Special Metal Halide lights created for horticultural now come with an enhanced red spectrum, the spectrum used by plants for producing fruit. The university studies reveal there is no evidence to support the commonly-held belief that the extra blue light from a metal halide is best for vegetative growth. Difference between High Pressure Sodium Grow Lights vs LED Grow Lights Now that you know what these lights are, here’s a closer look at the differences between High Pressure Sodium Grow Lights vs LED Grow Lights: Colour Temperature: The colour spectrum that the HPS Grow Lights offer is very narrow and limited. Metal halide lamps and high pressure sodium (HPS) bulbs fall into this category. Only high-pressure sodium and pulse-start metal halide fixtures have ignitors. The warmer 3000K light is a great way to simulate 3000K metal halide lamps like the Philips MHC100/U/M/3K or ALL high-pressure sodium lights. A metal halide bulb produces about 65-110 lumens of light per watt while a high pressure sodium bulb produces about 96-150 lumens of light per watt. Indoor grow specialists all over the world use blue-heavy metal halide lamps (MH) for vegetative growth and switch to red-heavy high pressure sodium (HPS) At Utah State University, Professor Bruce Bugbee recently published a paper on the subject, and his research on a variety of lights and manufacturers demonstrates that (A) HPS puts out considerably more photons per watt of input power than metal halides, and (B) that there is no evidence to support the assertion that increased blue in a metal halide leads to more vegetative growth than HPS. Lamp life is 6,000 to 15,000 hours (so more energy efficient but shorter bulb life as compared to Mercury Vapor). It greatly depends on the type and quality of the led too. Neither mercury vapor nor standard metal halide fixtures need ignitors to strike an arc through the lamp. Thread Tools. High Pressure Sodium lamps are the preferred light for supplemental greenhouse light. First off, HID lights last longer than Halogen. (adsbygoogle = window.adsbygoogle || []).push({}); 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. A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides (compounds of metals with bromine or iodine).It is a type of high-intensity discharge (HID) gas discharge lamp. The main difference between metal halide and high pressure sodium is that metal halide lamps have a high efficiency and color rendition of light whereas high pressure sodium lamps have a poor color rendering. These lamps are energy efficient and long lived. Metal Halide Lights Metal halide lights give off an intense, bluish-white light that plants respond to with healthy, vigorous growth. The bulbs in this family produce a large amount of lumens, which is why they’re used for public spaces, like stadiums. 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. Some points to ponder from my discussions with two university professors (Professor Bugbee at Utah State and Erik Runkle at Michigan State) who have studied horticulture and supplemental lighting for many years: • HPS is about twice as electrically efficient as metal halide. Selanjutnya, Metal Halides relatif rapuh dan ketika rusak memerlukan penanganan khusus, karena mengandung bahan berbahaya seperti merkuri. They have both a Metal Halide and a High Pressure Sodium filament in each light so they put off both the MH and the HPS light spectrum.

Metal halide lamps produce light in the white and blue spectrums, while high pressure sodium lamps produce light in the yellow, orange and red spectrums. // ]]> High Pressure Sodium bulbs have another benefit: a long usable bulb life, as long as two to five years, and they are very energy efficient with six times more light output per watt than an incandescent bulb. New User? When used alone throughout the plants’ life cycle, however, High Pressure Sodium causes plants to stretch and become leggy, with larger spacing between branches. The halogens can all react with metals to form metal halides according to the following equation: http://www.tomorrowsgarden.net/ I show running High Pressure Sodium Conversion Bulbs on a Metal Halide Ballast. Indoor gardening supply shops now have HID conversion bulbs so growers can have the benefit of both HPS and MH light. Thinking about a little indoor gardening this winter? Like Metal Halides, High Pressure Sodium lights are omnidirectional, which wastes light and makes them less efficient. HID lighting systems contain a properly matched transformer, capacitor and lamp, which is an inner arc tube with a chemical mixture. The apparent MH effect is likely caused by the amount of light, rather than the color of light.”. To plan a good indoor gardening system, it is important to learn about all the types of lighting available, and to research what lighting would work best for your purposes. • HPS is about twice as electrically efficient as metal halide. MH vs HPS. Metal halide lamps last about 15,000 hours, and HPS bulbs can last up to 24,000 hours. The HID lights that are most frequently used in growing plants indoors and in greenhouses are metal halides and high-pressure sodium (HPS). Plants will be stocky and strong, with dense green foliage. //
