800W - 1000W LED Grow Lights: Complete Guide
Fixtures drawing 800 to 1000 watts at the wall are designed for growers who need maximum canopy coverage and harvest consistency. At this power level, modern LED bar arrays from Grower's Choice, HLG, AC Infinity, Aelius LED, and Secret Lighting cover 5x5 canopies at peak flower PPFD targets of 1000 to 1500 micromol per square metre per second. Many models now hit 2.8 to 3.1+ umol/J, matching or surpassing double-ended HPS efficiency while running at far lower temperatures.
The Grower's Choice ROI-E720 and AC Infinity Ionframe EVO8 are well-proven in this class, offering deep canopy penetration and consistent uniformity across the full 5x5 footprint. For growers prioritizing raw efficiency, the Aelius REDD 800 introduces a far-red enhanced spectrum shown to accelerate the Emerson effect and compress finishing times. The Secret Lighting SL-830 adds UV and IR on a single driver for growers targeting terpene and resin production.
Most fixtures in this wattage tier are rated for 240V operation. Running at 240V reduces current draw by half compared to 120V, which means less line loss, cooler plugs and cords, and room to run multiple lights on a single circuit. If you are setting up a multi-light room, a licensed electrician can install 240V circuits and proper load balancing before you hang your first fixture.

Frequently Asked Questions
What canopy size do 800W to 1000W LEDs cover?
Most 800 to 1000W fixtures are rated for a 5x5 canopy at full bloom PPFD. Pushed to higher intensity, some can serve a 4x4 with PPFD above 1200 umol/m2/s, which suits CO2-supplemented grows. Dialed back to 60 to 70% output, a 1000W fixture can cover a 4x8 canopy at moderate intensity for multi-strain grows.
Do 800W to 1000W LEDs need 240V power in Canada?
They do not strictly require it, but most manufacturers recommend 240V for fixtures above 700W. Running at 240V halves the amperage draw, which reduces heat in cables, prevents tripped breakers, and is more efficient over longer wire runs. A 1000W fixture on 120V draws about 8.5 amps, which is possible on a 15A circuit but leaves little headroom for other devices.
How does far-red spectrum benefit 800 to 1000W grows?
Far-red wavelengths (700 to 800nm) trigger the Emerson enhancement effect, where plants absorb more energy when far-red and red photons arrive together. At high PPFD levels typical of 800 to 1000W fixtures, adding far-red can shorten the dark period needed to trigger flowering and improve light use efficiency in the lower canopy. Models like the Aelius REDD 800 integrate far-red diodes directly into the fixture.
Can I use a single 1000W LED for multiple plants in Canada?
Yes. A single 1000W bar light covers 5x5 feet, which accommodates 4 to 9 plants depending on your training method and container size. Sea-of-green setups typically fit more plants per square foot, while larger individual plants in a SCROG net may fill the same footprint with fewer plants.
What is the monthly operating cost of a 1000W LED in Canada?
At a 12-hour flower photoperiod and an average Canadian electricity rate of $0.14 per kWh, a 1000W fixture costs approximately $50 to $60 per month. High-efficiency models that produce the same PPFD at 900W rather than 1000W reduce that by 10% over a full cycle.
How do I select between 800W and 1000W for my space?
If your canopy is a standard 5x5, an 800 to 850W fixture run at 100% typically hits the right PPFD range. A 1000W fixture in the same space allows you to dial back to 80% during early flower and ramp up during peak bloom, giving you more control over light stress. If you are running CO2 supplementation above 1000 ppm, the 1000W option gives you ceiling to reach the higher PPFD those plants can use.
Do 800W to 1000W LED lights ship free to Canada?
Yes. All fixtures in this range ship free to Canadian addresses through Trimleaf Canada. Most orders arrive within 3 to 7 business days.
