Threshold Arc Lamp | 400 watt high pressure sodium lamps are designed to assist your indoor garden in reaching its full potential. Such a product is designed for longevity, and these HPS lights are generally more resistant against potential damage. A typical lamp is comprised of three parts; the reflector, the ballast, and also the socket. The socket cord is generally between ten and twelve inches long, and they are designed to hook into any hood system. The socket is straightforward to gather or dissemble as they are needed.
The reflector inside a high pressure sodium lamp is constructed from heavy duty, lightweight sheet metal. It is specially treated to resist rust. A reflector should certainly produce direct light which will improve the overall light output that comes from your hood assembly. A horizontal shaped deflector allows the reflection of light directly to the plants as a result of proper downward reflection. A quality reflector in HPS lights will contain twelve “bends” for only light distribution without leading to hot spots on the reflector. Such knowledge is essential to possess in order that a consumer learns how to pick a quality product.

HPS lights also include a ballast. The ballast is protected by component enclosure housing. The housing is constructed from extruded aluminum. Fins on the housing of the ballast allow heat to securely dissipate without air vents. A ballast, itself, is the idea the location where the heat dissipates coming from a permanent fixture. High pressure sodium lamps require specifically engineered ballasts due to the high amount of energy and electrical currents that they can use. However, these are remarkably power efficient for the power that they can do consume, and also the 400 watt bulb (i.e. Sylvania Lumalux 400W) has proven a trendy option among gardening enthusiasts. If the 400 watt bulb isn’t adequate for your requirements, then this bulbs come in a tremendously wide selection of wattages.
