All New HTG 3.0 COB LEDs

Looking for an LED grow light built by growers for growers? Look no further, the newly redesigned HTG 3.0 540w COB LED Grow Light is engineered to meet your needs. Featuring state of the art full spectrum COB LEDs, the HTG 3.0 is more powerful, more efficient, and built around a unique modular system; as a result, its one of the most practical and innovative systems available. HTG custom 60w COB LEDs emit more light and generate less heat than equivalent 60w LED panels, giving you more growing power for your flowers per watt. Secondary lenses refine light spread, creating a large light footprint and increasing light intensity and canopy penetration. For indoor growers that want robust flowering, potent vegetative growth, and heavy yields, the HTG 3.0 540w COB LED Grow Light exceeds expectations. Each fixture comes complete and ready to grow with 120v grounded power cord and hanging hardware.

COB LED Technology

State of the Art COB LED technology is the bedrock of the newly redesigned HTG 3.0 fixtures. COB stands for Chip On Board, a breakthrough LED packing technique which allows multiple LED chips to be mounted closely together to form a super-bright, intense, and efficient lighting module. Powered by our custom COB, each HTG 3.0 module produces an impressive 1.96?mol/watt* output, topping several industry leaders in efficiency and guaranteeing maximal photosynthetically-active light.

PODular Design

Keep up with innovations in LED tech using the HTG 3.0 modular LED system! Fully interchangeable HTG LED pods enable simple user-side modifications, eliminating the need to purchase an entirely new system when it’s time to upgrade. HTG 3.0 pods come in two models, both based off a 60w COB flanked by six (6) 5w LED chips, Full Spectrum & Full Spectrum + UV-A, the latter integrating a 380nm LED chip to provide beneficial UV light. The HTG 3.0 540w COB LED comes equipped with three (3) Full Spectrum pods and three (3) Full Spectrum + UV-A pods to ensure an equal distribution of UV-A light. Swap pods in just seconds to update, customize, or repair with no special tools or technical know-how required.
