Our MEIJIU 240W LM281B QUANTUM BOARD indoor horticulture LED grow light is designed to replace a single-ended 600 watt HID. The MEIJIU 240W LM281B QUANTUM BOARD uses 1 of our custom designed full-spectrum high efficiency white light Quantum Boards with Samsung LM281B and Deep Red LED 660nm.
MEIJIU 240W LM281B QUANTUM BOARD produces ultra-high levels of PPFD evenly spread over a 0.6mx1.2m grow area and a full-spectrum grow light producing consistently high quality & high yield indoor crops.
The new line of MEIJIU 240W LM281B QUANTUM BOARD is built using high quality Inventronic drivers and latest generation top bin LEDs from Samsung and Epistar, generating a full-spectrum light source ideal for veg and flowering cycles.
New improved longer design for more even light coverage
High efficiency white light Quantum Boards
Full-spectrum White and 660nm Red
Reliable passive-cooled design
Better canopy light penetration with diffused light
Inventronic Dimmable LED power supply included
Auto sensing power supply works on both 120VAC and 240VAC
This 1978 LED fixture can also be externally controlled with a RJ45,RJ14,BT Networking controller with main controller, featuring light timing, automated dimming (1% increments), temperature safety control, Sunrise & Sunset Mode for up to 100 fixtures per controller.
Universal Control Systems Compatibility
MEIJIU LED Fixtures can be fully controlled with either the MEIJIU main controller or with any other Control System that utilises 0-10V output signal （only with the same connector）. Even if your Universal Controller has an RJ port interface, you can still run our LEDs by using a signal converter RJ to 0-10V control adaptor.

Benefits include energy savings; MEIJIU LED solutions demonstrate the potential to save 40% on electricity and studies indicate that LED-lit canopies can generate more yield per kWh.
Flexible light intensity; MEIJIU LEDs can be dimmed to adjust PPF level to suit crop and growth stage without changing spectral power distribution or losing efficiency.
Less maintenance; MEIJIU LEDs are rated for 50,000 hours.
Reduced HVAC; MEIJIU LEDs are highly efficient and a less wattage consumption means less
