Under 200W LED Grow Lights: Complete Guide
Whether you are starting seeds, running a propagation tray, or growing in a 2x2 or 2x4 tent, under-200W LED grow lights give you the photon output you need without drawing a full circuit. Modern quantum-board and bar designs in this range run 50 to 190 watts at the wall and convert electricity to plant-usable light at efficiencies above 2.5 micromol per joule. The result is a cooler, quieter grow space that costs less to run than older blurple panels of the same claimed wattage.
The fixtures stocked here span the full under-200W spectrum. On the compact end, the HLG 65 V2 and AC Infinity Ionboard S22 serve 2x2 footprints for clone stations and propagation. Step up to the AC Infinity Ionboard S24, Mars Hydro TS 1000, or HLG 200 R SPEC for a 2x4 or compact 3x3 canopy. Under-canopy and supplemental bars from Faven Lighting, Aelius LED, and Grower's Choice also fall into this tier, offering red-enhanced or far-red wavelengths to accelerate flowering when paired with a primary fixture above.
Key specs to compare in this wattage range include PPF output (micromol per second), efficiency (micromol per joule), and coverage area at the manufacturer's recommended mounting height. A 100W bar at 2.7 umol/J produces more usable light than a 100W blurple panel at 1.8 umol/J, so look beyond wattage alone when choosing.
All fixtures ship free to Canadian addresses. If you need help sizing a light for your tent or setup, our team can point you to the right model based on your canopy footprint and target PPFD.
Frequently Asked Questions
What can I grow with an under-200W LED?
Under-200W fixtures work well for seedlings, clones, microgreens, herbs, and the vegetative stage in tents up to 2x4 feet. For a full flowering cycle in a 2x4 or 3x3, a 150 to 200W quantum board or bar light delivers adequate PPFD when dialed in correctly.
How does efficiency affect heat in a small grow space?
A 100W fixture running at 2.7 umol/J produces more light and less heat than one running at 1.8 umol/J. In a small tent with limited airflow, choosing a high-efficiency model measurably reduces the cooling load and keeps temperatures stable without an oversized exhaust fan.
Can I run an under-200W LED on a standard Canadian household outlet?
Yes. Fixtures in this range draw well under 2 amps at 120V, which is a small fraction of a standard 15A household circuit. Most growers plug them directly into a wall outlet or a timer without any electrical modifications.
Do these lights include dimming controls?
Most modern fixtures in this range include an onboard dimmer knob. Some, like the AC Infinity Ionboard series, add controller compatibility via 0-10V ports so you can schedule intensity ramps through an environmental controller. Check the individual product page for controller compatibility details.
What is the difference between a full-spectrum panel and an under-canopy bar in this wattage range?
Full-spectrum panels hang above the canopy and serve as the primary light source. Under-canopy bars mount horizontally between plant rows to push light into the lower canopy, boosting yield on lower branches that a top light cannot reach effectively. The two types are complementary rather than interchangeable.
Which brands carry under-200W fixtures suited for propagation?
Horticulture Lighting Group (HLG), AC Infinity, Mars Hydro, Spider Farmer, and Aelius LED all offer models optimized for seedling and propagation use.
Do you ship under-200W LED lights to all Canadian provinces?
Yes. Trimleaf Canada ships to all provinces and territories. Orders typically arrive within 3 to 7 business days depending on destination.
