A Grow Light consists of a lamp, a socket assembly, a ballast, and a reflector. Choose Metal Halide Grow Lights Halide Grow Lights, HPS Grow Lights, Dual MH/HPS Grow Lights or a Fluorescent Grow Lights system depending on your needs. You can purchase a fully assembled grow light system or purchase components to build a custom growYou may aslo want to consider a Grow Light Lift and a Light Mover to make your set up more efficient.

When should I use a Metal Halide Plant Grow Light? provides a balanced light spectrum closest to natural light. is excellent for rapid foliage growth and plants can be grown from start to finish using metal halide plant grow lights. Choose metal halide as a primary light source if little or no natural sunlight is available.

Super Metal Halide Grow Light Bulbs provide 12% more light output than Standard Metal Halide Lamps, but must be installed in a horizontal position only. Click here to shop Super Metal Halide Grow Light Bulbs When should I use HPS Plant Grow Lights? HPS, High Pressure Sodium, Grow Lights are 10-15% more energy efficient than Metal Halide but HPS does not have a balanced spectrum. HPS emits an orange/yellow light similar to the sun's spectrum in the mid day. HPS is best used as supplemental light and is particularly good at promoting

They are best for growing seedlings or providing supplemental light. Grow Lights and LED wattage Grow Light should I use? Optimal wattage depends on several factors including the

size of the growing area and the type of plants. Plants that require more light (i.e. tomatoes), need a higher wattage system. How high above the tops of my plants should I hang my grow lights? Hang your grow light high enough so your plants don't burn but low enough to maximize light exposure. To increase light coverage for a larger area, raise the light. For plants requiring very intense light, keep the lights as close to the plants as possible. Hanger to make it easy to adjust the heights of your grow light. Mover to increase the area of light coverage How long should I run my Grow Light? Most plants grow well with up to 12 hours of light a day. Long day plants may require up to 16 hours. Adjust the run length according to how your plants react. Click here to shop professional quality grow light How often should I replace my Grow Light Bulb? Replace Grow Light Bulbs before theyHPS lamps should be replaced every 2 to 2 1/2 years.

should be replaced at least once every year. After one year (12-14 hours a day) of use, MH lamps put out around 65% to 70% of the initial lumen output. 1 year most HPS lamps still give about 85% to 90% of the initial light output. Note: It is impossible to see with the naked eye if a lamp is dimmer or has lost a good percent of its initial life.

Hortilux lamps offer up to 25% bluer light than a standard HPS. This boosts green vegetative growth, and builds stronger stems. Warm Deluxe lamps offer up to 25% more red spectrum than standard MH lamps. This helps with flowering and fruiting in plants. lamps provide more lumens than standard HID lamps. Enhanced Performance HPS Grow Light Bulbs or Super What Grow Light Reflector should I buy?

Horizontal Grow Light Reflectors are the most common reflectors used for plant lighting. They do an excellent job concentrating the light in a downward direction, giving your plants intenseNote: Glass is optional on most horizontal hoods, and is required on MH systems for UL listing. Modern society requires outdoor lighting for a variety of needs, including safety and commerce. IDA recognizes this but advocates that any required lighting be used wisely. To minimize the harmful effects of light pollution, lighting should The illustration below provides an easy visual guide to understand the differences between unacceptable, unshielded light fixtures and those fully shielded fixtures that minimize skyglow, glare and light trespass. Are you looking for dark sky friendly lighting fixtures? Search our Fixture Seal of Approval database. Most people are familiar with incandescent or compact fluorescent blubs for indoor lighting, but outdoor lighting usually makes use of different, more industrial, sources of light.

Common light sources include low-pressure sodium (“LPS”), high-pressure sodium (“HPS”), metal halide and light emitting diodes (“LEDs”). LPS is very energy efficient, but emits only a narrow spectrum of pumpkin-colored light that some find to be undesirable. Yet, LPS is an excellent choice for lighting near astronomical observatories and in some environmentally sensitive areas. HPS is commonly used for street lighting in many cities. Although it still emits an orange-colored light, its coloring is more “true to life” than that of LPS. In areas where it’s necessary to use white light, two common choices are metal halide and LEDs. One of the advantages of LED lighting is that it can be dimmed. Thus, instead of always lighting an empty street or parking lot at full brightness, LEDs can be turned down, or even off, when they aren’t needed and then brought back to full brightness as necessary. This feature both saves on energy and reduces light pollution during the night.

Because of their reported long life and energy efficiency, LEDs are rapidly coming into widespread use, replacing the existing lighting in many cities. However, there are important issues to consider when making such a conversion. See our LED Practical Guide for more information. As the illustration above, it is crucial to have fully shielded lighting, but we now know that the color of light is also very important. Both LED and metal halide fixtures contain large amounts of blue light in their spectrum. Because blue light brightens the night sky more than any other color of light, it’s important to minimize the amount emitted. Exposure to blue light at night has also been shown to harm human health and endanger wildlife. IDA recommends using lighting that has a color temperature of no more than 3000 Kelvins. Lighting with lower color temperatures has less blue in its spectrum and is referred to as being “warm.” Higher color temperature sources of light are rich in blue light.
