Active Grow T5 HO 2.0 4FT 4 Lamp LED Grow Light - Red Bloom Pro Spectrum

Struggling to achieve the flower density and fruit yields your plants are capable of? Standard lighting often lacks the specific red wavelengths required to trigger robust reproductive growth. The Active Grow T5 HO 2.0 4FT 4 Lamp LED Grow Light with Red Bloom Pro Spectrum is the professional solution, engineered specifically for flowering and fruiting stages to promote maximum bloom development and enhanced harvest quality.

This high-performance 100-watt LED system is a direct, energy-efficient replacement for traditional 216W fluorescent fixtures, slashing energy consumption by 54% while providing superior light quality. Unlike conventional T5 setups, this fixture features a ballast-free design, eliminating the common issues of buzzing, flickering, and expensive ballast failures. Growers looking for full-cycle performance might also consider the Active Grow T5 HO 2.0 Sun White Spectrum for the vegetative phase, or the 8-lamp version for larger canopy coverage.

The specialized Red Bloom Pro Spectrum is formulated with targeted red wavelengths that stimulate phytochrome responses, essential for transitioning plants into their reproductive phases. This results in stronger budding sites, increased essential oil production, and denser flowers. Built with a lightweight 5.6-pound polycarbonate body and dual on-off switches, this system allows for precise lighting management in any commercial or home grow environment. For smaller supplemental needs, the Active Grow Red Bloom 2FT strips offer similar specialized spectrum technology in a more compact form factor.

FAQs

What is the Red Bloom Pro Spectrum best for?+

The Red Bloom Pro Spectrum is specifically designed for the flowering and fruiting stages of plant growth. Its enhanced red wavelengths stimulate phytochrome responses that promote denser budding, increased essential oil production, and higher overall yields.

Does this fixture require a ballast?+

No, this is a ballast-free system. It uses direct bypass LED lamps, which means you won't have to deal with the buzzing, flickering, or energy loss associated with traditional fluorescent ballasts.

How many units can I daisy chain together?+

You can connect up to 3 units on a standard 120V circuit. If you are using higher voltage commercial circuits, you can daisy chain up to 6 units on a 277V circuit.

What is the recommended hanging height?+

For flowering plants with high light requirements, we recommend positioning the light 12 inches above the canopy for a 2'x4' coverage area. For low-light plants, it can be hung at 24 inches for a 3'x4' area.

Can I use this light for the entire grow cycle?+

While this light is optimized for flowering, the dual switch control allows you to manage light levels for different stages. However, for the best vegetative results, many growers supplement with a Sun White spectrum light during the early stages.

Solid little workhorse
Color: Space Grey
Works well. Key part of my espresso setup. Battery charge lasts. Easy to use. My only gripe is that the power switch can be hard (for me) to turn on and off without lifting it up to find it.

Worth it!
Color: Black
A necessity for anyone trying to elevate their espresso making game. I use this to measure my beans and to also measure the shot I pull and how long it takes to pull. It’s great quality and totally worth it. The scale is very quick to start when the shot starts to pull. Easy to use and a great scale.

Works prefectly, accurate, easy to use, and looks great.
Color: Black
I didn't expect much but it works really well and seems to be very accurate. It's much more sensitive (to 0.1g) than the scale I was using to measure my coffee and the autostart timer works really well. Also, unlike my other scale, this one is USB-C rechargable and so far has no indication of needing a recharge after a week or so of daily use. My other scale uses CR2032 batteries and goes through a pair every three weeks, so being able to recharge instead is quite nice. It's small and I can use it to time the extraction and also use it to measure out heated water for tea, or whatever I need. This is definitely a steal for the price.

Great value and full-functioned.
Color: Black
This is a simple, elegant little scale with timer. It's perfect for use with a small espresso machine like my Breville Bambino Plus. It shifts easily from counter use weighing beans before grinding, to placing on the drip tray to time and weigh shots. The top is smooth and water resistant. I think it's a great value.

Premium experience from a scale
This scale is not cheap, but it comes with a premium experience. The overall build quality is excellent, and it looks and feels great. Scale is extremely sensitive and response, and very consistent. Quick to zero, quick to turn on. Display is clear and easy to read. Well insulated from water, with only the bottom being semi-exposed to liquids (note that it is NOT waterproof, so still be careful - do not submerge it). It also has an espresso mode which can be toggled on/off. That mode will automatically tare when placing things on it, meaning you can weigh your beans, take off the bowl and put back on a cup to brew the espresso into, all without tareing manually. It also detects when you're actually brewing, and it does so by detecting a steady flow of liquid. This specifically can be a bit finicky, it may or may not work for you depending on your machine and how you brew. My only single complaint is the volume of the beeping. By default it plays a loud beep whenever you're using the touch buttons. It is very loud and I turned it off immediately. Unfortunately it seems there is no way to lower the volume on the beeps. Not a deal-breaker at all for me, but something to consider if you care about audio feedback.
