Similar to how MH lights have halides along with the primary gas, here you would find a mixture of sodium vapor and mercury which adds to the reddish tint of the light. Mercury Vapor, High Pressure Sodium, Quartz Metal Halide, Pulse Start Quartz Metal Halide, and Ceramic Metal Halide. Metal halide bulbs, sometimes shortened to just “MH” and high pressure sodium bulbs, sometimes shortened to simply “HPS”, are in a family called High Intensity Discharge bulbs, or “HID” for short. Moreover, the most common compound is sodium iodide. Most of the times, the metal halides are compounds containing bromine and iodine as the halide component. That said, a very broad spectrum of CRI values is available ranging generally from 65-95. Why are bulbs not interchangeable? Low pressure Sodium bulbs have a higher lumen output and longer life, they also give off less glare. The higher the wattage, the higher the hood can be placed, therefore increasing the available light footprint. The biggest being that of energy efficiency as the lights really consume very little electricity – and in the long-run pay off for themselves. A good quality HPS lamp will give you the same amount of lumens per Watt as an LED. - sezer66 / Shutterstock .

One is the size off the fixture itself, probably twice the size and easily 5 times the weight of a standard 500watt halogen work light due to the ballast. PRODUCTS BRIEF: HID lamps require metal halide ballasts or high pressure sodium ballasts for metal halide flood lights & hps flood lights, Magnetic ballasts kits include high pressure sodium ballasts or metal halide ballasts, Ignitor (Starter), Capacitor and HID bulbs. Metal halide bulbs, high-pressure sodium bulbs and mercury lamps make up the family of high-intensity-discharge (HID) lighting. The HID lights that are most frequently used in growing plants indoors and in greenhouses are metal halides and high-pressure sodium (HPS). Common metal halide to LED replacements: CRI for LED is dependent on the particular light in question. Metal halides are usually screwed into a reflector or hood to create even more light for the plants. Rates Type: Lamps: Number: Usage : The Dark Sky Society (DSS) is based on Long Island, NY. What is also interesting is that although metal halide lights are known for having high outputs of blue light, comparatively speaking, they actually do not create a discernible increase in vegetative growth. They emit mostly blue light, which encourages vigorous growth of foliage. by Garrett Rudolph August 1, 2014. written by Greg James August 1, 2014. The bulbs in this family produce a large amount of lumens, which is why they’re used for public spaces, like stadiums. its the same low pressure soduims came out back in the 40 with street lights and hps came out in the 60 for street lights is light tuning up a honda. HPS light costs differ based on the particular fixtures, but are cheap compared to LEDs. Enter the number of lights in use; Select how long the lamps are in use (or click to enter your own; enter hours on per year). TDegenhart. Sodium is best used for grow lights as it produces a red/orange light spectrum that helps plants bloom. Home Cultivation Metal halide vs. high-pressure sodium: An age-old question for cannabis growers. Of course, with each inch raised, the lumens emitted will have a diminishing effect . High-Pressure Sodium grow lights, just like Metal Halides, carry some Noble gases inside them. thats and the longer life is why they are used on Street lighting a lot. See the lamp catalog for more information. 600-Watt High-Pressure Sodium and Metal Halide Dimmable Digital Grow Light Lamp Ballasts (2-Pack) 20 in. The reason both are commonly found in grow rooms – especially marijuana grow rooms – is because there has been a long-standing belief that metal halides are best for the early vegetative stages of growth, and HPS are more effective for flowering. Metal halide vs. high-pressure sodium: An age-old question for cannabis growers . Like Metal Halides, High Pressure Sodium lights are omnidirectional, which wastes light and makes them less efficient. Similar to how MH lights have halides along with the primary gas, here you would find a mixture of sodium vapor and mercury which adds to the reddish tint of the light. The primary gas here is usually Xenon. Do they require different voltages to operate on? The HID lighting category includes metal halide (MH) and high pressure sodium (HPS) lights. High pressure sodium grow lights produce up to 40% more lumens per watt than metal halide lights, and this then leads to much higher yields when marijuana is flowering. RE: High Pressure Sodium vs. Metal Halide Squid Lights vs. Halogen Although Floodzilla and others like it are bright as ****, there are 2 minor problems with Metal Halide or High Pressure Sodium. The comparison above between High Pressure Sodium grow lights vs LED grow lights clearly indicates that the LED grow lights have a significant advantage when compared to HPS lights. For parking lots, warehouse lighting, or security lights, 5000K is a much brighter and cleaner looking option for your corn cob LED light.
