Product Description

The 84X-PRO LED Grow Light is the most powerful grow light in the world for a 2' x 2' area, with tested PAR output matching that of a 400W HPS! Our refined and Patent-Pending 3rd Generation spectrum features quantum balancing to ensure lightning fast growth rates, record breaking yields, tight internode spacing, super-dense flowers, and fruits so monstrous you'll bring all your outdoor plants indoors!

Spectrum is only half the equation to enormous yields however, because light must be delivered efficiently through plant tissues at high intensities to ensure optimal penetration/absorption. Our Patent Pending X2 lens was developed specifically for this purpose, and is the most powerful optic ever invented for LED Grow Lights. Data proves the X2 lens provides an astonishing 569% higher light intensity compared to the same light without the X2 lens, a feat the competition has been unable to duplicate.

X2™ LED Grow Lights lead the world in performance, quality, and reliability, which has been proven time and again by third-party testing and real-time output data. Thanks to our ever-growing engineering and development team who work continuously throughout the year advancing our technologies, we are proud to say that X2 LED Grow Lights are the most powerful horticultural grow lights in the world. Purchase a 84X-PRO today and experience the pinnacle of growing technology in your indoor garden.

Photosynthetically Active Radiation (PAR)

Learn more about PAR

About PAR: Photosynthetically Active Radiation (PAR) specifies the spectral range from 400nm to 700nm that photosynthetic organisms use to process photosynthesis. Photosynthetic Photon Flux Density (PPFD) measured in micromoles per meter squared per second (µmol/m2/s) quantifies the number of photons (or micromoles) in PAR that are available for plants to conduct photosynthesis.

Felicito a quienes lo han desarrollado. He obtenido excelentes resultados. Además, los chicos de post.-venta lo hacen muy bien. Tuve que recurrir a ellos por luces de repuesto. Me las enviaron a Chile cuando estaba a punto de terminar la garantía, y ni siquiera me cobraron el envío. Vaya amabilidad. Estos muchachos sí que trabajan bien. Ahora estoy esperando más luces de repuestos (no duran para siempre) y estoy convencido de que llegarán, y aun buen precio. :) Saludos y gracias por el excelente producto

But a noisy fan. It would be nice with a more quiet one. There is good fans with high effect and low noise level out there (-: Cheers.

Hi Cammie. I'm SO IMPRESSED with the 84 X2Pro that I've just ordered a 21X2 Pro. Thanks so much. Your lights are incredible!

Hi, just writing to let you know how impressed I am with your lights, INCREDABLE!!! They are so bright (can't wait to try the X2 Pros). I bought 2 84X Pros and am doing a continous harvest so I'm not sure how to calculate GPW, but I will say the flower density is way better than my 400w HPS.Shorter internodes,alot less heat, very healthy, and fast growth. Did I mention denser? Wish I had more coverage, maybe the new lens will help. Thanks hydrogrow for a great product! mike

I have had my 2 lights up and running for 2 months now. My electric bill is less this year for those two months than last years when I had no lights running.Plants are full and densely leafed.Heat in grow room is not a problem. And when one side of my light quit working, one phone call and 4 days later I had the parts and the light back up and running.That is saying a lot considering where I live. I am very happy with my lights and plan to buy at least one more this year

My partner and I have been using 4 LED Penetrator Pros (white casing) for a year now and are now ordering 4 more of the 84X2-PROs (silver casing). I've found that vegging fast and thick and flowering is vigorous, lush, and so much larger. We also like Hydro Grow's prices, and warranty. I feel that the company has made alot of improvments in their products and customer service, and the website offers so much more info on products and product development as compared to the other guys. Whenever we needed their help we've been able to talk with a "Live" person who speaks English and results have always been positive . Hydro Grow LEDs offerings are always improving as this lighting technology advances. Thank you Hydro Grow....we will be in touch soon! AL
