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 and keeping fish healthy. The T8 PhotonTube™ offers 33 umols/sec of photon output, with spectral coverage across the PAR spectrum from 420 nm to 800 nm.

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.

Because this is a full-spectrum product, the resulting light output is a soft white color that simulates natural daylight. The high CRI rating ensures that your coral colors will pop, and fish colors appear as natural and vivid.

These T8 LED tubes are UL Type A and Type B compatible, meaning they can be used with or without a fluorescent ballast. Plug it in directly to your existing T8 fixture, or a new fixture with the ballast removed - whatever is easier!
