Sun White Spectrum

This all-natural light spectrum boosts healthy growth rates for house plants, microgreens, flowers, fruits and more. By mimicking sunlight conditions with a high CRI of 95, the Sun White Spectrum will make your garden look more vivid and it will be easier to detect pests and deficiencies before they spread. This truly full-spectrum light extends beyond the traditional PAR range (400-700 nm) to include far-red wavelengths that increase photosynthesis rates via the Emerson Effect.

 

Additional Features

Bypass the Hassle
This ballast bypass LED grow lamp works with existing T5 fluorescent light fixtures by bypassing the ballast and wiring the lamp holders (tombstones) to a single end. Without the need for a ballast, these universal voltage 120-277V lamps do not flicker, buzz or experience longevity issues. *Requires bypassing the ballast during installation. Requires non-shunted lamp holders (tombstones). Please refer to the T5 LED GROW LIGHT BYPASS BALLAST INSTRUCTIONS VIDEO below for detailed installation steps.

Sustainable Horticultural Lighting
Replaces 32W T8/40W T12 4FT fluorescent lamps. Uses 45% less energy, greatly reducing heat output, HVAC costs and the need for more vertical space.

Plant Centric Design
Designed specifically for horticulture use with a 100% more effective spectrum for plant growth and a high PBAR (280-800nm) output and efficacy.

ClearSync Film Technology
The ClearSync protective film improves water resistance and prevents glass shattering without sacrificing photon output.

Long Lifetime & Guarantee
Features an exceptional 30,000-hour lifetime and a 3-year warranty. Active Grow is locally based in Seattle, WA providing same day response and friendly support.

Certified Safe
All lamp components and manufacturing processes meet the highest industry safety standards.

Great cable kit.
Size: 20FT Black & 20FT Red, Size: 20FT Black & 20FT Red
Great heavy duty cable. Good thick feeling insulation that looks the real deal. Wire is soft enough to route easily without too much resistance. Appreciate it coming with the lugs and heat shrink instead of you having to source extras. Seems to be truly copper as listed. Great deal for the length if so. Worked for what I needed on my UTV.

Cheap price for the cable and terminal ends with heat shrink.
Size: 20FT Black & 20FT Red
Good 6 gauge wire, jacket seems sturdy and like it won't crack easily over time like some wire. Comes with all the connectors shown too so you don't need to find end ring connections to terminate the ends. Just need a punch or crimp tool for the terminals but if you already have that then just cut your wire length and add the ends for battery cable.

Outboard thermostat
Works fine. A little pricey but better to buy the best than risk a cheap failure and destroy your engine like i did once.
