Why PowerVEG FS+UV T5 Grow Lamp is Like No Other Fluorescent Grow Bulb 

Many fluorescent brands focus on promoting Kelvin temperatures. Contrary to popular belief Kelvin temperature does not affect plant growth in any way. The FS+UV is different because it:

  • Is the first and only T5 grow light to incorporate a full, broad spectrum and UVA and UVB light, both of which are important for strong, healthy plant growth (UVA = 315nm – 400nm : UVB = 280nm – 315nm).
  • Has the exclusive EYE HORTILUX spectrum.
  • Is the only T5 grow light made in the USA!!!

You can learn more about the benefits of UV light in our Grow Guide.


The FS+UV can be used in any existing T5, 54 watt, HO (high output) lighting fixture.

Recommend Light Cycles

  • If running 24 hours ON with standard T5, reduce cycle to 19 hours when using 100% FS+UV grow lamps.
  • When using a 50% FS+UV & 50% standard T5 light mix – NO CHANGE in light cycle necessary.
  • When using one of our suggested formulas—NO CHANGE in light cycle is necessary
