Lightech T5 4' 8-Bulb Fluorescent Grow Light | 432W 6500K - 120/240/277V
The Lightech T5 4' 8-Bulb Fluorescent Grow Light delivers 432 watts of 6500K vegetative coverage across eight 54-watt T5 bulbs. Unlike the standard 120V version, this fixture supports 120V, 240V, and 277V power configurations right out of the box. For growers with smaller footprints, the Lightech 4ft T5 4-Bulb Fluorescent Grow Light offers a more compact alternative, while those needing specialized solutions can explore the Lightech 2ft T5 Fluorescent Grow Light or high-efficiency T5 LED Grow Lights. It ships complete with all eight bulbs included, a UL-listed ballast, dual ON/OFF switches, and a 10-foot power cord — making it the most versatile and installation-ready fixture in the LighTech T5 lineup.

Frequently Asked Questions
This fixture supports 120V, 240V, and 277V power configurations out of the box. This makes it compatible with standard residential circuits as well as the higher-voltage systems commonly found in commercial greenhouse and facility environments.
The core output — 8 bulbs, 432W, 6500K — is identical between both versions. The key difference is voltage compatibility: the standard version is 120V only, while this fixture also supports 240V and 277V circuits. For growers exploring more energy-efficient options, our 400W LED grow lights provide a comparable footprint.
No — all eight 54-watt, 6500K T5 bulbs are included with the fixture. You can hang it, plug it in, and run at full 432W output immediately without any additional purchases.
Two independent switches allow you to power each bank of bulbs separately, giving you the flexibility to run at half or full output. If you need to interconnect multiple units, the Lightech Daisy Chain Cord is compatible with most strip-style grow lights.
The 6500K spectrum is optimized for the seedling and vegetative stages, delivering a cool daylight spectrum that promotes compact, healthy foliage and strong root development across a wide canopy footprint.
Yes. The UL-listed ballast has been independently tested and certified to meet North American electrical safety standards. Combined with multi-voltage support, this fixture is well-suited for large-scale commercial cultivation environments.
T5 fluorescent fixtures run significantly cooler than HID lighting, so they can typically be positioned 2–8 inches above the canopy during vegetative growth for maximum intensity. Monitor your plants for stretching or leaf curl and consult our guide on how far grow lights should be from seedlings for more specific advice.
