Got an entire flood tray of clones you need to grow? Need to cover lots of leafy greens and herbs without heat burn or light bleaching?

Then you’re going to need the Yield Lab 4 Foot 8 Bulb T5 Fluorescent Grow Light Panel with 54 watt 6400K bulbs (included) for your low intensity growing needs.

Unlike high intensity discharge bulbs like HPS and MH lights, T5 fluorescents are made to keep intense heat to an absolute minimum. But don’t let that scare you, because each of the bulbs in these grow lights packs 54w (432w total) of cool blue spectrum, which is what vegging plants, clones, and non-fruiting plants love most.

With its multi-angle reflective design, this light reflectors give you a wider coverage area than other T5 fixtures. You’ll be able to cover a few rows of plants or a table of clones with all the power you need.

If you’re running an LED or HID garden and there are gaps in light during your garden’s vegging stage, just hang this light anywhere you need to fill in lights (on top, below, or on the side of your garden) and in seconds you’re giving your plants every bit of the blue spectrum they need.

Installation and use are far easier than HPS and MH grow lights.


Yield Lab 6400K 4 Foot 8 Bulb Fluorescent Fixture Setup

  1. Unwrap the grow light reflector panel and clear any dust away from the reflector and lamp sockets
  2. Carefully unwrap one of the T5 fluorescent lamps, align the prongs on both ends of the bulb with the sockets on each side of the fixture
  3. Insert the bulb so that it easily slides into place. Then carefully twist the bulb 90° away from you until you hear the bulb click and lock into place
  4. Carefully do the same with each bulb, facing each bulb in the same direction as the first
  5. Once the bulbs are aligned and installed, carefully turn the light fixture over to get the cables ready for hanging
  6. Using rope ratchet hangers (or any strong hangers you prefer), loop the loops of the cable on each side of the light to each hanger, adjust the light to your desired height and you’re ready to grow!

So whether you’re looking for a low-cost way to get your clones and greens through their vegetative stage, or you’re looking for an extra bit of vegetative spectrum light, the Yield Lab 432 watt T5 Fluorescent Grow Light Panel with 8 bulbs of 54 watts each (6400K) is what you need.

Hang it as close to your plants as you need for intensity, or far enough to cover a larger area. With this T5 grow light panel you’ll get twice the power you will out of a 4 bulb setup with twice the intensity!
