We have been waiting months for this totally new high output Fluorescent lamp, and the wait is finally over! EYE Horitlux has nailed it again with the PowerVEG T5 lamp.
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.

PowerVEG is the first and only T5 to incorporate full spectrums of UVA and UVB, and is the only T5 grow lamp Made in the USA!!! What can you expect when you add just one or two PowerVEG lamps to your T5 light fixture? (Even adding just one PowerVEG can make a big difference in the performance of a 4 lamp T5 fixture, BTW) Adding the PowerVEG will promote extreme photosynthesis for faster growth; create a stronger root system; and allow for easy transition from indoor veg to outdoor flowering. You will also see that the UV light helps develop stronger healthier vegetative plants that will produce higher yields and higher quality crops. Your grow room will reward you with faster producing yields, vivid colors, more flowering and better tasting crops.

PowerVEG can be used in any existing T5 54W HO lighting fixture. 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. We have personally just added one PowerVEG to bank of four T5 fluorescents. We recommend the height height above the canopy of plants should be between 8”-16”. The optimal height is 12”.
