This all-natural light spectrum boosts healthy growth rates for house plants, microgreens, flowers, fruits and more. By mimicking sunlight conditions with a high CRI of 95, the Sun White Spectrum will make your garden look more vivid and it will be easier to detect pests and deficiencies before they spread. This truly full-spectrum light extends beyond the traditional PAR range (400-700 nm) to include far-red wavelengths that increase photosynthesis rates via the Emerson Effect.
Plug & Grow
This plug and play LED grow lamp works directly with a wide range of Instant Start and Programmed Start T5 HO electronic ballasts including Hydrofarm Agrobrite Fulham ballasts and BallastWise ballasts. *Not compatible with all ballasts. Please check the T5 HO PLUG & PLAY 4FT LED GROW LAMP BALLAST COMPATIBILITY GUIDE before purchasing. Not compatible with single unit T5 fixtures.

T5 LED Grow Light Electronic Ballast Replacement Instructions
Follow along and learn how to switch out an old T5 fixture ballast for a new one that works with our T5 HO Plug & Play LED Grow Lamps.
Upgrading to T5 LED grow lamps from T5 fluorescents offers numerous benefits for plant growth and cost savings. With a longer lifespan and dedicated horticultural spectrums, LED lamps are more energy efficient, emit less heat and are environmentally friendly.
Robin from Cascadia Greens joins us to see how our Active Grow T5 HO LED Grow Lamps perform in an indoor hydroponic rack grow light spectrum test for Basil, Shiso, Sorrel & Edible Flowers.
Simple Greens Hydroponics takes a look at different lighting options for an indoor hydroponic system and recommends the Active Grow T5 HO Plug & Play LED Grow Lamps for increasing yields and saving energy costs.
Ive been running 8 of these in a two tier setup using two hydro farm 4 light T5 fixtures for one month.
primarily used for mother plants, and clone vegging The plants and I appreciate the drop in operating temperature within the operational space (grow tent). I was previously using 2x Veg+UV T5's in conjunction with a pair of 420nm T5's per fixture from EyeHorti$%^and temps would easily be 8 to 15 degrees warmer than ambient room temp, now its half that range of 4-8 degrees above ambient.
While I love the energy savings, I have had a harder time achieving nice slightly elongated shoots for propagation with the LED retrofits vs previous T5 setup. The internodal spacing is pretty tight and it takes a bit longer for the mothers to produce the size of shoots I prefer working with.
though I will note this could also be a result of adapting to a new light source. which by now they ought to be pretty well adjusted, so from this point on I will see if I can achieve previous benchmark of 2.5 wk propagation intervals.
Despite the growth delay Ive experienced, I am satisfied with my Active Grow retrofit T5's. Plants appear to like 'em.
They are pretty bright.
The high CRI makes it easier to properly identify pests and problems.
Cool operating temps + low draw = less energy needed for cooling = smiling faces.
These lamps have been a big improvement over my old fluorescent tubes. I live in a hot climate so I really appreciate that they stay cooler. The direct conversion tubes have been working just fine with my old fluorescent fixtures. I was originally going to go with the ballast bypass but have been so busy I needed a super quick option and these were perfect. My seedlings are healthy and growing by leaps and bounds!
Arrived as promised, great packaging - shipped all the way to Canada! Thank you! Lights run well and are doing great direct swap from T5HO fluoros.
Plants love these...For cuttings/seedlings, and throughout veg, these are excellent.
Light bulbs are great, don't have to worry about deficiencies of the light spectrum in your grow area . Energy efficiency is awesome and not much of the heat output. Customer service is outstanding. Thank you.
Works as expected, best investment for indoor horticulture. With all the choices out there right now this is the best, hands down.
(Active Grow review starts at 4:06) "These are really nice because you can convert a regular fluorescent fixture into an LED fixture just by switching the tubes. The nice thing about the LED tubes is that they use a lot less energy than the T5 ones do. The T5 fluorescent is 54 watts, each of the LEDs is 24 watts so you're right about half the energy usage. We've slowly switched over to LED from the T5 fluorescents and as we switched we found that our yield actually went up a little bit. You can buy these bulbs in different spectrums. This is the Sun White Spectrum but there are other ones that you could use as well. This one has worked really well so I would recommend it."
