Slim profile full spectrum, including far red, ideal for vertical racks and commercial multi-tier grow rooms.

The Ultra800 LED Grow Light is built for vertical cultivation systems where space efficiency and airflow are critical. Drawing 800W with a PPF of 2080 µmol/s and an efficacy of 2.6 µmol/J, this full-spectrum grow light, including Far Red, drives healthy plant growth from seedling through flowering. Its slim, flat design maximizes usable vertical space, making it a top choice for multi-tier grow rooms and stacked hydroponic setups.

With passive cooling, foldable construction, and compatibility with TrolMaster controllers via LMA-14 adapter, the Ultra800 makes installation and automation simple. Certified by ETL, DLC, CE, and FCC, and backed by a 5-year warranty, it delivers dependable, high-performance lighting while qualifying for energy rebate programs.

Currently only available for 208-277V

Is the Ultra800 energy-efficient?

Yes. With an efficacy of 2.6 µmol/J, the Ultra800 is far more efficient than HPS lights. For comparison, older HPS average 1.3 µmol/J, standard DE HPS reach 1.7 µmol/J, and premium units peak at 2.1 µmol/J. The Ultra800 produces more usable light per watt, saving up to 30% in electricity while delivering higher yields and healthier plants in demanding indoor environments.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.

Does GrowPros offer energy rebates for its products?

Yes! The potential savings from energy rebates are substantial, often covering approximately 50-75% of the overall project cost. To get a personalized estimate of your potential savings, simply contact us and we'll provide a complimentary assessment tailored to your project.

How much energy can I save with GrowPros' energy-efficient lights?

Upgrading to LEDs can cut your energy use by up to 75% compared to old-school incandescent bulbs and around 40% less than HID lights. That means lower electricity bills, especially if you're running multiple fixtures. Plus, LEDs last way longer, so you’ll save even more on replacements and energy costs over time.

Can GrowPros LED lights be customized for different bud strains?

Absolutely! We offer customizable spectrums and intensities to match the specific needs of different strains. Our tailored lighting solutions help optimize growth, potency, and terpene profiles.
