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

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
What area does this 4-bar pack actually cover?
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).
