered and tested by the BloomLED team, horticultural lighting experts for over 10 years. Lab-validated spectrum, strict QC and technical support based in France. You get personal advice and a full spare-parts catalogue.

Frequently asked questions

What area does this 3-bar kit cover?

This kit comfortably lights 80 × 120 cm through the full cycle (veg + flower). In a 100 × 100 cm tent you'll get extra intensity, ideal for light-hungry strains like heavy autoflowers. For a 120 × 120 cm tent we recommend the 4-bar pack to avoid softer edges.

Is the kit suitable for flowering?

Yes. The full spectrum embeds 660 nm deep reds that trigger and sustain flowering (Emerson effect) while keeping enough blue to maintain a compact structure. Veg and flower happen on the same kit, simplifying your workflow and cutting equipment costs.

Can I add more bars later?

Absolutely. SpectraB.2.G bars are daisy-chainable. Step up to a 4, 5 or 6-bar kit later without rewiring — simply link a new bar in series through the output connector. It's the most flexible way to scale your grow over time.

What distance between bars and canopy?

We recommend 20 to 40 cm between the bars and the top of the plants depending on stage: closer in veg (20–25 cm) to tighten internodes, higher in late flower (30–40 cm) to avoid light stress and let the tops finish smoothly. Check canopy temperature to fine-tune.

What warranty does the kit come with?

2-year manufacturer warranty covering every bar and cable supplied. Technical support and after-sales based in France, spare parts in stock (drivers, daisy-chain cables, hangers). Our team replies within 24 business hours.

Scaling up and usage tips for growers

Whether you're running a single 80 × 120 cm tent or starting a rolling production with several bays, the SpectraB.2.G X45 platform grows with you. The 3-bar kit is the sweet spot for a focused canopy: spread the bars evenly across the long axis of your tent, keep a 20–40 cm distance from the tops, and dim your timers down by 1 hour per week during the final ripening stage to push trichome density. The daisy-chain design lets you add bars as your experience and space increase — without changing fixture, driver or wiring logic. That consistency is exactly what BloomLED ships: a platform, not a one-off lamp.

The kit built by growers for growers: tuned spectrum, hassle-free install, yields that deliver. Your grow tent steps confidently up to the next level with a scalable, silent and warranted solution.

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

How much canopy can one SpectraB.2.G X45 60cm V2 cover?

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.
