SUNPACK LED Strip Light - 18in - 18W - 2,091 Lumen - 6400K

Long-Life LED Strip Light with Built-In Reflector, 18in / 18W

A T5HO tube loses output gradually from the day it is installed and needs replacing roughly every year, which adds an ongoing cost that LED lighting mostly avoids. The Sunpack LED Strip Light delivers 6400K full-spectrum output through a built-in reflector, rated for 50,000 hours of service -- several years of regular use before output declines meaningfully.

At 18W and 2,091 lumens, this 18in size suits propagation trays, seedling racks, and shelf gardens matched to that footprint, and it can be daisy-chained with other Sunpack LED strip lights of any size using link cords sold separately.

Key Features & Benefits

• 2,091 lumens at 18W — delivers substantial light output relative to the power it draws, versus an equivalent fluorescent tube.
• 6400K full-spectrum output — favors compact, vigorous vegetative growth in seedlings, herbs, and leafy crops.
• Integrated reflector — directs light down toward the canopy instead of letting it scatter, at no extra power cost.
• 50,000-hour rated lifespan — spans several years of regular use before output declines enough to warrant replacement, unlike an annual T5HO tube swap.

Who Should Use This

Home growers, herb gardeners, and indoor cultivators who want a long-lived, low-maintenance light for propagation trays, seedling racks, or shelf gardens will get the most from this fixture, especially compared with the yearly tube replacement a T5HO setup needs.

About Sunpack

Sunpack positions its LED strip lights as the longer-lived alternative to its T5HO fixtures, sharing link cords, hanging clips, and stand hardware across both lighting lines.

Frequently Asked Questions

How does the integrated reflector improve results?

The built-in reflector redirects light that would otherwise scatter upward or sideways back down toward the canopy, concentrating more of the fixture's output where plants can use it. That improves effective light delivery at the canopy for the same power draw, compared with a strip light that has no reflector.

Can I daisy-chain this with other Sunpack LED strip lights of different sizes?

Yes, all sizes in the Sunpack LED strip light line use the same link cord connector, so different wattages and lengths can be mixed in one chain. Always check that the combined wattage of every linked unit stays within your outlet's circuit rating.

What does a 50,000-hour rated life mean in practical terms?

Run on a 16-hour daily light cycle, 50,000 hours works out to roughly 8.5 years before the LEDs reach their rated 70% output threshold. Even on a continuous 24-hour schedule that is still well over 5 years, versus the roughly annual tube swap a T5HO fixture needs.

Is the 6400K spectrum right for every plant and growth stage?

6400K suits leafy crops, herbs, seedlings, and vegetative-stage growth well. For flowering and fruiting crops, many growers prefer a warmer spectrum or a broad-spectrum fixture once plants move into that stage.
