{"title":"400W HPS Lamps","description":"\u003cp\u003eA 400W HPS lamp is a sensible choice for small tents around 60x60 to 80x80 cm, or as extra light in a corner of a larger room. It runs cooler than higher wattages, which makes the climate easier to manage in a compact space. Right now you'll find the GE Current Lucalox 400W bulb here, a classic high-pressure sodium lamp with a warm spectrum for flowering. Use it with a matching 400W ballast and an E40 reflector.
