SunBlaster LED Strip Light - 48in - 48W - 5150 Lumen - 6400K

Fanless LED Strip Light with Self-Cooling Technology, 48in

Cooling fans on a grow light fixture are an added moving part that can fail, and they add operating noise many growers would rather avoid near living or working spaces. SunBlaster's Self-Cooling Technology (SCT) dissipates heat from the LED array passively, without fans or other active cooling hardware, so the fixture runs quieter and has one less component that can wear out over time.

At 48in and 48W with a 120-degree beam angle, this fixture spreads even, wall-to-wall coverage across a full shelf or tent bay, fitting growers who want broad, low-maintenance lighting rather than a narrow focused beam.

Key Features & Benefits

• Passive Self-Cooling Technology (SCT) — dissipates heat from the LED array without fans or other active cooling parts, cutting operating noise and removing a common point of mechanical failure.
• 6400K daylight-balanced output — a blue-rich color temperature suited to compact vegetative growth, propagation, seedlings, and leafy crops.
• 120-degree beam angle — spreads light evenly across the full fixture length instead of concentrating it in a narrow strip, reducing hot spots under the fixture's center.
• Dense LED array — a high LED count per strip delivers consistent light distribution from one end of the fixture to the other.
• Daisy-chainable design — connects to other SunBlaster strip lights with a standard link cord, so growers can extend coverage without separate wiring runs.

Who Should Use This

This fixture fits indoor growers who want quiet, low-maintenance lighting for propagation, vegetative growth, and supplemental lighting in tents, shelving units, and grow rooms. The fanless design is especially useful in noise-sensitive spaces such as living areas, offices, or bedrooms where a fan-cooled fixture would be noticeable.

About SunBlaster

SunBlaster Lighting builds T5HO and LED grow lighting for home and commercial growers, alongside propagation domes, trays, and growlight garden kits. Self-Cooling Technology is SunBlaster's passive thermal design for its LED strip platform, built to move heat away from the LED array without fans or other active cooling hardware.

Frequently Asked Questions

What does Self-Cooling Technology do differently than a standard heatsink?

SCT is a passive heat-dissipation design built around SunBlaster's LED array, rather than a generic aluminum heatsink bolted onto the fixture. Because fewer moving parts are involved, the LEDs run without fan noise or the upkeep a fan assembly eventually needs.

How does this fixture compare to SunBlaster's Prismatic Lens LED strip?

This SCT fixture uses a 120-degree beam for broad, even coverage across a full shelf, while the Prismatic Lens strip narrows its beam to 90 degrees for higher intensity directly under the fixture. Choose the SCT strip for wide, low-maintenance coverage and the Prismatic Lens strip when concentrated light on a narrower footprint matters more.

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

Yes, SunBlaster strip lights share a common link cord connector, so SCT and Prismatic Lens fixtures can be chained together. Keep the combined wattage of a chained run within your outlet and circuit rating.

Is a fanless design actually cooler than a fan-cooled fixture?

Passive cooling relies on heat spreading across the fixture body rather than being pushed away by moving air, so it prioritizes reliability and quiet operation over active heat removal. SunBlaster sizes the SCT heat path to each fixture's wattage so it can run continuously at its rated output without a fan.

What growing stages is this fixture suited for?

The 6400K spectrum and 120-degree beam suit propagation, vegetative growth, and general supplemental lighting rather than one specialized stage. It works as a standalone light source over seedling trays and shelving, or as added coverage alongside other fixtures.
