Many growers are switching to LEDs but is there still an argument for buying HPS?.. LED floodlights vs High Pressure Sodium floodlights Efficiency High Pressure Sodium floodlights come closer to rivalling LED floodlights than halogen and metal halide. Yield A brand new, top-of-the-line 600W HPS grow light could cost $200, but I could easily end up paying $800 or more for an equivalent LED grow light. I was pretty amazed just how lanky they grew. HPS grow lights have a shorter shelf life in comparison to LED lights. This tends to lead to gardeners in the US growing under 1000W bulbs, whereas their European counterparts lean towards 600W or even 400W bulbs. LED Vs HPS And MH Grow Lights – The Ultimate Comparison. HID Cost Comparison BLACK DOG LED PLATINUM XL VS. 1000W HID:TOTAL COST OF OWNERSHIP ANALYSIS Have you ever wondered what the total cost of setting up and running a traditional High Intensity Discharge (HID) garden is compared to a garden set up with the newest Light-Emitting Diode (LED) technology? While those of HID grow lights are iPower, Apollo Horticulture, Sun system, Vivosun, Yield Lab, Eye Hortilux, Digilux, Ushio and many more. In Depth comparison for high efficiency Horticulture Lamps. Here's a half-pound (trimmed) Sensi Star I grew (along with others) in my old 1200w vertical HPS set-up. If you are planning for obsolescence and want the greatest yield ROI within 1-2-year time frame, choose CMH. This is a side by side comparison covering a span of five years. To make this informed decision, you need to understand every facet of your environment, since every grow is different. LED vs. The Grow Closet. 1.1 What Is Available On The Market. It’s not easy to pick a winner in our discussion about HID vs LED Grow Lights. That said, Both can provide decent yield, but be careful with LED and make sure you use a high-quality light, which is m small-scale growers should stick to HPS lighting if they want to save money, with double-ended bulbs being the best option for higher wattage fixtures, say 1000 W. more pricey than an HPS light. In the early days of LED grow lighting, there were marketers out there who espoused the positives of the technology and offered it at an appealing price point. The dilemma is rightly justified; selecting the right grow-light is an immense task. HPS grow lights are typically a hefty setup more suited to long-term grows; HPS lighting solutions need replacement every 1-2 years; Breaking It Down. Comparing Efficiency, output and performance for HLG 650R vs HLG 550 Rspec Commercial LED Grow Lamp. At first, LEDs seemed to fail to accurately pinpoint and perform the in necessary section of the light spectrum. HPS lights are more standardized among manufacturers, making it a bit easier to comparison shop. Larger Yield and Higher Quality versus HID If you're thinking of making the move to LED grow lights and you've been shopping around, you've probably noticed that Black Dog LED lights are more expensive than traditional HID lights. Many growers, however, state they find no difference in yield, and some claim HPS bulbs' yellow lighting stimulates bud production, leading to higher yields when used during the flowering stage. LED grow lights vs HPS defined. Numerous attractive ad campaigns make the situation even more complicated, with […] LED HPS comparison. HPS light setups have a cheaper initial start-up cost, but the price gap between comparable HPS and LED grow has become much smaller as LED grow light setups have become more and more affordable each year. (More LED grow journals can be found here.) Thread starter GanjaMclover69; Start date Apr 1, 2020; Tags effeciency hps and led; LED or HPS LED Votes: 83 71.6% HPS Votes: 33 28.4% Total voters 116; Grow 3: 1000w HID (400w CMH + 600w HPS) No Yield Data (Powder Mildew took over) Grow 4: 1000w HID (400w CMH + 600w HPS) Total yield 325g or .33 grams/watt Grow 5: 580w (400w CMH + Mars II 400w) Total yield 245g or .42 grams/watt Grow 6: 540w LED (3x Mars II 400/180w models) Total yield 308g or .57 grams/watt My grow closet measures 2′ x 8′. Many LED manufacturers will show how quickly they can hit a good ROI with LEDs and use 1.85 μmol/ J as their HPS comparison. Table of Contents. LED Vs HPS yield result from our UK grow diary As an example, our grow UK grow diary achieved twice the grams per watt with a MIGRO 400 compared to an optimised 600W HPS system. LED vs HPS Grow Lights: In 2018 Since the introduction of the Light Emitting Diode or LED in to grow technology, there has been arguments and aversion to the modern alternative. HPS Vs CMH Vs LED cost comparison The break even point to recover the additional cost in LED is now only 6 months due to the increase in LED efficiency and reduction in cost for LED fixtures. A good way to get a true comparison between the cost of LED vs. traditional lighting is to look at the cost per µmol delivered, as the outputs from one manufacturer to another can differ. HPS lights emit light by sending a pulse of high-voltage energy through a pressurized quartz tube filled with vaporized sodium, along with other elements such as xenon and mercury. Below is an example to demonstrate: 1000w HPS DE Fixture w/ 2100 µmol output at $550* = $0.26/µmol. Our comparison will take you through a look at how LED grow lights vs. HPS grow lights affect yield, as well as how their heat output differs, and what energy efficiency you can expect.
