BloomLED SpectraB2G: The Specialized LED Bars That Change Everything
BloomLED SpectraB2G LED bars represent a revolutionary approach to specialized horticultural lighting. Unlike traditional LED panels, these bars focus on ultra-precise spectra – UV-A and infrared – to trigger specific photobiological reactions in your plants. This is exactly what was missing to take indoor cultivation to the next level.
Why choose SpectraB2G bars
The strength of SpectraB2G lies in their extreme specialization. Each bar delivers 30 watts of concentrated power in an ultra-precise spectral band. UV models like the SpectraB.2.G UV60 - 30Watts - Horticultural LED UV A Bar emit in the 365-385nm range to stimulate trichome production and strengthen natural defenses. Frankly, the difference is visible to the naked eye after a few weeks of use.
Infrared bars like the SpectraB.2.G IR60 - 30Watts - Horticultural LED Infrared Bar work at 730nm to trigger the Emerson effect and accelerate cell elongation. This is particularly effective at the beginning of flowering to maximize stretch. 120cm versions like the SpectraB.2.G UV120 - 30Watts - Horticultural LED UV A Bar perfectly cover 120x120cm spaces without any shadow zones.
How to choose your SpectraB2G bar
The choice depends on three criteria: the size of your space, the cultivation stage, and your objectives. For a 60x60cm space, 60cm models are more than sufficient. Beyond that, opt for 120cm versions which ensure homogeneous distribution. The SpectraB.2.G IR120 - 30Watts - Horticultural LED Infrared Bar is perfect for large installations.
In terms of spectrum, UV-A boosts the quality and density of flowers, while infrared accelerates growth and optimizes photosynthesis. The ideal is to combine both: IR during growth and early flowering, UV-A at the end of flowering to maximize resin. These bars are designed to complement your main lighting, not replace it.
Frequently Asked Questions
Which SpectraB.2.G bar should I choose based on the size of my grow space?
For a 60x60cm or 80x80cm space, 60cm models perfectly cover the surface with homogeneous intensity. Beyond 100x100cm, 120cm versions become essential to avoid under-lit areas. Count approximately 0.5 watts per cm² for UV and 0.3 watts per cm² for infrared. A 60cm bar effectively covers 3600cm², while a 120cm can handle up to 14400cm² depending on the installation height.
Can I use a single SpectraB.2.G bar for the entire grow or should I combine it with other lighting?
SpectraB2G bars are specialized complements, not primary lighting. They must absolutely be combined with full spectrum lighting (LED, HPS or CMH) which provides the photons for photosynthesis. UV and infrared represent only 5-10% of the total necessary spectrum. Use them as “boosters”: 2-4h of UV at the end of flowering, 12h of infrared during growth and stretch. This combination is what works wonders.
What is the difference between SpectraB.2.G models (IR, UV) and which one is best for me?
UV models emit in the 365-385nm range to stimulate the production of secondary compounds and strengthen cell structure. The result: more resin, better stress resistance. IR models work at 730nm to trigger photomorphogenic reactions: elongation, stomatal opening, improved photosynthetic efficiency. If you have to choose, infrared offers broader benefits throughout the cycle. UV remains the best for final quality.
How to install and configure the SpectraB.2.G bar to optimize growth and flowering?
Install the bar 30-50cm from the plants depending on the desired intensity. For infrared, turn it on 15 minutes before and after the main lighting to maximize the Emerson effect. UV is best used at the end of flowering: 2h per day for the last 3 weeks, preferably in the middle of the photoperiod. Be careful with your eyes and skin with UV! Use a programmable timer to automate cycles. Color temperature is not critical here; we are looking for pure photonic efficiency.
How long is the warranty and how does after-sales service work?
BloomLED generally offers 2-3 years warranty on its LED bars, covering manufacturing defects and premature diode degradation. The LEDs used are rated L90B10, guaranteeing 90% of the initial flux after 50000h of use. In case of a problem, after-sales service goes through the reseller who handles returns and exchanges. Since the bars are modular, some repairs are possible (drivers, connectors). Keep your invoices and respect the conditions of use to claim the warranty without any hassle.
