This means your power bill is reduced significantly through simply swapping metal halides with LEDs. Metal halide lights are omnidirectional. LEDs last much longer, more energy efficient and require less maintenance. I will certainly comeback. Moreover, the most common compound is sodium iodide. LED Vs the Competition. They produce steady light without flicker. Why? Metal Halide lights are omnidirectional meaning they emit light for 360 degrees. Metal halides are perhaps the best source of high CRI white light on the market. The use of LED lights greatly saves electricity costs. For this reason in many applications (such as a sporting stadium) metal halide lamps must be changed out prior to the end of their useful life. Then a few years later LED grow lights started gaining a lot of traction in the cannabis grow light market. Both metal halides and LEDs are considered to be more energy-efficient than incandescent lamps. The first practical use of LEDs was in circuit boards for computers. The heat emissions from Metal Halides are also much greater than LEDs, which means less energy is directed towards the actual illumination. On the … A Metal halide (MH) lamp is an electrical lamp or bulb that produces light by creating an electric arc, combining a gaseous mixture of vaporized mercury and various metal compounds (Bromine or Iodine). – Winner LED Note: Foot Candle ratings are very application specific and vary case by case so relative performance is difficult to generally quantify. you will need about 10,000 lumens. A type of High-Intensity Discharge (HID) lamp, this light is typically used in high bay lighting fixtures in warehouses, parking lots, and hangars because of their high lumen output. $129.99 $ 129. In fact, after a review of the facts above, it should be apparent that the lifespan of a metal halide depreciates rapidly. But there are other factors to consider. LEDs are solid state lights (SSLs) that are difficult to damage with physical shocks. These include the following: 1. Your Options for an Industrial LED Lighting Solution, Distribution Center Warehouse LED Retrofit Case Study. We are talking about LED lighting of course! Typically, the type of metal halide light bulb used in high bay applications has a rated life of around 20,000 hours. You can select what information you would like to receive. In some cases dimming can also cause the light to prematurely expire. Careful coordination of lighting locations, net tracks, heating systems, and the wicket can help eliminate shadows and facilitate achievement of even light distribution. LED Metal Halide Equivalent Cost comparison. – Winner LED Note: recent advances in LEDs will likely improve their droop qualities. 4.3 out of 5 stars 37. Hi There! Metal halide lights are very efficient compared to incandescent lights (75-100 lumens/watt source efficiency). Accessories: LEDs require far fewer accessory lamp parts.2. More Buying Choices $82.47 (2 used & new offers) DragonLight 120W Super Bright Corn LED Light Bulb(400 Watt Metal … That is, if one uses 40 x 70 W metal halides in a row, then 57 LED down lights would be required. Traditionally growers used Metal Halide (MH) bulbs during the VEG cycle due to the high percentage (23%) of blue in the MH spectrum. GRANT. Metal Halide lights also experience efficiency losses as the device ages and additional current is required to achieve the same lighting output. Reply. Metal halide bulbs require regular relamping and ballast replacement in addition to the labor cost to monitor and replace aging or expired lights several times within the typical lifespan of a single LED. There are pros and cons to both options, so let’s look at the differences between the two so that you can decide which will be best for you and your grow setup. Efficiency losses are greater than LEDs and the degradation time shorter in the case of Metal Halides. However, LED lights go beyond that. Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The main difference here is the depreciation rate of the available lumens. Generally speaking metal halide lights are less efficient when run at less than full power. LEDs last longer than any light source commercially available on the market. The greater the lumens, the brighter or more intense the light. Based on the cost savings, efficiency and quality – LEDs are superior light sources for almost every business. Many metal halide lamps used in warehouses and sports facilities take 15-20 minutes just to reach their normal operating temperature. CRI for LED is highly dependent on the particular light in question. LED Lights: MaxLite Wall Packs Replace 100-250 Watt Metal Halide; Energy Efficient Lighting: What Are Light Distribution Patterns? By comparison, LED lights are directional. They lose out to LEDs principally because their system efficiency is much lower (<30 lumens/watt) due to all of the losses associated with omnidirectional light output and the need to redirect it to a desired area. In many cases, and depending on the particular mix of metal halides, they have a very high color temperature (up to 5500K). In this case it would be better to use stronger unit like metal halide light or stronger 3 W each led bulbs in 300 W fixture. LEDs use about half the energy of metal halides to deliver the same amount of light, and they last seven times longer, on average. Metal halide lights for sporting stadiums might take 15-20 minutes to arrive at maximum brightness. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange. Metal halide lights are 3-5 times as efficient as incandescent bulbs and produce a much higher quality light. Minus 40 Degrees Celsius (and they will turn on instantaneously). The specifications from HID grow light manufacturers have more consistency than LEDs. 100 Degrees Celsius. really well written article. For larger metal halides, such as those that illuminate fulfillment centers or heavy machinery lots, it can take up to 30 minutes to warm up and reach maximum illumination. To replace it with the same intensity LED, just look for one that rates around 2300 lumens. That’s theoretically. It is an immediate cost savings that cannot be ignored. 4. They are available in color temperatures as low as 3000K. Select options View Details. Furthermore, Metal Halides are relatively fragile and when broken require special handling, because they contain hazardous materials such as mercury. When a light expert measures light using a light meter, they get the readings in … Encased in a thick glass, metal halides operate when an electrical current passes through a combination of metal and halogen elements, generating gas that creates visible light. For a metal halide light, the initial light output is extremely high. Ceramic metal halide lights are famous for their sunlight-like quality. They’re More Standardized. This is not the case for high pressure sodium, LED and induction alternatives. Best to use a bulb and keep those fixtures. Electrical Pros of LED Lights We can also replace the 100-watt metal halide with a 40-watt LED lamp. Color: LEDs can be designed to generate the entire spectrum of visible light colors without having to use the traditional color filters required by traditional lighting solutions.3. Additionally, LED fixtures One thought on “LED Grow Lights vs Ceramic Metal Halide Grow Lights: Which is Better?” Hillary February 24, 2019 at 8:08 am My best choice would be LED Grow Lights only because i am a very busy grower and LED lights get the job done for me when i cannot manage all too much. Both technologies produce a very high quality light. The ultimate purpose of the device is to emit light, not heat. LED. Common applications for metal halide lighting includes large sport facilities like stadiums or hockey rinks as well as high bay lighting for warehouses and large indoor spaces. We understand that, for a business, what it comes down to is cost savings. When current passes through the semiconductor material the device emits visible light. Metal halide lights get less efficient when run at less than full operating power. Metal Halide lights emit UV radiation and require a filter built into the bulb to keep these emissions from being radiated into the atmosphere. LEDs have virtually no warm-up time. Different light types (LED, halogen, metal halide) have different luminous efficacy, so we should ask the sports lighting contractors before buying. Hello There. One of the main issues with metal halide bulbs is that they tend to lose 50% of their light output half way through their typical lifespan. Note: sometimes metal halide lights need to be changed out before the end of their useful life to preempt serious degradation effects like color changes or cycling. Omnidirectional lights produce light in 360 degrees. High Pressure Sodium vs LED - What’s The Difference Between High Pressure Sodium and LED Lights. In fact, it is not uncommon to see lumens depreciate by 20% within the first six months of use. A 20,000-lumen LED and a 455-watt metal halide produce roughly the same amount of light, but a typical LED fixture uses less than 200 watts to do so. Below, our experts here at Action Services Group define the differences between the two types of lighting and explain why LEDs are superior in almost every way. LED Products Power Conversion Color Temperature; EverWatt 150W LED Corn Light Bulb: From 1000W MH to 150W LED: 5000 K : RuggedGrade 150 Watt E39 LED Bulb: From 1000W MH to 150W LED: 4000K: Ustellar 100W LED Work Light (1000W MH Equivalent) From 1000W MH to 100W LED: 5000K: How many lumens does a 1000 watt LED … 2. The equivalent LED light should have more or less the same lumen output to maintain the same brightness and installation height. HOST: Paul Keeler Replacing the lighting in homes, factories, parking lots, stadiums, gas stations and other places with LED lights will reduce annual energy use (kWh) costs by at least 60%. Our LED outdoor light fixtures are available in either 4000 Kelvin or 5000 Kelvin options. As of mid-2018 this would be regarded as a highly efficient sports light. Both technologies produce a very high quality light. In fact, after six months you will already need to start looking into replacing them. Spectrum comparison. New LEDs can last 50,000 to 100,000 hours or more. This means you will need to replace them less often than you would have to replace a metal halide. The typical lifespan for a metal halide bulb, by comparison, is 12-30% as long at best (generally between 6,000 and 15,000 hours). Well here’s a head-to-head comparison of the two followed by an in-depth discussion of each technology in turn. LEDs can be extremely small (less than 2mm in some cases) and they can be scaled to a much larger size. Nowadays, Metal Halide lights are being replaced by LED lights for industrial use. 2. This means they consume less energy to produce the same, if not better, lighting than that of a metal halide. First, let’s take a look at the lamp and fixture efficiency of a metal halide. For decades, metal halide lights were said to be one of the best lighting options around. They emit mostly blue light, which encourages vigorous growth of foliage. FREE Shipping by Amazon. Where LEDs really shine, however, is in their system efficiency (the amount of light that actually reaches the target area after all losses are accounted for). As long as you keep calculating and using the lumens per watt method, you can always replace the 1500W metal halide light with more LED lights. LED lights can replace metal halide sports lights and provide better light. The two different technologies are entirely different methods of producing light. LED stands for Light Emitting Diode. In some circumstances this could be beneficial, however, it is a generally a bad thing as heat losses represent energy inefficiencies. Metal halide bulbs contain metals that are evaporated into inert gas within the glass casing while LEDs are a solid state semiconductor technology. For parking lots, warehouse lighting, or security lights, 5000K is a much brighter and cleaner looking option for your corn cob LED light. Similarly, metal halide lights have a far shorter lifespan than LED bulbs. At one time, they were prized for their energy efficiency and long life.
