Interlux 400W HPS Double Ended Grow Lamp - 400 W

Double Ended HPS Light for Indoor Flowering Rooms - 400 W

Growers who want steady, red-weighted light for flowering need a lamp that matches their fixture and ballast. This double ended HPS lamp is built for high frequency electronic ballasts and 400W double-ended reflectors. Double ended HPS lamps are generally designed to hold output well over their working life, and a one-year warranty backs this one.

As a single 400 W lamp, it suits hobbyists, small tents and growers replacing one lamp in an existing double-ended fixture. Larger rooms use several lamps, one per fixture.
