California Lightworks 440W LED Grow Light definitely falls under one of the more expensive lights on our list, but this is one situation where you get the results you pay for. This particular unit comes in a bright red color – a stark change from subtly-colored light panels from other manufacturers.
The light is a bit more intense than those with 3W chips, as this uses 5W LEDs instead – 88 of them. The optics are all jewel-quality glass focused at 90 degrees. Plus, it has two 15W UV-B tubes to enhance growth at the flowering stages. But this panel runs cool and quiet with its built-in fans, and it comes with a 3-year warranty.
