High Pressure Sodium Lights Energy Consumption

They lose roughly 15 of their heat emissions which adds to their inefficiency.

High pressure sodium lights energy consumption.

Depends on your definition of a lot. Hps light costs differ based on the particular fixtures but are cheap compared to leds. High efficacy that is easily comparable to led lights. For high pressure lights it is 50 to 140.

High pressure sodium fixtures are not as energy efficiency as leds. The downside is that there are very few options outside the narrow range to choose from. High pressure sodium lights tend to have a lifespan averaging 24 000 hours. 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.

Sodium based lights require a warmup period. 50 w up to 1000 w. The reason that they are used is that they give a lot of light for the amount of power they use. Low and high pressure sodium lights are well known for their warm yellow glow cct values around 2200k.

High pressure sodium lights range between 5 10. High pressure lights are slightly less efficient. Initially leds will cost more to install but the energy savings low maintenance costs and lifespan puts them ahead of hps lights. They are available in a range of wattage.

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. Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient. Hps vs led energy savings. 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. 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. Additionally while leds do not produce radiant heat with the light that is emitted there is heat generated by the diode itself. The efficacy in lumens per watt for low pressure sodium lights is 60 to 150.

Two varieties of such lamps exist. When it comes to high pressure sodium lights vs led energy consumption led lighting has become the industry standard. 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. Led area lights are top of the line bulbs.
