SUNPACK T5HO Strip Light - 3ft - 39W - 6400K - with Snap-On Reflector

Complete T5HO Strip Light Kit with Snap-On Reflector, 3ft / 39W

Buying a bare T5HO tube and then separately sourcing a ballast, reflector, and mounting hardware is more assembly than most propagation setups need. The Sunpack T5HO Strip Light ships as a complete kit -- lamp, electronic ballast, snap-on mirror reflector, hanging hardware, and power cord all included -- so it goes straight from the box to the bench.

At 39W in a 3ft housing, this size suits propagation trays, seedling flats, and herb shelves matched to that footprint. The super-slim profile fits under shelving and inside clone domes where a bulkier fixture would not.

Key Features & Benefits

• Complete kit out of the box — lamp, ballast, snap-on reflector, hanging hardware, and power cord all ship together, ready to install.
• Snap-on mirror-finish reflector — redirects light that would otherwise scatter upward or sideways back down toward the canopy.
• 6400K full-spectrum T5HO lamp — included lamp favors compact, vigorous vegetative growth in seedlings, cuttings, and herbs.
• Electronic ballast — drives the lamp without the hum or flicker of an older magnetic ballast.
• Super-slim housing — fits under shelving and inside clone domes where a bulkier fixture would not.

Who Should Use This

Home growers and small propagation operations who want a ready-to-install T5HO fixture rather than sourcing a lamp, ballast, and reflector separately will get the most from this kit, particularly in under-shelf or clone-dome setups where space is tight.

About Sunpack

Sunpack's T5HO strip light kits share the same reflector and ballast design across every length in the line, so growers scaling up a propagation area can add fixtures without relearning a new setup.

Frequently Asked Questions

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

Yes, the reflector snaps on and off without tools, but leaving it attached is recommended since it noticeably increases the light reaching the canopy for no added power cost. Removing it only makes sense in unusually tight clearances where the reflector itself does not fit.

How do I replace the T5HO lamp once it dims?

The included lamp is a standard T5HO tube of the matching length, so it can be swapped for any compatible replacement tube once output declines, typically after 10,000-12,000 hours of use. No special tools are needed for the swap.

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

Yes, this fixture uses the standard Sunpack link cord connector, so it can be chained with other Sunpack T5HO and LED strip lights using link cords sold separately. Up to 8 units can run from a single outlet in one chain.

Is this wattage enough for flowering crops?

T5HO fixtures like this one are best suited to propagation, seed starting, and vegetative-stage growth where their broad, diffuse output performs well. For flowering crops that need higher intensity and more red-spectrum light, a dedicated LED or HID system is generally the better fit at that stage.
