The colour temperature of a light refers to the type of light that is given out by a lamp. Early in the growing season when the days are long, plants expect to see more daylight in the 5500-7000K temperature range.
Near the end of summer and into autumn, plants expect to see cooler temperatures and longer sunrise and sunset periods in the 2700K range.
SunBlaster lighting is available in a variety of lighting temperatures to allow growers to accurately replicate the ideal growing environment for their specific indoor growing needs.

In Fluorescent lamps, the estimated life refers to the number of hours that a lamp will continue to deliver optimal grow lighting before it should be replaced. Over time, the quality of light delivered by fluorescent lighting degrades, and while the light may continue to operate well beyond the number of hours specified, it may no longer be providing plants with the ideal lighting conditions they desire.
LED lighting is designed to deliver optimal growing light over the lifetime of the product, and does not contain user replaceable components. The estimated lifetime for LED lighting refers to the number of hours or years (based on 12 hours per day of use) that the lighting is designed to operate.
Environmental variables and operational stresses may reduce the estimated lifetime of any light fixture.
