SUNPACK T5HO Strip Light - 18in - 17W - 6400K - with Snap-On Reflector

High-Output T5 Strip Light with Mirror Reflector for Seed Starts and Cuttings

The SUNPACK T5HO Strip Light is a complete 18in, 17W high-output fluorescent grow light system including a 6400K full-spectrum T5HO lamp, snap-on mirror reflector, electronic ballast, hanging hardware, and power cord - everything needed for immediate installation above propagation trays, seedling flats, herb gardens, and cutting domes. The super-slim design makes it easy to position in tight spaces, while the included mirror-like reflector directs light output downward to maximise the photon energy reaching the plant canopy below.

Key Features & Benefits

• Snap-on mirror reflector included - The reflector's mirror-like interior surface redirects light that would otherwise escape upward or sideways back down toward the plant canopy, significantly increasing the useful PPFD delivered at the growing surface for the same lamp wattage.
• 6400K full-spectrum T5HO lamp - The included 6400K lamp provides a blue-rich daylight spectrum that is ideal for compact, vigorous vegetative growth in seedlings, cuttings, herbs, and leafy crops throughout the propagation and vegetative stages.
• Electronic ballast for flicker-free operation - The integrated electronic ballast drives the T5HO lamp efficiently and quietly without the hum and flicker associated with older magnetic ballasts, providing consistent, comfortable light output for both plants and growers.
• Complete kit - lamp, ballast, hardware, cord - Ships as a complete, ready-to-install system with the lamp installed, hanging hardware attached, and a power cord included. No additional components are needed to get the fixture operational immediately.
• Super-slim design for tight spaces - The low-profile housing fits under shelves, inside clone domes, and in compact propagation setups where bulkier fixtures would not fit without restricting airflow or access to plants.

Who Should Use This

Home growers, nursery propagators, and small-scale cultivators who want a complete, ready-to-use T5HO grow light for seedlings, cuttings, herbs, and microgreens. The included reflector and super-slim design make it particularly well suited to under-shelf mounting and compact propagation stations where maximising light delivery in a small footprint matters.

Compatibility

The 18in T5HO lamp is replaceable with any standard 18in T5 High Output replacement tube. Compatible with SUNPACK hanging clips and link cords for suspension and daisy-chain expansion. For broader canopy coverage, multiple units can be linked together or used with the SUNPACK Universal Strip Light Hanger.

Frequently Asked Questions

Can I use this fixture without the snap-on reflector?

Yes - the reflector snaps on and off without tools. However, using the reflector is strongly recommended as it significantly increases the amount of light directed at the plant canopy, improving PPFD and growing results without any additional power cost.

Is the T5HO lamp replaceable when it reaches end of life?

Yes - the 18in T5HO lamp is a standard replaceable tube. Replace with any compatible 18in T5 HO lamp when output declines noticeably, typically after 10,000-12,000 hours of use.

How does this T5HO fixture compare with LED strip lights for propagation?

T5HO fluorescent lights produce a broad, diffuse light output well suited to even canopy coverage across propagation trays. LED strips offer longer lifespan and higher efficacy per watt. The T5HO with included reflector provides competitive PPFD for seedlings and cuttings at a lower upfront cost than LED alternatives.

Can I daisy-chain this fixture with other SUNPACK strip lights?

Yes - the SUNPACK T5HO Strip Light uses the standard SUNPACK link cord connector for daisy-chaining with other SUNPACK T5HO and LED strip lights. SUNPACK link cords are sold separately for connecting units at wider spacings.
