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.

Best for a large PC case, works on smaller towers with mods
This thing is solid! I strongly recommend setting your tower on it to get a feel for the orientation you want before attaching it to your desk or wall. I had to re-mount mine because I had it positioned too far back to be able to plug cables into the PC tower. When the ad says its for a large PC tower they are not joking. I would consider my PC case to be a fairly average size but the bottom clamp and side arms don't hold my case at all. Theres a z shaped bracket included to attach to the main support and let it contact the desk or wall surface behind it. I used this part to wedge between the bottom clamp snd my PC case to hold it in place. My mount is still very sturdy without that bracket in place. I cheated during install and stacked some books under it to bring it up to the height of the bottom of my desk, made easy work of it. I really want to give it 5 stars but unfortunately the fitment issue leaves me hanging, literally. Maybe I will update my rig and get a larger PC case down the road. What I love about this item is my tower used to be on my desktop. Now its tucked away neatly and I was able to separate my 2 monitors more. Feels like a whole new workspace with less clutter and more table space for projects. Good item.

Attractive design+color, slender profile, excellent functionality, budget price (8 outlet model)
Color: Black, Size: 8 Outlet, Style: Outlets Only, Color: Black, Size: 8 Outlet, Style: Outlets Only
This is exactly what I wanted. (It’s even better - slimmer, easier to handle cord, than the Belkin in this design style.) Perfect fit for the lower shelf of my night table. To charge my phone, iPad, Bluetooth headset, and the like (plug my lamp into it as well, for convenience-sake not surge protection). The 8 outlets are perfectly spaced/placed. I briefly considered the model with the USB cord plugs directly into the unit, but for me, at this point, for this purpose the extra price didn’t seem worth-it. My USB charging adapters aren’t that bulky, and with this design they can be plugged side-by-side. I do like the convenience of that design, with the USB plugs, and will likely get it in the future, and move this one to either my home-office, or dressing area. So, this “basic” one wouldn’t be wasted. And meanwhile it’s a great budget option that sacrifices none of the design, style, or function. It’s attractive, useful, well conceived/designed and executed. For well under $20. Nice color too. Would be perfect anyplace. Though I’d think this more basic model isn’t intended for multiple multimedia devises all in one - looked like they had more suitable models for if you wanted to say plug in your TV, your game console, your streaming and/or cable - do they still call it that? - box/devise, your speakers with or without subwoofer, along with your modem and WiFi-router all into one. Someone, who works with high end electronics and/or an electrician/engineer correct me if I’m wrong. But I’d get a model - of this same device if there’s one of suitable capacity - which that’s meant to handle such a load for my entertainment center. I think another reviewer talked about joules and capacity, I think it was for this model. Or at least this manufacturer. Though I don’t see it being convenient for travel - not sure about that question there, maybe more convenient than some other styles; certainly not anywhere that’s not 120V, and I doubt that at this level it’s sufficient protection for anywhere with radically irregular electrical/voltage supply, not just the occasional spike, like say - Malawi Africa for a random example out of personal experience, for something like that you’d actually have to spend money and get a proper UPC, not to mention bulky-bulky, but that’s not relevant here, for this, just this isn’t something like that. This is for use with stable electrical and voltage supply, should give perfectly adequate protection for the occasional spikes and surges such as those following a power outage, within the design specification.

Excellent value from a reliable & known brand
Color: Black, Size: 8 Outlet, Style: Outlets Only
I've always bought surge suppressors and the like from APC. They're very reliable and well-made. The equipment protection guarantees are great, too. This strip is not as sturdy as some other APC strips, but it is also less expensive. Perfect for basic home use (a TV, Xbox, etc). I'd get a higher up APC model if you're protecting a workstation computer or high end audio gear. But for basic stuff, this strip is a good value. I'd trust this far more than a lesser known brand.

APC is a trusted brand - this guy is beautifully thought out!
Color: Black, Size: 8 Outlet, Style: Outlets Only
It's hard to get excited about a power strip- but when they designed this one, the engineers at APC hit it out of the park! I love how the 'wall warts' (those odd klunky AC/DC power adapters that so many devices come with nowadays) have their own spot on this unit, and do not block out the remaining plugs that regular AC power cords (3 prong grounded) require. This is VERY important! Most of the competition has you forfeiting one or more plug locations when a wall wart blocks you out! There are on/off status lights (green means OK) and and on/off SWITCH. For the modest and reasonable cost, you get great surge protection. I have used APC products for many years, particularly fond of their backup UPS power supplies. I plan to buy more of this model for my apartment. The quality is there, a nice heavy line cord to connect to the AC power, and better-than-average build quality. Slick!
