Exclusive Limited Time Offer: GrowAce.com customers will receive a FREE pair of Yield Lab LED grow room glasses with the purchase of the Horticulture Lighting Group HLG 300L B-Spec LED Grow Light ($29.95 value!)

The HLG 300L BPSEC LED can replace a single-ended 600-watt HID while consuming only 270-watts power. The LED system is powered by two custom white-light quantum boards with Blue 470nm and Samsung LM301H LEDs. The blue color stimulates the production of chlorophyll and encourages the growth of thick leaves. This light is specifically designed for the vegetative growth phase.

  • Samsung LM301H LEDs: These are the best quality LEDs available in the market that deliver the highest photon efficacy.

  • Smart Heat Management: The passive heat management system uses heatsink to dissipate heat efficiently and ensures that the system performs to its full potential.

  • Diffused-Light: The scattered light emitted by the LEDspenetrates the plants deeply, which allows them to absorb more CO2 to achieve stable growth.

  • Dimming Feature: You can adjust the intensity of light according to the seedling stage and flower stage. Dimmable from 90-watts to 270-watts. Allowing you to reduce the power consumption when required.

  • 3 Year Warranty: Industry leading 3 year warranty included

The grow light system has two quantum boards that have Samsung LM301H blue 470nm LEDs. The Samsung LM301H LEDs deliver the highest photon efficacy and can help indoor farmers to maximize the plant growth and its quality. The blue 470nm wavelength encourages the production of chlorophyll, which leads to the production of thicker green leaves, compact vegetative growth, and strong stems.

The grow light system is the complete value for money as it promises excellent results. Its system efficiency, PPF efficacy, and total output are 158 Lm/W, 2.5 μmol/joule, and 675 PPF, respectively.

The new and improved system is longer and has dimensions 26" x 10" x 3". As it has a long design, therefore it can provide light evenly to a wider area, making it ideal for commercial indoor horticulture practices. The grow light supports vegetative growth and its footprint is 4' X 4'.

The recommended mounting height of the grow system is 18 to 24 inches above the plant canopy.

The LEDs provide light to the plantations in diffused or in the scattered form so that any direct harsh light does not damage them. Diffused light maintains the low temperature of the plants that ensure even growth and higher production of superior quality products.

You can take control of the light intensity of the grow system with the help of the dimming feature. The wattage output ranges from 90-watts to 270-watts. With the dimming feature, you take control of the sleep and wake-up time of the plants, adjust the intensity according to the requirement of the different stages.
