SunBlaster High Output 36-LED 6400K 18W Strip Light, 18"

Fan-Free LED Strip Light for Compact Grow Spaces, 18in

Fan-cooled grow lights add moving parts that eventually wear out, and an external power adapter is one more piece of hardware to route and protect from moisture near a growing area. SunBlaster's High Output LED Strip Light avoids both: a self-cooling LED array sheds heat without a fan, and a self-ballasted design plugs directly into a standard outlet with no separate adapter to manage.

At 18 inches and 36 LEDs, this fixture suits a single shelf setup, with a built-in rocker switch and a 12-inch link cord for wiring to a neighboring unit.

Key Features & Benefits

• Self-Cooling LED Array — sheds heat passively, with no fan to eventually wear out or draw extra power.
• Self-Ballasted Design — plugs directly into a standard outlet, with no external adapter to route or protect.
• 6400K Full-Spectrum Output — cool-leaning light suited to vegetative growth and propagation stages.
• Rated for 50,000 Hours — a long service life compared to a fluorescent lamp needing periodic replacement.
• Links Up to Eight Fixtures — connect multiple strips from a single power cord to scale across shelves or racks.

Who Should Use This High Output Strip Light

This strip light fits growers who want a fan-free, low-maintenance fixture for seed starting, propagation, or supplemental lighting in a small space. It scales from a single 12-inch strip on a windowsill shelf up to a full bench of linked 4-foot fixtures for a commercial propagation area.

About SunBlaster

SunBlaster designs LED and fluorescent grow lighting from its base in Langley, British Columbia, selling both complete fixtures and standalone strip lights through horticultural distributors. The High Output line replaces the fan-cooled designs common in earlier LED fixtures with a passively cooled array, cutting down on the moving parts that typically fail first.

Frequently Asked Questions

What does self-cooling mean for this fixture?

Self-cooling means the LED array and its housing are designed to dissipate heat passively through the fixture body, without a fan pulling air across the components. That removes a moving part that would otherwise be the first thing to wear out or fail in a fixture run continuously for months at a time.

How do I connect multiple High Output strips together?

Up to eight High Output strip lights can be linked from a single power cord, so a grower can scale from one fixture to a full bench without running a separate outlet to each unit. Larger fixtures in the line include their own power cord and rocker switch, while the smaller sizes share cabling with a paired unit.

Why choose a self-ballasted fixture over one with an external adapter?

A self-ballasted fixture has its driver built into the strip itself, so there's no separate power brick to find space for, keep dry, or lose track of when moving fixtures around. The tradeoff is that the fixture itself runs slightly warmer than a design with the driver housed remotely, which is part of why the self-cooling array matters here.

What's the difference between the LED counts on each size?

Longer fixtures use more individual LEDs spaced across the strip, from 24 LEDs on the 12-inch model up to 96 on the 4-foot version, so lumen output scales with fixture length rather than concentrating more diodes into a short strip. That keeps light spread evenly along the whole fixture instead of creating hot spots.

How long will the LEDs last before they need replacing?

The fixture is rated for approximately 50,000 hours of use, which works out to several years of typical daily run time before output degrades meaningfully. Unlike a fluorescent lamp, the LED array in this fixture isn't designed to be swapped separately, so the whole strip is the replaceable unit.
