Many growers add LED bars as an easy way to expand their lighting footprint or change up their light spectrum. LED Bars are a single row of diodes that come in different spectrums.
You typically wouldn't use an LED bar to grow a plant from seed to harvest. Instead, think of these as supplemental lighting to a main light source (maybe HID).
The MARS HYDRO FC8000 SAMSUNG LM301B LED Grow Light and ECO Farm G3 MARS 800W Samsung LM301B LED Grow Light are both great lighting options for your grow room and here we are breaking down the details for you.MARS HYDRO FC8000 SAMSUNG LM301B LED Grow Light 
Top-Notch LED Diodes: FC8000 mounts 2968 pcs Samsung LM301B & Osram 660nm diodes. Make use of more than twice as many LEDs as comparable lights to drive the grow lights with a low current to stay away from overdrive. Quality guaranteed and high efficiency up to 2.9 μmol/j.
Professional Spectra For Plant Production: Enhanced blue and red light as a specific spectral combination, boosting plant growth while improving the year-round yield and product quality.
Consistent PAR Distribution and Uniform PPFD Output: Multi-light bar style and dense layout of light diodes enable FC8000 LED grow light to have PPFD values in the range of 1000-1500 μmol/m²/s throughout the effective coverage area, the optimal range for cultivation with added CO2.
Daisy-chain Dimming Function: The dimming function is available for 0-100% variable brightness, adapts to different plant growth stages. Max 30 lights can be daisy-chained together and be controlled by one master light.
Commercial LED Grow Light: Wave-shaped heat sink increases the heat dissipation area to achieve superior cooling. Detachable design, easier for installation and store.
