Product Overview

PhotonTube™ is a new LED tube product line that has its light output tuned to the spectral and intensity needs of growing plants. The T5 PhotonTube™ offers 48 umols/sec of photon output, with spectral coverage across the PAR spectrum from 420 nm to 800 nm.

Because this is a full-spectrum product, the resulting light output is a soft white color that simulates natural daylight, rather than the harsh pink/magenta light color typically seen in grow lights. This makes it easier and more comfortable for you, the grower, to see and observe your plants, and spot any diseases or infestations before it's too late.

Our PhotonTube™ LED grow lights are available in 4000K and 6500K, with 95 CRI and R9 > 80 - this indicates a color spectrum that comes very close to natural sunlight.

Simply remove that old T5 fluorescent bulb, and replace it with our T5 bulb and you'll be up and running in seconds!

4000K provides an excellent spectral output for strong growth and flowering. In addition to strong output in the blue 450 nm region, RedBoost red phosphor technology ensures sufficient coverage in the deep red portion of the spectrum past 700 nm, targeting chlorophyll A absorption in particular.

The spectral ratio simulates late-season light, stimulating plant processes that encourage flowering and fruit growth.

The 6500K spectrum comes very close to natural daylight, truly simulating what plants have adapted to over many generations. It is especially well suited for seedling growth, and helps to prevent them from becoming "leggy" as the spectral dosage perfectly matches that of natural daylight.

Plants in the seedling stage require significant amounts of blue light to encourage vegetative growth, as it is similar to a high sun-angle spectral composition that is typically observed in early-season grow periods.

Seedling and vegetative growth are absolutely critical components of healthy plants. Without a healthy foundation, plants can suffer from stunted growth and limited yield.
