6 reasons to choose this 4-bar LED pack
🌱 Full spectrum optimised for growth & bloom
Samsung LM301B and Osram Oslon 660nm diodes deliver a continuous spectrum from 380 to 780 nm. Your plants move from vegetation to flowering without swapping bulbs. Photosynthesis peaks, stretch stays under control.
💡 Outstanding light uniformity
Four bars spread across 80×160 cm deliver a homogeneous PPFD right to the corners of your tent. Plants grow straight, tight, productive — no more stretching toward the light. Field-tested uniformity within ±5%.
🔧 Dimmable 0–10V Meanwell driver
Set power from 10% to 100% without losing spectrum. Cutting/veg/bloom phases (30/70/100%) are managed directly — no external controller needed. Meanwell HLG driver: industrial reliability rated for 50,000 hours.
🌡️ Controlled heat, no wasted radiator
Heat dissipates along each bar through an extruded aluminium heat-sink. Leaf temperature stays within 2°C of ambient, even at full power. You won't need to oversize your extraction fan.
🔌 Plug & Play — 10-minute install
Daisy-chain cables, YOYO hangers, pre-mounted driver: unbox, hang, plug in. No soldering, no complex wiring. Friendly even on a first setup.
🇫🇷 Engineered in France by BloomLED
BloomLED has been designing, testing and assembling LED grow bars in France for 10+ years. Reactive after-sales support, 3-year warranty, single point of contact for technical questions.
Choose this pack when your tent is 80×160 cm (or two 80×80 tents), you want a single spectrum for the whole cycle and you'd rather skip noisy, hot HPS. The 4-bar pack is the sweet spot between pack 3 (a little light for 160 cm) and pack 5 (oversized for a single tent).
Frequently asked questions
Recommended coverage is 80×160 cm in flowering (1.28 m²) for an average PPFD of 700–850 µmol/m²/s at 30 cm above the canopy. In vegetation you can stretch to 100×180 cm without sacrificing quality. Beyond that, uniformity drops.
Are the power supply and cables included?Yes. The pack ships with the 4 SpectraB.2.G X45 60cm bars, dimmable Meanwell driver, daisy-chain cables, adjustable YOYO hangers and a French/English manual. Nothing extra to buy to start growing.
Can I dim each bar independently?No — the 4 bars are driven by a single 0–10V driver to guarantee spectral and thermal uniformity. If you need independent dimmable zones, look at our multi-driver packs or contact support for a custom quote.
What is the total power draw?At full power the 4 bars pull around 600 W with an efficacy of 2.7 µmol/J. In standard flowering at 80%, expect ~480 W and a manageable bill — versus an equivalent 600 W HPS, you save up to 30% on electricity while producing more.
Is it beginner-friendly?Absolutely. Unbox, hang at the recommended 30–40 cm above the canopy, plug in. Our support team is reachable by email or phone, and the manual covers the 3 most common use cases (small tent, home-grow tent, double closet).

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.
