This is a handy feature, especially if you are experiencing any issues such as nutrient deficiencies where you want to see how the plants actually look. There is also a feature that, with the touch of a button, puts the lights into a natural light mode, allowing for inspection of the plants without being colored by the red and blues of the LEDs. I've not yet used this feature, preferring to change programs manually based on how the plants are developing. Those individual programs can then be run as a "season", where the controller will automatically switch from one program to the next throughout the complete growth cycle. Multiple programs can be setup for each growth stage, veg, pre flower, flower and finishing, allowing the light spectrum to be tailored for each phase. The controller has some nice features and without it, custom programming of the lights isn't possible. These are without a doubt the best LEDs I've used. I made the decision to go with the CLW 1100 UVBs and I'm glad I did. When my two Kind XL1000s failed last year I had to purchase replacements. Over the years I've had the opportunity to use many different LED grow lights including GrowLedHydro, Goldstar, FERO, Lush and Kind.
