High Pressure Sodium Lights Energy Consumption

They are available in a range of wattage.

High pressure sodium lights energy consumption.

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. Two varieties of such lamps exist. 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.

The downside is that there are very few options outside the narrow range to choose from. 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. Depends on your definition of a lot. The efficacy in lumens per watt for low pressure sodium lights is 60 to 150.

Initially leds will cost more to install but the energy savings low maintenance costs and lifespan puts them ahead of hps lights. They lose roughly 15 of their heat emissions which adds to their inefficiency. 50 w up to 1000 w. Hps light costs differ based on the particular fixtures but are cheap compared to leds.

Low pressure sodium lights produce the greatest amount of light per watt of energy consumed. Additionally while leds do not produce radiant heat with the light that is emitted there is heat generated by the diode itself. Hps vs led energy savings. High pressure sodium lights range between 5 10.

Although high pressure sodium lamps emit visible light across a slightly more broad spectrum than low pressure sodium lamps they are still very limited. In fact led bulbs use between 40 75 less electricity than a hps fixture. High pressure sodium lights tend to have a lifespan averaging 24 000 hours. Led area lights are top of the line bulbs.

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. For high pressure lights it is 50 to 140. High pressure sodium fixtures are not as energy efficiency as leds. 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.

Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient. High efficacy that is easily comparable to led 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. The reason that they are used is that they give a lot of light for the amount of power they use.
