Eye Hortilux PowerVEG 4' T5 Fluorescent Lamp

PowerVEG T5

This is THE BEST 4' T5 grow bulb available.

Have you ever seen a spectral distribution for a T5 grow bulb? Most likely you have not. That’s because what is currently available on the market is all the same. From brand to brand they have nothing unique or different to offer. The only real difference is their Kelvin Temperature and, contrary to popular belief, Kelvin Temperature does not affect plant growth in any way whatsoever.

PowerVEG is different. Not only does it produce a well balanced spectrum for your plants, it also provides UVA and UVB. UV is an essential component of the spectrum that produces stronger, healthier plants, allowing them to produce higher quality fruits and flowers. The sooner you introduce UV to your plants, the better your end product. No other T5 bulb on the market produces a spectrum with this quality or UV of any kind.

Why PowerVEG is like no other T5


  • First and only T5 to incorporate full spectrums of UVA and UVB (UVA = 315nm – 400nm : UVB = 280nm – 315nm).
  • Exclusive chemistry which produces UVA & UVB.
  • The only T5 grow lamp Made in the USA!!!


What PowerVEG does for your plants

  • Promotes extreme photosynthesis for faster growth.
  • Creates a stronger root system.
  • UV light allows for easy transition from indoor veg to outdoor flowering.
  • UV light helps develop stronger healthier vegetative plants that will produce higher yields and higher quality crops.
  • Creates faster producing yields, vivid colors, more flowering and better tasting crops.



  • PowerVEG can be used in any existing T5 54W HO lighting fixture


Recommend Light Cycles

  • If using all PowerVEG FS+UV lamps in one fixture, we recommend reducing the time the lights are on by 20%. This is due to the quality of the spectrum and the amount of UV coming from the light.
  • If using a 50-50 mixture of PowerVEG and standard T5 lamps, no need to reduce the time lights are on.

Recommended Height Above Canopy:

  • The recommended height above the canopy of plants should be between 8”-16”. The optimal height is 12”.


  • For Plant Growth Only
  • Product contains mercury. Please dispose of properly in accordance with local disposal laws.
  • Product emits UVA and UVB rays. Avoid prolonged exposure to skin and eyes.
  • Lamp may shatter and cause injury if broken
  • ANSI RG-2: CAUTION: Product emits UVA and UVB rays. Possible skin or eye irritation can result from exposures exceeding 30 minutes when working less than 8 inches from the lamp. Use appropriate skin and eye protection.
  • UV EXPOSURE: Growers working more than 18” away from the light source will have minimal UV exposure.
  • Lamp may shatter and cause injury if broken.

Suggested HORTILUX PowerVEG Formulas

Each PowerVEG grow lamp produces a different light spectrum for your plants. Growers can customize their own light spectrums with various combinations or they can use one of our suggested formulas. EYE HORTILUX has recommendations for 8-lamp and 4-lamp fixtures to produce the best results for your plants in the vegetative, flowering and start-to-finish set ups.

Suggested VEG Formula

To produce the VEG spectrum, select the corresponding base colors and install lamps as shown in your 8-lamp or 4-lamp fixture. The suggested VEG formula produces a large amount of blue light spectrum to enhance the vegetative growth cycle. The combination of the FS+UV, 420 & 460 provides the most vegetative focused light spectrum on the market.

Suggested FLOWER Formula

To produce the FLOWER spectrum, select the corresponding base colors and install lamps as showing in your 8-lamp or 4-lamp fixture. The suggested FLOWER formula allows T5 growers to utilize the spectrums that trigger fruiting and flowering. These red spectrums are typically not available in standard T5 lighting. The combination of the FS+UV, 633 & 660 provide a unique flowering spectrum no other T5 on the market can offer.

Suggested START-TO-FINISH Formula

To produce the START-TO-FINISH spectrum, select the corresponding base colors and install lamps as shown in your 8-lamp or 4-lamp fixture. The suggested START-to-FINISH formula allows T5 growers the ease to set it and forget it. No need to switch out your lights. Just insert this one formula and produce high quality growth and yields.

What HORTILUX PowerVEG T5 Grow Lamps Do for Your Plants

PowerVEG T5 Grow Lights help you get the best yields from your plants. It all starts with strong base from the PowerVEG FS+UV, which provides a well-balanced spectrum that closely mimics natural sunlight. From there, you can mix different PowerVEG colors to produce one of the formulas suggested above or create your own customized light spectrum

PowerVEG colors provide nanometer specific light to further enhance the FS+UV during the vegetative and flowering growth cycles. This allows for structurally sound plants ready for transition to HID where bigger and better yields and more overall production will be seen.
