Active Grow 25W T5 HO Ballast Bypass 4FT Horticultural Lamp

 Overview 

The Active Grow 25W T5 High-Output Ballast Bypass 4FT lamp is an LED tube that replaces 54W T5 HO 4FT fluorescent lamps and features lower power consumption, double the PPF efficiency and 100% more effective spectrums for plant growth.

All Active Grow T5 HO Ballast Bypass LED tubes work with existing T5 fluorescent light fixtures by bypassing the ballast and wiring the lamp holders (tombstones) to a single end. Without the need for a ballast, these universal voltage lamps (120-277V) do not flicker, buzz or experience longevity issues. All Active Grow T5 HO Ballast Bypass lamps feature a transparent PC body that protects against water damage and shattering without sacrificing photon output. T5 fixtures require non-shunted lamp holders. Lamps are non-dimmable.

T5 HO Fixture Electronic Ballast Replacement Instructions

How to switch out your old T5 HO fixture ballast for a new one that works with Active Grow T5 HO Horticultural Lamps

Why would you change out your T5 HO ballasts?

  1. Ballasts don’t last forever (10-15K hours for a good one) so in order to keep using your existing fixture you can just purchase a new replacement ballast that is cheaper than a new fixture.
  2. In order to use new T5 HO LED lamps that require electronic ballasts to run. To check what ballasts are compatible with Active Grow T5 HO Horticultural Lamps please click the link here.

What you need for the installation:
1: T5 HO Fixture
2: T5 HO Lamps
3: Twist on wire connectors
4: Screwdriver
5: Wire trimmer / cutter
6: New replacement ballast

*NOTICE* NOT ALL T5 HO BALLASTS AND FIXTURES ARE THE SAME SO BEFORE INSTALLATION MAKE SURE YOU REMOVE THE REFLECTOR TO CHECK WHAT TYPE OF BALLASTS WORK WITH YOUR FIXTURE AS BALLASTS ALSO COME IN DIFFERENT SIZES. MOST BALLAST REPLACEMENTS ARE AVAILABLE ON AMAZON FOR LESS MONEY THAN A WHOLE NEW FIXTURE.

*NOTICE* IF YOU HAVE A T5 HO FIXTURE WITH 2 OR MORE BALLASTS INSIDE THE SAME INSTALLATION RULES APPLY.

Perfect size, high quality
Size: 7.7" x 7.7" x 1.7", Color: Black (Metal Silvered)
I had a previous catch all tray that I bought on amazon, it used buttons on the 4 corners to turn a flat cardboard into a tray. Over time, the catch all tray got filled up, not just with a wallet, keys and eyeglasses but eventually business cards and other knick knacks. With all the items inside the tray, sometimes the buttons would start to pop out. It wasn't awful, more of an annoyance. But it was time for me to find a more durable tray. I looked on amazon and added 6 different trays that had "potential" into my shopping cart. Then I carefully evaluated each one and deleted them out of my cart until there was only one left. Some had multiple compartments. Some were larger than this one. I felt the ones with compartments would limit my ability to put the things I want in there. Also, I didn't want it so big that it took up too much desk space. Ultimately, I felt this was the perfect size. I'm extremely happy with it, the quality is really nice and it looks and feels durable. No more loose buttons and spilled knick knacks.

Keeps clutter away
Size: 7.7" x 7.7" x 1.7", Color: Black (Metal Silvered)
This works great to corral all my notes I write on post its or small notes. Keeping them hidden from the desk top b/c or the depth but still visible to me. Much better than keeping on the plotter. Looks great in quality .

Attractive, Simple, And Well-Made
Size: 7.7" x 7.7" x 1.7", Color: Orange (Metal Glided)
I use this as a "catchall". A place to stash things like my wallet and keys when I enter the door, so that I don't use them (I had been prone to that!). It serves it's purpose well. It's both sturdy and attractive, and a good size for a "catchall". Recommended for those like me who need such things.
