18" T5HO Combo 6400K

SunBlaster’s 18" T5HO Combo 6400K is a fluorescent strip light and reflector package for propagation and compact growing areas. The 18-inch combo draws 17 W, includes an electronic ballast, a 6400 K full-spectrum T5HO lamp, and the NanoTech T5 Reflector to widen spread and minimize heat. Nominal size is 474 x 46 x 36 mm. The 6400 K lamp’s spectrum shows peaks near 435 nm (blue) and 615 nm (red), and it is rated for 10,000 hours. In practice, this length is paired with a standard 10 x 20 inch propagation tray, and SunBlaster sells it in Mini Greenhouse kits built around that footprint, giving an approximate single-tray coverage. Fixtures can be linked together (up to eight) via the supplied jumper plug for expanded areas.
