Yield Lab specializes in providing your plants exactly what they need to give you the yield you want, and with these 54w T5 Fluorescent Grow Light Bulbs you’ll get intense vegging light without giving your plants excessive heat.

T5 fluorescent bulbs give off a soft light that’s perfect for providing your plants light they need and not overpowering them like HPS and MH bulbs do. And unlike LED’s, you can hang these lights as close as 1” away from your plants without them bleaching your canopy.

The cool blue spectrum of this light stimulates vegetative growth in plants. Clones, veggies, leafy greens, and flowers that are in the vegetative stage all thrive on the 6400K spectrum these bulbs give you. No matter if you’re running a single bulb over a couple of clones or 5+ bulbs over a whole bed of flowering plants, Yield Lab’s 54w T5 Fluorescent Grow Light Bulbs are what you’re looking for.

Installation and use are simple:

  • Carefully unpackage each bulb you wish to use with gloved hands (the oils of your hands may affect the use of these bulbs)
  • Align the bulb in to the reflector
  • When the plugs are aligned in the socket, gently turn the bulb until it clicks in to place
  • Repeat with the desired amount of bulbs, and you’re growing in no time

Compatible with a whole host of T5 grow light fluorescent reflectors, grow your plants without all the extra heat and energy by growing with Yield Lab 54w T5 Fluorescent Grow Light Bulbs (6400k) today!

Product Features:

  • Each bulb offers 54w of power, giving you a total of 270w’s when used together- even more if you use 5+ bulb fixtures!
  • 6400k Cool Blue Spectrum is perfect for flowering plants in their vegging stage, growing clones and seedlings, leafy greens, chili’s, and peppers
