🌈 Full spectrum 380-780 nm

Samsung LM301B diodes cover the entire photosynthetic range while Osram Oslon 660 nm diodes boost flowering. The pack mimics natural sunlight to drive photosynthesis at every cultivation stage.

⚡ 2.7 µmol/J efficacy

Nearly 240 µmol/s for only 90 W consumed — one of the best PAR efficiencies on the market, saving meaningful energy versus HPS or CMH setups.

🎚️ Dimmable 0-100%

A built-in dimmer lets you fine-tune intensity at every stage: 20% for clones, 60% for veg, 100% for flower. Dial in your DLI with µmol precision.

🛡️ IP65 moisture resistance

IP65-certified bars shrug off splashes and the humidity of a real grow tent. Built to survive the conditions of genuine indoor horticulture.

🔗 Daisy-chain ready

Power cables and daisy-chain connectors included. Mounting brackets and adjustable rope hangers in the box — installation done in under 10 minutes.

🇫🇷 Designed in France

BloomLED has been engineering SpectraB.2.G bars in France for over a decade. Every pack is tested and validated before shipping from our EU warehouse.

Is this 2-bar pack enough for a 60×60 cm grow tent?

Yes — that's the recommended format. In flower, both SpectraB.2.G X45 60cm bars deliver around 650-700 µmol/m²/s PPFD at 30 cm from canopy, hitting the sweet spot for a 60×60 tent. For an 80×80 cm tent in veg or cloning, the pack also performs well.

Can I start with one bar and add the second later?

Absolutely. Each bar has its own driver and can be powered independently. Begin with a single bar during cloning or veg, then bring in the second one for flowering to maximize yield.

Does this spectrum suit every phase (clone, veg, flower)?

Yes. The full 380-780 nm spectrum includes all critical wavelengths: 450 nm (veg), 660 nm (flower, Emerson effect), moderate UV-A and far-red to tighten buds. It's a true full-cycle spectrum.

How high should I hang the bars above the canopy?

Clones / seedlings: 40-50 cm at 30%. Veg: 30-40 cm at 60%. Flower: 20-30 cm at 100%. The dimmer prevents light stress in the first days after transplant.

What timer and power setup works with this pack?

A standard 230 V EU socket is all you need. Plug both bars into a mechanical or digital timer (18/6 for veg, 12/12 for flower). Pair with a E27 cable with switch if you add supplementary bulbs.

A pack built for growers ready to level up: the modularity of two bars, the reliability of a pro spectrum, the efficiency of French BloomLED engineering. Never settle between power and efficacy again.

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.
