YSeparate topic entirely but some time ago I postulated that low pressure sodium supplemented with low wattage LED lighting in the same fixture might be more efficient, or at least more economical than high pressure sodium. While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. Link below Ever wonder why street lights are orange? Moreover, HPS lights are modular so if one bulb in the set-up fails, it can be changed without replacing the entire system… the go-to choice for cultivating cannabis on a tight budget. I am not saying high pressure sodium illumination is not hideous, but at night the orange illumination is softer on the eyes than the illumination from a 5000K LED fixture. 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. I looked at some charts and found that High Pressure Sodium is more efficient than an LED bulb. Several other people have commented this as well. Let’s face it, many LED grow lights are expensive! I have seen some and the light looked very good, clean and white. Select the lamp wattage (lamp lumens) For each: Select the type of lamp (i.e. The cost, in this case would be $0.278 for one hour of usage if electricity is at the usage rate of 13.9 cents per kilowatt hour. It is the light itself, even the stretches of concrete road dimly illuminated under the light appear glaring. Incandescant, Fluorescent, etc.) Several other people have commented this as well. They lose roughly 15% of their heat emissions which adds to their inefficiency. 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. LEDs have a light spread of 180 degrees, and so more light is actually directed towards the subject in question. not the rest of the lighting infrastructure, such as the poles and wires.

Metal Halide lights have a long warm up time and can take 15-30 minutes to get to full power. Since the technology for this grow light has been around for so long, HPS lights are inexpensive to produce. Dimmable If white LEDs have never been invented or are still in its infancy now, these CMH lamps would have been the hot threat for HPS. The wider spectral output makes individual objects more discernible from each other, and IMO that's what matters. The cost, in this case would be $0.278 for one hour of usage if electricity is at the usage rate of 13.9 cents per kilowatt hour. This results in maximum efficiency, optimal yield, discrete operation, and greatly reduced energy costs. Warehouse lighting example. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. The lamp works by creating an electric arc through … Are LED street lights actually more efficient than High Pressure Sodium? Here are 5 truths about growing bigger yields with LED vs HPS grow lights. This article will weigh the pros and cons of light-emitting diode (LED) vs high-pressure sodium (HPS) lighting. Compared to an HPS light, the best LED grow lights might cost 3-10 times as much per unit of light produced. High Pressure Sodium lights have often been seen as the best grow light available for amateurs and professionals alike, and the key to their popularity is their incredible raw light output. The reigning champion of grow lights. You can support this channel on Patreon! High pressure sodium lights work by creating an electric arc through vaporized sodium metal, while additional materials and gases work to start the lamp and control the its color. There are just many applications where the up-front cost of switching to all LED would be too expensive, and low pressure sodium (LPS) is extremely efficient, nearly as good as the most efficient commercially available LED street lamps. Something else I thought I would mention here, I saw. You'll get a better answer if you point to the specific chart you're referring to. LEDs are an instant on and install off. Every 2 months you use your new LED lights pays for one of your new fixtures. Do you think the HPS can be dethroned? Indeed, high pressure sodium (HPS) lights are generally unmatched in terms of energy efficiency. High Pressure Sodium Lights Vs Led Cost. Low and High Pressure Sodium lights are the only light whose source efficiency compares to LEDs (values range between 50 and 160 lumens/watt for LPS and slightly less for HPS). I will take a white LED street light over a sodium or mercury vapor lamp any day. No, I know LED street lighting can cause glare because of the intense point-like light sources of the bare emitters, but this is not what I was talking about. Turning On and Off. Why bother buying a kind of light if half of what it emits goes the opposite direction of where you want it to go? They offer excellent color rendering (up to 96 CRI), are very efficient (90-110 l/W, about the same as most current LED street lamps), and the advantage is they have a lower initial cost for higher wattage applications than LED. Since both types of lamp are HID, they are designed to produce generous amounts of light, or lumens.
