🌈 Full 380-780 nm spectrum
Samsung LM301B diodes cover the complete photosynthetic spectrum, while Osram Oslon 660 nm diodes boost flowering via the Emerson effect. A light output that closely mirrors sunlight to drive photosynthesis from cloning to harvest, with no compromise on color rendering.
⚡ 2.7 µmol/J PAR efficacy
Roughly 600 µmol/s cumulative output from only 225 W input makes this pack one of the best PAR-per-watt performers on the market. You save up to 40% on electricity compared with a 400 W HPS or equivalent CMH, while also eliminating excess heat from your grow space.
🎚️ 0-100% dimmable
Each bar includes a built-in dimmer to fine-tune intensity: 20% for clones, 50-60% for veg, 100% for full flower. Dial in your DLI to the µmol and prevent light stress during the first days after transplant or cloning.
🛡️ IP65 humidity protection
All five bars are IP65 certified, fully protected against water splashes and the 60-70% RH humidity typical of a flowering tent. Built for real-world grow conditions — no corrosion, no premature driver failure.
🔗 Plug & Play daisy-chain
The pack ships with all power and daisy-chain cables plus adjustable hanging hooks. Plug the first bar into a 230 V EU outlet, chain the other four — full installation in under 20 minutes, no tools or advanced electrical skills required.
🇫🇷 Designed in France by BloomLED
BloomLED has been developing and testing SpectraB.2.G bars in France for over 10 years. Each pack is assembled, PPFD-tested and individually validated before shipping from our European warehouse. European customer support, 3-year warranty, spare parts available.
Yes, that's the target footprint. In flower, all five SpectraB.2.G X45 60cm bars deliver a consistent PPFD of approximately 700-750 µmol/m²/s at 30 cm from the canopy — the optimal target for an 80 × 200 cm tent. In veg or cloning, the same layout can cover up to 100 × 220 cm when dimmed to 50-60%.
Can I wire the 5 bars in parallel or must I daisy-chain them?Both configurations work. Daisy-chaining (with the cables provided) lets you use a single 230 V EU outlet, which simplifies wiring through a tent. You can also power each bar independently if you need to split the space into multiple zones or run drivers from separate outlets.
Is the spectrum suitable for all phases (cloning, veg, flower)?Yes. The 380-780 nm spectrum covers the critical wavelengths: 450 nm (vegetative growth), 660 nm (flowering and Emerson effect), moderate UV-A and far-red to densify buds and promote trichome production. A proven full-cycle spectrum that saves you from swapping lamps between phases.
What hanging height and intensity should I use per phase?In cloning and young plants: hang at 40-50 cm above the canopy, dim to 20-30%. In veg: drop to 30-40 cm with the dimmer at 50-60%. In flower: 20-30 cm at 100%. The built-in dimmer prevents any light stress, particularly during the first week after transplanting.
What timer and power do I need with this pack?A standard 230 V EU outlet is enough for the whole daisy-chained pack. Plug the main line into a mechanical or digital timer: 18/6 for veg, 12/12 for flower. For a longer build, add a Pack SpectraB.2.G X45 60cm ×2 for a dedicated cloning area, each driven by its own timer.
A pack engineered for growers aiming at professional yields: the modularity of five independent bars, the reliability of a Samsung + Osram pro spectrum, and the efficiency of French BloomLED engineering. Go from amateur setup to high-end install in a single order.

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.
