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.

High pressure sodium lights energy consumption.

Hps light costs differ based on the particular fixtures but are cheap compared to leds. Two varieties of such lamps exist. Initially leds will cost more to install but the energy savings low maintenance costs and lifespan puts them ahead of hps lights. High pressure sodium fixtures are not as energy efficiency as leds.

High efficacy that is easily comparable to led lights. High pressure lights are slightly less efficient. 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. Low pressure sodium lights produce the greatest amount of light per watt of energy consumed.

High pressure sodium lights range between 5 10. The efficacy in lumens per watt for low pressure sodium lights is 60 to 150. Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient. 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.

Additionally while leds do not produce radiant heat with the light that is emitted there is heat generated by the diode itself. When it comes to high pressure sodium lights vs led energy consumption led lighting has become the industry standard. High pressure sodium lights tend to have a lifespan averaging 24 000 hours. Sodium based lights require a warmup period.

Although high pressure sodium lamps emit visible light across a slightly more broad spectrum than low pressure sodium lamps they are still very limited. Led area lights are top of the line bulbs. 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. 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.

The downside is that there are very few options outside the narrow range to choose from. For high pressure lights it is 50 to 140. They lose roughly 15 of their heat emissions which adds to their inefficiency. In fact led bulbs use between 40 75 less electricity than a hps fixture.

Hps vs led energy savings. Depends on your definition of a lot. They are available in a range of wattage. 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.
