The light is a bit more intense than those with 3W chips, as this uses 5W LEDs instead – 110 of them. The optics are all jewel-quality glass focused at 90 degrees. In addition, it has two 15W UV-B tubes to enhance growth at the flowering stages. This panel runs cool and quiet with its built-in fans, and it comes with a 3-year warranty. California Lightworks is always a very well-recognized brand in the LED community, so you can’t go wrong here.
