Photometric Performance and Energy Efficiency
Benefit from a photonic efficiency of 2.3 µmol/J and a flux of 96 µmol/s : the LED horticultural bar is ahead of older HPS/CMH technologies.
In indoor growing, its high PPFD ensures dense growth while reducing energy consumption, with up to 55% savings compared to equivalent HPS lamps. Thanks to this remarkable efficiency, controlling annual costs becomes easy: less than €25/year for a 42W bar in intensive vegetative use, or less than €0.02/hour for the 26W version.
Spectrum 6600K and Optimal Vegetative Growth
The HeroLED B uses a 6600K white LED with a spectrum perfectly aligned with the growth phase: its high blue density promotes compact plants, preventing excessive stretching. Covering the 420-480 nm range, this spectrum ensures strong root development and accelerated propagation of cuttings.
In addition, linking several bars allows you to adjust the spectral ratio according to the size of your growing space, offering optimal flexibility for vegetative growth.
Fast Installation and Custom Coverage
Thanks to its compact design, the HeroLED B can be installed horizontally or vertically, even in confined spaces:
- 42W version: 105 cm x 4 cm x 3 cm, weighing only 0.58 kg
You can connect up to 10 bars in series to cover 0.5 to 1.2 m² depending on your needs. Position the lamp between 25 and 35 cm from the plants to achieve ideal PPFD values.
Simplified Control and Automation
Easily control the intensity of the HeroLED B with its dimming options and integrate it with your compatible controllers via potentiometer or segmented timer. Daisy-chain connection simplifies the management of large areas up to 10 bars, optimizing your installation for precise DLI control.
Sustainability and Return on Investment
Designed for durability, the HeroLED B boasts a lifespan exceeding 40,000 hours and comes with a 2-year manufacturer's warranty . It pays for itself in less than 18 months compared to a 100W HPS lamp, while also cutting electricity bills in half.
These advantages, combined with a competitive purchase price, offer clear visibility on annual savings and a measurable return on investment each season.
Profile and Applications
The HeroLED B meets the needs of both amateur and professional growers for sowing, propagation, and vertical farming. It adapts to all tent sizes from 60x60 to 120x120 cm , indoors or in greenhouses.
Ideal for 4 to 30 plants depending on the configuration , it is recommended for propagation and vegetative growth thanks to its growth-oriented spectrum and modular design. A real advantage for those aiming for professional and controlled LED cultivation, without complexity.

Joseph's Council
To get the most out of the HeroLED B, I highly recommend adjusting the installation height according to the density of your seedlings or cuttings. In my experience, I've found that connecting several bars in series ensures remarkable light uniformity across the entire area. My tip: start with one bar to test it, then gradually add more as your needs evolve. This modularity makes all the difference for perfect and even growth. Joseph – Director of GrowLED
