Lightech T5 4' 8-Bulb Fluorescent Grow Light | 432W 6500K - 120V
When a 4-bulb fixture isn't enough to cover your canopy, the Lightech T5 4' 8-Bulb Fluorescent Grow Light steps up with double the output. Running 432 watts across eight 54-watt T5 bulbs at 6500K, this fixture delivers intense coverage for larger vegetative grow spaces. While some growers are transitioning to a T5 LED grow light for energy efficiency, this fluorescent model remains a reliable high-output standard. It ships complete with all eight bulbs included, a UL-listed ballast, dual ON/OFF switches, and a 10-foot power cord — everything you need to get growing immediately.
Features
8 Bulbs Included — 432W Ready
All eight 54-watt T5 bulbs are included. Hang it, plug it in, and run at full 432W output from day one — no extra purchases needed.
6500K Natural Daylight Spectrum
The 6500K color temperature replicates natural daylight, providing indoor plants with the same quality of vegetative light they'd receive growing outdoors.
High-Lumen T5 Output, Low Heat
Eight T5 fluorescent bulbs deliver high lumen coverage across a wider canopy footprint while keeping heat output low — protecting plants even at close range.
UL-Listed Ballast
The UL-certified ballast meets North American electrical safety standards, making this fixture reliable and suitable for both daily home grows and commercial operations.
Dual ON/OFF Switches & 10-Foot Cord
Two independent ON/OFF switches let you control each bank of bulbs separately, while the 10-foot power cord provides flexible placement in most grow room setups.

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, this fixture is designed for standard 120V circuits. If your grow room runs on higher voltage (240V or 277V), the multi-voltage version of this fixture is available separately and supports those configurations.
Yes. The UL-listed ballast has been independently tested and certified to meet North American electrical safety standards, making it reliable and suitable for both home and 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 (too high) or leaf curl (too close) and adjust accordingly.
