Mixed (full) spectrum would be a T5 fluorescent or a cool white LED. Blue is used on vegetation stage and red for flowering

The LEDs are blue in all models. The colour refers to the mechanical switches. Red is a smooth, light switch primarily used for gaming. Black is smooth but a bit heavier. Blue is a tactile, 'clicky' switch which is nice to type on, and Brown is a sort of inbetween which has a tactile bump but no click.

There is a red light that turns on when you plug it in to charge, and when it is fully charged the light turns blue.

I wondered too and the answer is not in the manual which is just a paragraph or two. My guess is that the red light indicates the power is on and is recharging the battery. That makes most sense.

A red light means your speaker needs to be charged or is charging. hope you find this helpful.

It means the device needs charging... once the device is charged the light will turn blue.

I'm guessing they are going with red+blue = violet, red+green = yellow, blue+green= teal, and red+green+blue= white. These colors only appear in the areas of overlapping colors. The lights are so close together that there is some overlap. It is unmistakably RGB, but on a white wall, other colors, particularly white, can be seen.

The light isn't blue at all--it starts out red and gets gradually brighter/whiter but it's always a warm toned light.

There are three LEDs color lights: yellow, blue and red. There is switch that allow you to set the lights to yellow only or colors only. These alternate from yellow, to blue and then red. They are great lights!

the solid red light is known as a bloom booster. the solid blue one is known as a vegetation booster. if you're looking to grow house plants or any other plant from start to finish a red and blue combination is best. red light will make your plants elongate and stretch , blue light will make your plant compact and bushy. both blue and red together will grow a good plant.

I have used both red and blue lights separately and together. I find they work best separately. It takes longer to see results when the lights are combined.

1 switch is for the blue lights, and the other switch is for both the red & white lights. so if the white lights are on, the red lights are automatically on as well

Red Light means charging, and off means charged....that simple. Amber is only when it's on.
