This lightweight (5.6 lbs) and low profile (1.7″) fixture can be hung in multiple configurations to fit any growing environment. Active Grow T5 HO Horticultural Lamps feature lower power consumption, double the PPF efficiency and 100% more effective spectrums for plant growth. Comes complete with 4 LED tubes, 2 hanging hooks, 120V power cord and dual on-off switches to allow growers to run 2 or all 4 lamps at a time. Covers a 2’x4′ area. The universal voltage 120-277V fixture can be connected via daisy-chain for up to 8 fixtures on 120V circuits and up to 16 fixtures on 208/240/277V circuits. For use in various hydroponic applications.

Note: This fixture is for use with Active Grow T5 HO Ballast Bypass 4FT LED lamps only. Fluorescent lamps may not be used with this fixture as it does not contain ballasts.

  High Performance & Energy Saving.

New all-PC body provides growers with a lightweight, high-performance LED fixture with 10% higher PPFD output than the previous generation. Uses 60% less energy than 54W T5 HO fluorescents when used with Active Grow 25W T5 HO LED lamps, saving over $480 in energy costs over the lifetime of the lamps.


Bypass the Hassle – Line Voltage Lamps

Lamps run directly off line voltage 120-277V. No ballasts means no buzzing, flickering, compatibility or longevity issues, giving your plants pure, uninterrupted lighting.


Sun White / Sun White Pro / Red Bloom Pro Spectrum

Choose between the Sun White Spectrum with a high CRI that mimics natural sunlight conditions and includes additional Red and Far-Red wavelengths to boost photosynthesis rates, the Sun White Pro Spectrum that promotes healthy vegetative growth, root development, tight internodal spacing and phytochemical production and the Red Bloom Pro Spectrum that increases plant mass, speeds up growth and promotes healthy root development, budding and fruiting in purely indoor environments.


Longer Lifetime

No ballasts means an extra long lifetime with little to no maintenance costs for years of use.


Certified Safe

All fixture components and manufacturing processes meet the highest industry safety standards.


Rebates Available

Typical Applications

Commercial vertical farm or home grow racking systems for citrus, orchids, microgreens, leafy greens & cannabis vegetative stages.



Blue 400-500nm- Improves overall plant health and quality including taste, aroma, color and nutrition. Helps promote plant compactness and root development.

Green 500-600nm- Increases overall plant photosynthetic efficiency and penetrates the canopy to encourage growth of lower leaves. Makes detecting issues like pests and disease on plants easier to see.

Red 600-700nm- Promotes plant photosynthesis and increased biomass. Essential for leaf expansion and stem growth. Helps regulate plant flowering, photoperiod and germination.

FR/IR 700-800nm- Promotes expansion and stretching of leaves and stems. Penetrates the canopy to encourage growth of lower leaves. When used with 660-680 nm wavelengths, plant photosynthesis rates increase via the Emerson effect.


Sun White

High CRI 95 full-spectrum light accentuates plant colors, making visual inspection easier. Includes additional Red and Far-Red wavelengths to boost photosynthesis rates.

Sun White Pro

Professional grade production spectrum formulated to promote healthy vegetative growth, root development, tight internodal spacing and phytochemical production.
