HID System Anatomy

1. HID Lamp – the light source. Also referred to as a grow light or bulb. 2. Ballast – an electrical device that supplies power to the HID lamps. The ballast takes the available voltage from your electrical outlet and ramps it up to provide a high-voltage pulse to start the lamp. It then regulates…

Lamp-Ballast Compatibility

What is LBC? Lamp/ballast compatibility (LBC) is a phrase used to describe the working relationship between a ballast and a HID lamp. In most cases this phrase often refers to electronic ballasts operating HID lamps. LBC is a hot topic because electronic ballasts can fail to consistently operate HID lamps, mainly Metal Halide lamps. Many…

Lamp Replacement Guide

When growing indoors, light intensity and spectrum become even more important. The quantity and quality of light are the most critical factors associated with successful plant growth. Regular lamp replacement is essential. Lamp Type Optimal Growth Average Growth Maintenance Growth HPS 9-10 months 11-12 months 13-16 months Metal Halide 6-8 months 9-10 months 10-12 months…

Effects of Overdriving

Setting your ballast to overdrive can produce frequencies that are damaging to your lamp. Damaging frequencies distort the arc stream in a lamp’s arc tube. These pictures show what happens inside the lamp’s arc tube when your ballast is in overdrive mode. This distortion causes cracking and may rupture the arc tube and destroy your…

Lighting Maintenance

Taking care of your grow lights and e-Ballasts means that they will operate longer and perform better. Regular grow lamp maintenance is an essential component of indoor plant growing.

Lamp Operating Positions

Lamps must be used in their specified operating positions in order to maximize lamp performance and longevity. Incorrect operating positions may also create the possibility of a lamp rupture. It is imperative that users adhere to the specified operating positions and fixture requirements. The following chart shows the correct lamp operating positions based on the…

Lamp Dimension Key

Maximum Overall Length (M.O.L.): MOL is measured from the end of the lamp base to the top of the outer jacket. Light Center Length (L.C.L.): The distance from the light center to a specified reference point on the lamp. Diameter: The diameter is the maximum diameter of the glass bulb. Maximum Overall Length (M.O.L.): The…

Bulb Shapes

Note: Bulb size or diameter (maximum) is expressed in an eighth of an inch (1/8″) for one unit. For instance, a BT56 bulb is 56 eighths of an inch in diameter, or 7 inches in diameter. See ANSI C79.1 for a complete details on bulb shapes.
