Most grow lights force you to choose between coverage and even light distribution - wider footprint usually means more dark zones between bars. This 1100W wide bar LED grow light solves that by rethinking the bar itself: instead of a narrow strip, each bar spans 12cm wide, six bars total, covering a full 4×4 ft growing area with light spread evenly across the whole canopy, not just directly under each bar.
Products Features
Each bar spans roughly 12cm wide - an extra-wide format that spreads light across a broader footprint, giving more even coverage than standard narrow-bar fixtures.
Built with large-chip LEDs, and the UV diodes use quartz crystal encapsulation for stable, high-efficacy output.
Supports 2-channel dimming, letting growers adjust the spectrum to match every stage of the growth cycle.
A thickened aluminum heat sink delivers strong light output while keeping energy consumption efficient.

Why Wide Bar Design Matters
Standard narrow bars concentrate diodes in a thin strip, leaving stripes of stronger and weaker light across the canopy. This 1100W wide bar LED grow light takes a different approach, spreading diodes across a wider bar for a more balanced result:
More even coverage
Light spreads across a broader surface, reducing the dark zones that typically show up between narrow bars.
more chips per bar
The wider format helps support higher PPFD output without concentrating heat in one narrow strip.
Larger surface for heat to dissipate
Supports the fanless, passive cooling design at this power level.
Fewer fixtures per room
One wide-format unit covers more ground, simplifying wiring for growers running multiple LED grow lights for indoor plants across a commercial space.
For growers prioritizing consistency across large canopies, this design trades a narrow, concentrated beam for broader, more balanced coverage.
Products Details
Applications
This wide bar LED grow light is built for commercial indoor plant, particularly for high-light-demand crops that benefit from a strong UV/IR presence during flowering. The even light distribution and independent spectrum control make it well suited for growers running multi-stage cultivation cycles at scale.
Trusted by Commercial Growers Worldwide
Our LED grow lights are already lighting up commercial greenhouses and indoor grow rooms across the United States, Thailand, Canada, Australia, and Europe. As a full-scale manufacturer, we support complete project specifications and customization, tailoring fixture layout and spectrum to each grow room's actual requirements - backed by complete qualification documentation for facility compliance.
FAQ
Q: How much space does a 1100W wide bar LED grow light cover?
A: This grow light covers approximately 4×4 ft, making it suited for a single commercial grow room zone or one section of a larger multi-fixture layout.
Q: Is passive cooling enough for a 1100W fixture?
A: Yes. The wide bar format spreads heat across a larger surface area, letting the aluminum heat sink manage this power level without a fan - no moving parts to maintain.
Q: Can this light be used for the full growth cycle, not just flowering?
A: Yes. With independent UV/IR dimming separate from the main spectrum, growers can adjust the light recipe for vegetative growth, flowering, and everything in between.
Q: Does this grow light work with standard power outlets outside the US?
A: Yes. The AC110-277V input range covers standard voltages across North America, Europe, and most global power grids without needing a separate transformer.
