SunBlaster T5HO 17W 6400K w/NanoTech Reflector, 18"

Compact 18-Inch T5HO Fixture With a Built-In Reflector, 17W

Small-scale propagation stations and open shelving often need a grow light that arrives ready to run rather than a bare lamp requiring a separately sourced ballast and reflector. SunBlaster's T5HO combo pairs a 6400K high-output fluorescent lamp with an electronic ballast, a power cord with an inline switch, and a NanoTech reflector molded into the fixture housing, so the whole assembly powers on and directs light down onto the canopy the moment it's unboxed.

At 17 watts and 18 inches, this is the smallest fixture in the T5HO combo line, sized for a single shelf, a small propagation station, or supplemental lighting in a tight space where a full-length fixture would overhang the growing area.

Key Features & Benefits

• 6400K High-Output T5HO Lamp — full-spectrum, blue-leaning output suited to vegetative growth and propagation stages.
• Built-In NanoTech Reflector — spreads light across the canopy without drawing any additional power from the ballast.
• Electronic Ballast Included — the fixture arrives pre-wired and ready to plug in, with no separate ballast to source.
• Inline Power Switch — the power cord includes a built-in switch for on/off control at the fixture.
• Mounting Clips Included — hang or mount the fixture directly above the growing area without extra hardware.

Who Should Use This T5HO Combo

This combo fits growers who want a self-contained fluorescent fixture rather than assembling a lamp, ballast, and reflector from separate parts. It works equally well for a hobbyist lighting a single shelf of seedlings and a commercial propagation area standardizing the same fixture across several benches.

About SunBlaster

SunBlaster, based in Langley, British Columbia, builds T5HO and CFL fluorescent lighting alongside LED strip lights and mounting accessories for indoor and greenhouse propagation. The T5HO combo line pairs the company's own reflector design with an electronic ballast in a single fixture, rather than leaving growers to match ballast and reflector hardware from separate sources.

Frequently Asked Questions

What does the NanoTech reflector do?

The NanoTech reflector is molded directly into the fixture housing, so it redirects light that would otherwise scatter to the sides back down onto the canopy. It works passively and draws no extra power from the ballast. No separate reflector hood or additional wiring is needed.

How do I link multiple T5HO combo fixtures together?

Up to eight T5HO combo fixtures can be connected end-to-end from a single power cord and outlet, letting growers scale lighting across several shelves or a wider bench without running a new cord to each unit. Each fixture keeps its own inline switch, so individual units can still be turned off separately.

Why choose a combo fixture instead of a separate ballast and lamp?

A combo fixture arrives pre-wired with the ballast, lamp, and reflector already matched to each other, so there's no compatibility guesswork between parts sourced from different places. It also cuts down on separate purchases and wiring steps for a new shelf or bench. The tradeoff is less flexibility to mix and match components later, which matters more to growers running highly customized lighting setups.

What does the 6400K rating mean?

6400K describes the lamp's color temperature: a cool, blue-leaning white similar in tone to overcast daylight. Growers typically favor this range for vegetative growth and propagation, where compact, sturdy growth matters more than the redder spectrum used for flowering. It's a standard rating shared across most T5HO and CFL grow lamps, not unique to this fixture.

Can I replace the lamp when it dims or burns out?

Yes, the T5HO lamp in this combo is a standard replaceable component, and SunBlaster sells matching T5HO 6400K replacement lamps sized to fit the same fixture length. Replacing the lamp on schedule keeps the ballast and reflector in service without buying an entirely new combo fixture.
