PHOTOBIO T LED, 330W, 100-277V S4, (10' 208-240V Cord)

Slim Linear LED Toplight, 10' 208-240V Cord

A toplight mounted above a greenhouse canopy has to avoid blocking natural sunlight while still delivering enough supplemental light to matter, and a bulky fixture with a fan working overtime doesn't help either goal. The PHOTOBIO T 330W is a slim linear LED toplight built for greenhouse and indoor canopy lighting, using closed-loop heat-pipe cooling to run fan-free while its low profile minimizes shadowing of natural light in a greenhouse.

This configuration ships with 10' 208-240v cord. Includes a 10' 208-240V power cord, matched to commercial 208-240V circuits.

Key Features & Benefits

• 330W Slim Linear Toplight — closed-loop heat-pipe cooling moves heat away from the diodes without fans.
• Up to 858 µmol/s Photon Flux at 277V — 2.6 µmol/J efficacy for greenhouse and indoor canopy lighting.
• S4 Full-Spectrum LED — a tuned spectrum built to support vigorous growth and flowering.
• Auto-Adjusting 100-277V Input — the driver senses and adapts to facility voltage automatically.
• DLC Listed (H-3WMUH6G), IP65 Rated — qualifies for utility rebate programs in eligible regions and is sealed against water and dust.
• Communications-Tree Compatible — works with the PHOTOBIO AC Power Distribution Tree and DC Communications Tree for multi-fixture rooms.

Who Should Use the PHOTOBIO T 330W Fixture

This fixture fits greenhouse and indoor growers who want a slim, fan-free toplight that minimizes shadowing of natural light while supplementing canopy light, in rooms wired for a range of commercial voltages.

Electrical Installation Note

Consultation with a licensed electrician working alongside a qualified electrical engineer is recommended to confirm compliance with applicable electrical code and local inspection requirements before installation.

Frequently Asked Questions

How is this fixture cooled?

A closed-loop heat-pipe system moves heat away from the diodes without fans, which keeps the fixture running quietly and without moving parts to maintain. That fan-free design is part of what keeps the fixture's slim profile.

Is this fixture suited to greenhouse use?

Yes, its slim linear profile is designed to minimize shadowing of natural sunlight, which matters in a greenhouse where the fixture supplements daylight rather than replacing it. It also performs as a standalone canopy light in fully indoor rooms.

What voltage range does this fixture support?

An auto-adjusting 100-277V input range, with the driver sensing and adapting to facility voltage automatically. The specific cord included with each configuration still needs to match your facility's receptacle or wiring.

Can multiple fixtures be networked together?

Yes, via the PHOTOBIO AC Power Distribution Tree or DC Communications Tree. Either option lets a multi-fixture room share power distribution and control cabling instead of wiring each fixture as a separate run.

What is the warranty?

5 years, backed by Hydrofarm. Keep your purchase documentation on hand in case you need to reference the warranty.

What cord is included?

A 10' 208-240V power cord ships with this fixture. It's matched to commercial 208-240V circuits.
