I believe it's there to remove impurities from within the outer glass envelope that would otherwise attack the arctube
The abbreviations are CFL - Compact Fluorescent Lamp, MHL - Metal Halide Lamp, HPMV - High Pressure Mercury Vapor, and one more is HPS - High Pressure Sodium lamp
From Wikipedia, high pressure sodium lamps use xenon, whilst low pressure ones use neon with a small amount of argon. See entry for 'sodium vapor lamps'
Sodium lamps can be dimmed but we shall have to look at the effect of low voltage on lamps
yes No Rafe, it will not. Remember when you tried it.
The bulb should be in the red end of the light spectrum. One HID lamp is the high pressure sodium lamp.
HPSV stands for High Pressure Sodium Vapor lamp. It is a type of high-intensity discharge (HID) lamp commonly used for outdoor lighting, street lighting, and agricultural applications due to its high energy efficiency and long lifespan. HPSV lamps produce a warm white or yellowish light and are known for their ability to provide good visibility and color rendering.
The High pressure sodium grow lights kits usually contain a ballast, a reflector, a lamp, a power cord and plug. But, the items may vary by the brands of kits you purchase.
High pressure sodium lamps are beneficial for outdoor lighting because they are energy-efficient, have a long lifespan, provide a bright and consistent light output, and are cost-effective in the long run.
You can generally determine if a halophane light is metal halide or high pressure sodium by looking at the color of the light it emits. Metal halide lights produce a white or bluish-white light, while high pressure sodium lights emit a yellowish-orange light. Additionally, you can refer to the manufacturer's specifications or labels on the light fixture for more information.
SON stands for high-pressure sodium. It is a type of lighting technology that uses a sodium vapor lamp to produce light. SON lighting is often used in outdoor and street lighting applications due to its high energy efficiency and long lifespan.
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all
Yes, all high pressure sodium fixtures require a ballast to operate the fixture's lamp. Most of these industrial fixtures come with a multi tap primary on the ballast so that they can be used on multiple voltages.
