Dimmable HPS VS LED High Pressure Sodium What is a High Pressure Sodium Light: High Pressure Sodium (HPS) lights, similar to LPS lights, are a specific type of gas-discharge light (also known as a High Intensity Discharge, HID or arc light). While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. Something else I thought I would mention here, I saw. Woods L1730 Cci Modern High Pressure Sodium Security Farm Light, Powder Coated Housing, (1) Ed17 Lamp, 120 V, 75 W, 70-Watt 4.1 out of 5 stars 23 $62.94 $ 62 . However, there is exactly one other type of lighting that beats HPS in that category, and that is Light Emitting Diode (LED). 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. 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. In fact most of the LED fixtures going up right now are. What's that light cost you? Ceramic metal halide (CMH) is another good option for street lighting. Led vs high pressure sodium led vs high pressure sodium led vs high pressure sodium led vs hps cost comparison you. You'll get a better answer if you point to the specific chart you're referring to. Oh and yes, some are failing already. 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). 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 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. 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 got two Sylvania ET-23.5 mogul based 100w ceramic metal halide lamps. They have a rated life of 24,000 hours. Between fluorescent, LEDs, and high-pressure sodium (HPS), the great wide world of grow lights can get confusing. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. In the 550m2 area, the cost per kg of cucumber is $1.30 for the high-pressure sodium lamp alone, $1.45 for the sodium lamp and single-row LED lamp, $1.72 for the sodium lamp and 2-row LED, and the profit cost ratio is 2.31, 2.07 and 1.74 respectively. Several other people have commented this as well. I do not remember noticing a glare problem from them while driving, so I think it has to do with more than just color temperature. LED claim to fame is you can get a reasonably white light source for much less energy than a white metal halide or mercury vapor (?). By running a 2000 watt load for 1 hour, 2 kilowatt hours of electricity have been consumed.
