Who This Is For
- You are adding a red-enhanced light because your multi-stage LEDs are not pushing the flower density you need.
- You are swapping out old T5 fluorescents because failing ballasts and high heat are ruining your canopy climate.
What We Found
- The dual switches allow you to drop the intensity for younger plants without having to raise the entire fixture.
- The polycarbonate body stays much cooler to the touch than the old metal T5 housings we used to stock.
What Users Say
- Growers who switched from old T5s say their rooms are finally quiet now that the ballast buzz is gone.
- Users running tiered racks say the thin profile let them add an extra shelf without crowding the canopy.
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.
