Active Grow T5 HO LED Grow Light Replacement Bulbs

Active Grow T5 HO LED Bulb
Product Review

The Active Grow T5 HO replacement LED bulbs are the next evolution in plant lighting technology. Fluorescents have offered a decent balance in efficiency and plant growth. They've continued to push the limits, with T5s offering a low heat, linear light source that works great in tight spaces.

LEDs have been leading on many fronts, offering full spectrum solutions that are even more efficient. But many LED lights require a significant distance away from the plant canopy to achieve optimal light dispersion. This is where the Active Grow bulbs come into play. They fill a vital gap in the broad range of LED form factors!


Active Grow LED bulbs are a complete replacement for your old T5 fluorescent bulbs. They are finely tuned for optimal efficiency. Requiring only 45% of the power, these LEDs perform just as well as conventional T5s. This is not a regular indoor lighting solution. The Active Grow bulbs are designed specifically for indoor growers. They've been used in commercial operations for the production of lettuce and herb plants. My testing has revealed LED T5 HO replacements to be excellent performers!

- 24w Actual Power Draw
- Full Spectrum Light, Optimized for Plants
- Operational Distance: 3 Inches
- Mercury Free / Recyclable / Shatterproof
- Passively Cooled / Very LOW Heat Emission
- UL Listed / 30,000 hour Lifetime

These lights are perfect for an operation with existing T5 infrastructure. In most cases, they are literally plug and play. (Just be sure to check their compatibility list.) As old fluorescent tubes burn out, they can be upgraded with these LEDs for a serious reduction in operating costs. Depending on your usage scenario, you may find that the lights have paid for themselves in energy savings in the 1st year. It all comes down to annual hours of operation and local electrical rates.

If you're running a full time operation and have been relying on T5 grow lights, I recommend running the numbers and seeing how quickly these lights could pay for themselves. If you're in a warm climate, don't forget to account for reduced cooling costs. LED T5s make MUCH less heat.

For small scale hobbyists, the upfront price is fairly competitive. You need to analyze how many months out of the year you'll be running them. The lights are excellent quality and they perform very well. But if you're just starting out, you might want to look elsewhere, especially if you don't already own a T5 fixture.

On the other hand, if you already own a T5 fluorescent grow light, switching to the LEDs will enable you to grow year round at a reduced operation cost. I personally am considering growing hydroponic lettuce throughout the Winter since the electrical costs will be so much less!
