Precision lens optics. Powerful output. Easier grow-room maintenance. The iMOORELED 1350W 4×6 LED grow light brings together eight light bars and integrated 105° lenses to deliver light across the canopy. With 3,920.8 µmol/s PPF and an average 1,452 µmol/m²/s PPFD at 60 cm , up to 2.9 µmol/J PPE , and independent full-spectrum, far-red and UVA control, it is built to make every square foot of your indoor cultivation area work harder.
Why choose a lens-based LED grow light?
Guide more usable light toward the plants
The 105° lenses are a secondary optical system, not just a cover. They shape light from the LEDs and direct it toward the 4×6 ft cultivation area. Paired with eight spaced light bars, the optics help improve canopy PPFD distribution and limit wasted spill toward walls and aisles.
Give the LEDs a dedicated protective layer
Each lens forms a physical barrier over the LED emitters, reducing direct contact with the LEDs and their exposure to grow-room dust and residue. Compared with a basic protective coating alone, the lens adds purposeful light control as well as a more robust surface over the emitters.
Keep optics clear between growing cycles
The accessible lens surfaces can be wiped clean during routine maintenance. Removing buildup from the optical surface helps keep the light path clear and makes crop turnover more convenient for your team.
Commercial power with flexible spectrum control
1350 W power · 3,920.8 µmol/s PPF · up to 2.9 µmol/J PPE. Run the full-spectrum channel for your core lighting program and adjust the separate 730 nm far-red and UVA channels to suit your cultivation strategy.
RS485 digital dimming for confident grow-room control
Bring multiple fixtures into one coordinated lighting setup with RS485 digital dimming . Its differential communication helps resist electrical interference on control wiring, while digital commands support consistent, repeatable dimming across a commercial installation. With the matching iMOORELED controller, available on request , growers can adjust the full-spectrum, far-red and UVA channels independently to match their lighting program. This is a valuable upgrade for growers moving beyond basic 0–10 V analog dimming.
Engineered to manage heat, built for long-term reliability
High-quality LED emitters are operated below their maximum power rating to reduce heat concentration at the light source. A thermally conductive PCB transfers heat into substantial 6063 aluminum heat sinks. Each light bar has a 90 mm wide aluminum heat sink using approximately 1 kg of aluminum per meter , providing generous surface area for passive cooling. A branded driver completes the robust electrical design. Together, these choices support stable operation through demanding grow-room schedules, backed by a 5-year limited warranty .
Built to fit your workflow
The foldable eight-bar frame and centrally mounted driver arrive ready for installation. Start with the fixture 60 cm (about 24 in) above the canopy , the reference height for its 4×6 ft PPFD layout. For projects with higher mounting positions, adjust fixture spacing, mounting height and dimming to reach the crop's target light level. A rated lifetime over 50,000 hours and a 5-year limited warranty support demanding commercial growing schedules.

Applications
Ideal for commercial indoor grow rooms, flowering rooms and other controlled-environment horticulture projects. The 4×6 ft flowering coverage area, lens-based optical design and adjustable channels make it a strong choice for growers who want powerful top lighting and practical maintenance.
Frequently asked questions
What are the fixture dimensions?
The fixture is 69.13 in (1756 mm) long and 42.6 in (1082 mm) wide. It is designed for a 4×6 ft flowering area.
How high should I hang the 1350W top light?
Start at 60 cm (about 24 in) above the canopy, the height used for the fixture's 4×6 ft PPFD reference. If your installation calls for a higher position, adjust mounting height and RS485 dimming to reach your preferred canopy PPFD as the crop develops.
What are the benefits of lens optics?
The lenses serve three purposes: they steer light toward the cultivation area, provide a physical barrier over the LEDs, and create accessible surfaces for routine cleaning. Together with the eight-bar layout, the 105° optics help distribute PPFD across the 4×6 ft canopy.
Why choose lenses instead of a glue-coated LED surface?
A basic coating primarily protects the emitter. A purpose-designed secondary lens also controls where the light goes. It can direct more usable light toward the canopy instead of surrounding walls and aisles, while providing a defined surface that can be wiped clean between crops.
How do different light colors affect cannabis cultivation?
Blue light contributes to plant shape and can help growers manage compact vegetative growth. Red light is a major photosynthetic input that supports biomass production. Green light , present in broad white light, contributes to photosynthesis and reaches deeper into a dense canopy. These wavelengths work together in the fixture's full-spectrum channel.
730 nm far-red affects plant architecture and light-response signaling; its separate channel allows growers to adjust it for their crop schedule. UVA provides another independently controlled supplemental channel for cultivar-specific lighting strategies. Responses to UVA and far-red depend on variety, intensity and timing, so growers can fine-tune the recipe for their own production goals.
Can blue and red be dimmed separately?
Blue and red are part of the full-spectrum channel. The three independently controlled channels are full spectrum, 730 nm far-red and UVA.
How does the 1350W grow light manage heat?
Its LEDs are operated below their maximum power rating. Heat moves through a thermally conductive PCB into eight substantial 6063 aluminum heat sinks, each 90 mm wide with approximately 1 kg of aluminum per meter. This passive-cooling design is paired with a branded driver and a 5-year limited warranty.
Can I control the three channels separately?
Yes. The full-spectrum, 730 nm far-red and UVA channels can be controlled separately through RS485 using the matching iMOORELED controller.
Is the RS485 controller supplied with the light?
The matching iMOORELED controller is available on request. Tell us how many fixtures and grow rooms you plan to control, and we can include the suitable controller in your quotation.
What is the advantage of RS485 digital dimming over 0–10 V?
0–10 V uses an analog voltage to set the dimming level. RS485 carries digital control commands over a differential signal that is well suited to electrically noisy, multi-fixture installations. For growers, this means more robust communication, consistent dimming instructions and convenient centralized control of the fixture's three spectrum channels using the optional iMOORELED controller.
