High Pressure Sodium Lights Energy Consumption

In fact led bulbs use between 40 75 less electricity than a hps fixture.

High pressure sodium lights energy consumption.

The reason that they are used is that they give a lot of light for the amount of power they use. The downside is that there are very few options outside the narrow range to choose from. Depends on your definition of a lot. Additionally while leds do not produce radiant heat with the light that is emitted there is heat generated by the diode itself.

50 w up to 1000 w. They lose roughly 15 of their heat emissions which adds to their inefficiency. For high pressure lights it is 50 to 140. High pressure sodium lights tend to have a lifespan averaging 24 000 hours.

Low pressure sodium lights produce the greatest amount of light per watt of energy consumed. High pressure lights are slightly less efficient. Hps light costs differ based on the particular fixtures but are cheap compared to leds. Led area lights are top of the line bulbs.

High efficacy that is easily comparable to led lights. Low and high pressure sodium lights are well known for their warm yellow glow cct values around 2200k. I also like the soft light they produce. When it comes to high pressure sodium lights vs led energy consumption led lighting has become the industry standard.

Blue light 450 nm is a higher energy light compared to red 635 nm causing an increase in energy consumption with an increasing percentage of blue light. This can take up to 20 minutes in some cases meaning your lights must be turned on at least 20 minutes prior to use to ensure maximum illumination. A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. The efficacy in lumens per watt for low pressure sodium lights is 60 to 150.

High pressure sodium fixtures are not as energy efficiency as leds. Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient. Hps vs led energy savings. High pressure sodium lights range between 5 10.

Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. Initially leds will cost more to install but the energy savings low maintenance costs and lifespan puts them ahead of hps lights. 100 watt high pressure sodium 1 100 138 150 watt high pressure sodium 1 150 188 200 watt high pressure sodium 1 200 250 250 watt high pressure sodium 1 250 295 400 watt high pressure sodium 1 400 465 40 watt mercury vapor 1 40 50 50 watt mercury vapor 1 50 74 75 watt mercury vapor 1 75 93 100 watt mercury vapor 1 100 125 175 watt mercury vapor.
