Barrina T5 Grow Light 3ft 128W (8x16W)
Full Spectrum (Pinkish White) designed to replace conventional 800W lighting with a compact 128W setup. The Barrina T5 3ft fixture uses 768 LEDs to optimize absorption, delivering high PPFD for seedlings, vegetative growth, and flowering. The system emphasizes efficiency, with over 95% of emitted light being usable by plants. Each of the eight 16W bars includes an individual on/off switch, enabling tailored lighting schedules across a setup or bench. This modular approach supports scalable arrangements when growing multiple trays or beds.
Barrina 3ft 5000K Daylight White Full Spectrum (6-Pack)
This 3-foot strip series emphasizes 5000K daylight white within a full-spectrum approach, suitable for all plant stages. The updated design is compatible with Barrina GM cords and supports seamless linking to form longer runs. The lighting shell uses durable aluminum for better heat dissipation, helping extend the life of the LEDs. The V-shaped reflector design improves light distribution and increases overall efficiency, supporting robust plant growth with reduced energy use. Ideal for growers seeking a modular, scalable solution for larger bench spaces.
BoostGro LED Grow Light Full Spectrum 5000K + 660nm Red
BoostGro’s 3-foot, two-tube kit delivers full spectrum with enhanced red light at 660nm to support sprouting, flowering, and fruiting stages. With a modest 20 watts per unit producing 2400 lumens and 36 µmol/s PPF, this setup yields ample light with low heat. The included 2-foot hanging cable and inline switch simplify installation, and the design supports versatile hanging or mounting. This option suits compact grows where precise spectrum control and easy deployment are priorities.
Sunco 3ft Grow Light LED, 30W Full Spectrum
Sunco’s 3-foot, 30W LED fixture provides a full-spectrum output suitable for seed starting, seedling development, and ongoing plant growth. The unit’s linkable design supports larger installations and multi-tank setups, while energy-saving features reduce power consumption compared to traditional grow lights. Inline switch and suspended mounting options further simplify deployment in home and hobby grows, enabling straightforward scalability for 36-inch bed configurations.
Sunco 3ft Grow Light LED, 30W (2 Pack)
Top-rated for its full-spectrum output, this 3-foot setup supports growth across stages from seeding to bloom. The two-pack configuration offers cost-effective expansion for larger grow areas or stacked shelves, with a focus on energy efficiency and reliability. Its linkable design and inline switch ease integration into existing systems, making it a versatile choice for 36-inch grow tables or benches in domestic setups.
Buying Guide: Key Considerations For 36 Inch LED Grow Lights
Coverage: Match fixture length and light distribution to your growing area. A 36-inch standard works well for single large trays or multiple smaller trays in a row. Look for even PAR distribution across the central zone to ensure uniform growth.
Spectrum: Full-spectrum lights that emulate natural sunlight support all plant stages. Some models emphasize red or blue augmentations to boost flowering or vegetative growth. Consider whether you need generic full-spectrum or targeted spectrum enhancements for specific crops.
PPF and PPFD: Higher photosynthetic photon flux (PPF) indicates more light output, while PPFD measures light intensity at plant canopy height. Look for kits that optimize these values for your setup, particularly if you’re growing dense foliage or quick-growing species.
Efficiency and Heat: LED systems should minimize heat output while delivering adequate light. Aluminum housings and well-designed heat sinks extend LED life and reduce maintenance. Energy efficiency helps keep operating costs down in larger grows.
Ease of installation: Linkable fixtures, adjustable hanging hardware, and inline switches simplify setup and future expansion. Separate on/off controls per module offer flexible scheduling for staggered lighting in multi-bench environments.
Durability and warranty: Durable materials and reliable customer support reduce downtime. Check warranty terms and whether replacements are available for individual bars or tubes.
Plug-and-play vs. modular: If you plan to scale, modular bars or strips that can connect into longer runs provide maximum flexibility. For small setups, plug-and-play options with built-in switches can be quicker to deploy.
