What is a Cree Grow Light?

A Cree grow light is a lighting system featuring LEDs made by the Cree company. Cree creates some of the highest output LEDs in the industry. Plus, they are incredibly efficient to operate, saving you money on your power bill.

How Does a COB LED Work?

COB LED grow lights reflect a recent trend in the indoor gardening space. An acronym for Chip-on-Board, COB offer many benefits over traditional options. They use an alternative packaging technology than regular LEDs, allowing multiple lights to form a single module. When lit, the tiny lights resemble a cohesive light source instead of looking like several individual bulbs.

Often, COB LED grow lights have increased efficiency, longer lifespans, and better light quality. This can lead to increased yields and stronger plants, allowing them to get the most from your indoor garden. Plus, the higher packing density means you get more light in a smaller size device.

Cree COB LED grow light systems are some of the most popular options around. While there are other COB LED grow light producers who also craft great products, many consider these systems to be some of the best available.
