If you're running large flowering room and your current LED grow light is leaving the corners underlit while the center hot-spots, that's a coverage problem, not a wattage problem. This 4x6ft LED grow light is built specifically for that footprint - a trifold frame with 9.5cm wide bars, available at 1000W or 1200W, so you can match output to how aggressively you're pushing PPFD in your room.
Features and Advantages
This full spectrum 4x6ft LED grow light weights its diode ratio toward flowering. A 60mil large red chip drives bud formation, while UV and IR run on an independent dimming channel, low during veg, raised in late flower to support trichome production. The white channel, a custom large chip benchmarked against 281BVK, holds PAR output without diluting your flowering red-to-blue ratio.

Build Quality for Continuous Commercial Operation

Built for rooms running fixed schedules for months. Cooling is fully passive through a thickened aluminum alloy heat sink, no fans to fail. Rated IP65, L90 50,000 hours, 3-5year warranty, covering most greenhouse and indoor flowering rooms without derating.Every fixture ships from our Guangdong LED grow light manufacturer facility, built for growers who need consistent output across dozens of units.
Multiple fixtures run off one controller via RJ12/RJ45 chaining - DIM OUT connects to the first fixture's INLET, and units chain from there, with CH1 for single-channel control. Each fixture's knob is set to cascade (100%) so the master controller has full authority. UV should stay off during seedling and early growth, reserved for flowering and fruiting, and kept under 2 hours a day even in bloom.

Golden exterior design

A distinct gold finish sets this line apart at a glance from standard black or silver fixtures - signaling its position as our flagship model built specifically for the flowering stage. For growers who run multiple lines side by side, it also doubles as a quick visual cue on the floor: gold means this fixture is the flowering-stage unit, so it's easy to spot at a glance during setup or a walkthrough without checking model labels.
Coverage and Output for Large Flowering Rooms
We tested the 1200W LED grow light across a 1.1 x 1.8m canopy area (roughly a 4x6ft footprint) at four hang heights, taking a full measurement grid at each height rather than a single center-point reading. Here's what the data actually shows:
|
Hang Height |
Average PPFD |
Minimum PPFD |
Maximum PPFD |
|
30cm |
1345 μmol/m²/s |
858 μmol/m²/s |
1683 μmol/m²/s |
|
40cm |
1231 μmol/m²/s |
792 μmol/m²/s |
1531 μmol/m²/s |
|
50cm |
1122 μmol/m²/s |
733 μmol/m²/s |
1408 μmol/m²/s |
|
60cm |
1072 μmol/m²/s |
755 μmol/m²/s |
1298 μmol/m²/s |
A few things worth pointing out in this data instead of just the averages: the spread between minimum and maximum narrows as hang height increases - at 30cm the swing is over 800 μmol/m²/s edge to center, but by 60cm that gap tightens to under 550 μmol/m²/s. That's the practical tradeoff of hanging closer versus higher: closer gets you more peak intensity, but higher gets you more even canopy coverage. For most commercial flowering rooms running this footprint, a 40-50cm hang height is the practical middle ground - average PPFD still sits above 1100 μmol/m²/s while the edge-to-center variance stays manageable without extra edge fixtures.

FAQ
Q: Should I choose the 1000W or the 1200W LED grow light?
A: Both run the same efficacy. Choose the 1200W if you're pushing higher DLI targets, running supplemental CO2, or want more headroom before you'd need a second fixture. The 1000W is enough for most standard flowering programs on this footprint.
Q: Can I run this in a greenhouse with high ambient temperatures?
A: Yes, up to 104°F/40°C ambient. Above that, output should be de-rated or supplemental cooling should be added to the room.
Q: What makes this light different from a standard full spectrum LED grow light?
A: Custom large chips + independent UV/IR dimming - better flowering performance than a standard full spectrum light, not just a wider bar or different finish.
Q: Do you offer OEM or private label for bulk orders?
A: Yes, OEM and ODM support is available at the factory level, including custom spectrum tuning and private branding for distributors and commercial buyers.
