Indoor plant lights can shine when there is no sunlight. They allow you to prolong the growing season of plants, provide flowers, healthy vegetables and herbs throughout the year, and allow your seedlings to grow before planting outside. Because of the different spectrum, there are several kinds of growth lamps in the market, from simple incandescent lamp, fluorescent lamp to HID and LED lamp.
The following is the introduction of 1000W reflector HPS lamp
in HID lamp on the market.
HID lights are the brightest and most efficient, but the price is also high.
A 1000-watt HID lamp produces the same amount of light as 50 40-watt fluorescent lamps.
In the HID category, there are several types of bulbs: high-pressure sodium lamp, metal halide lamp, low-pressure sodium lamp and mercury vapor lamp. Indoor gardeners only need to worry about high-pressure sodium lamps or metal halide lamps. The most common specifications are 400 watts and 1,000 watts. A 400-watt light can provide enough light for a garden of about 15 square feet (1.4 square meters). A 1000W reflector HPS lamp can cover an area of about 4.5 square meters. For rapid growth, about 25 watts of HID lamps can be used for every 0.09 square meters.
1000W reflector HPS lamp is red and orange, which is the most suitable for flowering plants. It is also economical because its average life is twice as long as metal halide lamps. High-pressure sodium lamps produce up to 140 lumens per watt. Their main disadvantage is that they do not produce light in the blue spectrum. How long a growth lamp should be turned on depends on the plant and its needs. Most plants and vegetables need about 10 to 12 hours of light a day to grow. Plants that produce fruit or flowers take more time: up to 16 hours a day.
