The HLG 650R can easily replace a 1000W HID lamp. The dimmable unit withdraws a wattage range from 60 to 630 watts and can deliver upto 1770 umol/s of light. The LED delivers an efficacy of 2.81 umol/j. The LED emits dispersed light, allowing better canopy penetration and providing equal distribution of essential spectrum light without damaging the plant.

  • Dimmable Drive:The lights are highly efficient and can be dimmed according to the requirement of the plantation type. You can adjust the lighting by 10%.

  • Samsung LM301H LED: The LED emits a full-spectrum light with 4000K color temperature, ideal for flowering and vegging purposes.

  • Diffused Light: With diffused light, the corners of the plantation, and in the absence of the light concentration, the plants do not get damaged.

  • Passive Cooling: The LED grow system cools down using the thermodynamics of conduction, so no unnecessary electricity is wasted and helps save on electricity bills.

The grow light uses a Qb 648 quantum board designed by HLG and Samsung. The 648 uses 660nm deep red and 4000K diodes. The board's efficiency is improved with the high temperature and double the number of diodes on the board.

It has been designed to replace a 1000W double-ended grow light and emits 30% more than 550 HLG light. The 650R stands as one of the most powerful fixtures today in the market.

The grow light board can be used commercially and for home grows. With the ETL certification and 3-year warranty, you can stay completely assured about your investment.

Using the dimmer to adjust the grow light intensity is recommended for vegetative growth and cranking the light intensity for flowering purposes. The total light emission of the grow light is reported at 1770 umol/s and efficacy of 2.81 umol/J, which is an impressive number.

The LED must be installed 30-35 inches above the canopy for application. Anywhere closer than this may end up burning the plants as the light output is too high.

The fixture is ideal for a 5 X 5 area but can also be used for a 4 X 4 area. The LED provides light to a 7’ X 7’ vegetative area and 5’ X 5’ flower area. Hang the fixture at a distance of 30’’ for flower and hang the fixture at a distance of 48’’ to facilitate vegetative growth.

The grow light is recommended for supporting the full-growing cycle from seedling to flowering. It is ideal for soil, aeroponic, aquaponic, and hydroponic systems.
