high pressure sodium lamp price

High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas. They are commonly used in public parking lots, roadways, and other security areas.

A big driver behind their use is their high efficiency – around 100 lumens per Watt (when measured for photopic lighting conditions) Some higher-power lamps (>600 Watt) can achieve efficacies of around 150 lumens per watt.

It is very difficult to get any material which is free from corrosion in presence of sodium vapor in high temperature and pressure. This is the main difficulty of producing high-pressure sodium lamp.

In 1959, the development of polycrystalline alumina (PCA) opened a new path to introduce the high-pressure sodium vapor Lamp, as this material is very rarely affected by high pressure and temperature sodium vapor. The first lamp with 400 W, 42000 initial lumens and 6000-hour life first came in the market in 1965. But afterward, some improvements made this lamp with 50000 initial lumens with 24000 hours at 10 hours per start. We can get a lamp that has 2.4times the lumens output of its mercury counterpart with same rated life span.

Diagram of High Pressure Sodium Lamp

It has an inner PCA arc tube that is filled with xenon gas. This xenon gas is used for starting purpose of the lamp as ionization potential of xenon gas is lowest among all other inert gases used for this purpose. In addition to xenon gas sodium mercury amalgam is present in this arc tube, too. In each end, back wound and coated tungsten electrodes are mounted. To seal the tube monolithic seal is used instead of niobium end cap.

The arc tube is inserted into a heat resistant outer bulb. It is supported by an end clamp that is floating. This end clamp permits the entire structure to expand and contract without distorting.

The space between the tube and the bulb is a vacuum space. This vacuum space is needed to insulate heat from the arc tube because it is necessary to keep the arc tube at required temperature to sustain arc during normal operation. High pressure sodium lamphas very small diameter (3/8 inch). So there is no enough space to provide any starting electrode in the arc tube. So a higher voltage is required to initiate the arc. A ballast with igniter is used for this purpose. High voltageis fed to the lamp from the ballast by using the phenomenon of superimposing a low energy high voltage pulse.

Generally a typical pulse has a peak voltage of 2500V and it has durability for only 1 microsecond only. This high voltage pulse makes the xenon gas ionized sufficiently. Then it initiates and maintains the xenon arc. The initial arc has sky blue color. Amalgam used in the reservoir formed inside the arc tube. It is in the back of one of the electrodes. It is normally vaporized during lamp operation. As the xenon arc has started temperature of arc tube is increased which first vaporizes mercury and the lamp start glowing with bluish white color. This color represents the effect of the xenon and mercury mixture at excitation. Gradually the temperature again rises, and sodium becomes vaporized lastly and becomes excited, a low pressure monochromatic yellow sodium spectrum results. During the period of sodium spectral line becomes at 589 nm. With temperature the sodium pressure increases from 0.02 atm in the monochromatic discharge to over 1 atm in the final steady state, broad spectrum condition. Also presence of excited mercury and xenon gives bluish effect to the lamp radiation and finally pleasant golden bright light comes out.

Lighting can often be overlooked when it comes to re-decorating, because it is often thought of as a utilitarian rather than a key factor in the overall décor of your room. But, when chosen correctly, your lighting can become a true focal point and is guaranteed to take your home design to the next level!

We have put together the ultimate light buying guide to help you to choose the correct lighting for each room in your home, with the perfect balance of style and substance. Because choosing the correct lighting is not as simple as you may initially think…

Wofi Viso Pendant Designer Bar Light


The first step to choosing the correct lights for your home is to work out how much light you need in a room to keep it well lit.

In 2010, the way we measure bulb brightness changed. Bulb brightness used to be referenced in wattage (W), but now it is referenced in lumen (LM).

Each room in your home will require a different number of lumens in order to be lit adequately. To work this out, you can check an illumination chart which will show you the ideal number of footcandles or lux you will need for a certain task.

A footcandle = the amount of light on a surface created by one candela that is a foot away from the surface.

A lux = the amount of light on a surface created by one candela that is a metre away from the surface.

One candela = the light from one standard candle.

If you are using feet, look at the number of footcandles. One footcandle is equal to 1 lumen per square foot. Multiply the number of footcandles by the square foot in the room and this will tell you how many lumens are required. 

If you are using metres, look at the number of lux. One lux is equal to 1 lumen per square metre. Multiply the number of lux by the square metres in the room and this will tell you how many lumens are required. 

Find our illumination chart below:

And if you’d like to see how the kelvins will affect your room, you can use this useful tool from, which shows how the colour temperature will transform the lighting in this kitchen space.


Now that you know how many lumens are requires in each room, the next step is to understand the three main uses of lighting. Don’t make the common mistake of thinking that one type of lighting will suffice for an entire room. Lighting works much better when used in layers. So, it’s important that you put together a lighting plan for each room, and a successful lighting plan should include three uses of lighting: ambient, task and accent.

Ambient Lighting

Ambient lighting is the main light source in the room and will usually be your starting point. This lighting will determine the overall mood within the room, for example a living room will have a warmer and more relaxing tone than that of a workspace. Ambient lighting tends to come from recessed lighting or wall light fixtures within the room.

Task Lighting

Task lighting is focused light that is used when tasks will be carried out in the room. A good example of this is a desk lamp, which will often be adjustable in order to illuminate areas that you need the most to help you carry out tasks. 

Another example is vanity lighting above a mirror and under-cabinet lighting in a kitchen.

Accent Lighting

Accent lighting is the most decorative type of lighting in the room, its used to highlight focal features such as wall art, bookshelves and fireplaces. Accent lighting could also be a focal point itself if you go for a statement piece. For example, our Wofi Indigo Ceiling Light Often floodlights, track lights, picture lights and wall-mounted fixings are used.


Getting creative with your lighting will mean mixing different types of lights together, so its important that you know the different options available on the market.

Ceiling lights

Almost every room will have ceiling lights because they usually provide the ambient lighting within the room. The two main types of ceiling lights are pendent and flush lighting. Pendant lights hang down from the ceiling usually by a cord or chain whereas flush lights have little or no gap between the light fitting and the ceiling. There’s a vast array available on the market from strikingly stylish to the functional, and here at Lighting Style, we like to mix the two together!

Floor Lamps

Floor lamps are often pigeonholed to the ambient light category and also in the task lighting category, this is because they are perfect for adding extra illumination in rooms that need it but they can also be the perfect adjustable overhead lamp to add focused light in required areas. They are also ideal for adding smaller amounts of light in a room when needed, for example in the living room on an evening when you don’t want the main lights on, but you do want a small amount of light.

Table Lamps

Table lamps are extremely versatile as they can be placed anywhere and usually create the task lighting within your room. They’re often adaptable to allow for versatile use, for example dimmable for a bedside table or adjustable for desk work. You could go for an extravagant design and use it as part of the room décor too, the options are endless!

Wall Lights

Wall lighting does it all. They can create gorgeous accent and highlight focal

points within the room beautifully. They can help illuminate hallways and larger

rooms and add to the ambience within the room. They’re ideal outside lighting, or

when placed strategically they’re great task lights for focused reading.

Spotlights enhance visibility where you need it, they’re ideal task lighting. They are either made of several spotlights along a metal bar or a singular bright light that sits close to the ceiling. They can usually be adjusted to point in the correct direction for your needs.

Now that you know the different types of lights available, it’s time to choose the right bulbs! Many of our lights come with LED’s already installed, but some you will need to get the bulbs additionally if stated in the product description.

There are three main types of blubs; LED’s, CFL and Halogen. Incandescent bulbs are now being phased out.

LED’s: LED bulbs are a great eco-efficient option. They typically use 90% less energy than an incandescent bulb. They last the longest, they’re cheap to run and produce very little heat. Here at Lighting-Style we only stock LED’s (we think they’re fab!). Plus they are extremely versatile, meaning that during the manufacturing process they can be integrated straight into the frame of a light to create stunning strips of light, as seen in the image below:

CFL: Short for compact fluorescent lamp, CFL’s are the most common type of energy-saving bulb. They typically use 60-80% less energy than an incandescent bulb. They are a cheaper alternative to LED’s but they do take a while to reach their optimum brightness which can be frustrating when you need the light to complete a task.

Halogen: The cheapest of the three, halogen bulbs are dimmable but typically have a shorter lifespan. They use 20-30% less energy than an incandescent bulb.

At Lighting Style, we only offer LED’s. You can see our range below:

Choose the bulbs that best suits your lamp or light shade. Our decorative light bulbs are another great way of making a statement in your home, we have various lights where the bulb will still be visible, for example our Wofi Richael Pendant Light, so pairing with a statement bulb will make the light all the more stunning.

The cap, which is the base of the bulb, holds the bulb firmly in place while providing an electrical connection between the light and the bulb. In the above images you can see the cap type referenced under each image (E27, E14, G9, GU10 etc…). You will need to know the cap type of your light or lamp before purchasing a bulb for it.This can be found in all of our product descriptions, most typically an E27 or E14 bulb will be suitable, just be sure to check!

The kelvin scale

The next step is to understand the kelvin scale. The kelvin scale is used to describe the warmth or coolness of the light. The colour spectrum ranges from the yellow-based colour to the blue-based colour. As an example, people often prefer the yellow-based colours in a living room, and the blue-based colour in a utility, but there’s no right or wrong it’s ultimately down to your personal preference.

See our kelvin scale below.

light kelvin temperature scale

Many of our LED lights can be temperature adjusted to suit your desired kelvins throughout the day. However, most of our LED lights are set at a default of 3000K, which gives a nice cosy feel to the room.

Once again just be sure to check the product description to see what the temperature is set to and also if it can be adjusted. 


While the layout of the room is down to your individual taste, there are some tips that we can give you that will work well for each room in your home.

Firstly, you need to decide on what mood you would like to create in each room and what type of lights will complement your personal style and the current design in your home.

Entryway Lighting

This is arguably the most important area to ensure a grand entrance and a good first impression is created. Start with a dramatic statement light such as a chandelier overhead light, and then complement this with a floor lamp.

Kitchen Lighting

Kitchens are very busy spaces, where food preparation will take place. This means it must be illuminated well, especially in areas where you will be carrying out food preparation. Check out our blog post on kitchen lighting ideas for more inspiration!

You should start with general ambient lighting, we would suggest a pendant light or track lighting if you have a feature in the room, such as a kitchen island or breakfast bar, but if not recessed lighting will work well too.

You will also require task-orientated lighting where food preparation will take place, this can be provided by the addition of an under-cabinet lighting system. This will ensure that the kitchen is illuminated well enough in the areas that really need it, avoiding shadows being cast over knives and other potentially dangerous tools.

Dining Room Lighting

A common mistake with the dining room is hanging a chandelier over the table and thinking that is enough light for the whole room. It’s important to remember to create layers. A statement light over the dining room table is a great start, a chandelier or a pendant light will look stunning. Check out our blog post on dining room lighting ideas for more inspiration!

You then need to balance this, a great way to achieve this is to have recessed or track lighting, this will create the layers and avoid the room looking flat.

Living Room Lighting

The most multi-functional room in the home, the living room is an all-purpose area where you will watch TV, read books, chat with friends and family or do homework. This means the lighting in this room needs more diversity, to reflect the diverse tasks that are carried out in the room.

For general ambience, a pendant light or flush ceiling light overhead will create a good amount of light for the room. Then add floor and table lamps or sconces situated in task areas to provide more direct light, for example, if you have an armchair you like to read in or an area on the sofa where you tend to carry out tasks.

Bathroom Lighting

Vanity lighting is perfect for the bathroom, if you have a mirror in the bathroom then they are perfectly situated at the top of this. Not only will this add to the décor of the room, but it also adds the perfect amount of lighting in front of the mirror to help you when you’re getting ready in the morning. 

For the general ambient lighting in the room, wall scones and recessed lighting will work a treat, and it’s always a good idea to get dimmable lights in the bathroom so that you can dim them when you would like to relax in the bathtub.

Bedroom Lighting

The perfect place to unwind and revive yourself, it’s important to have soft ambient lighting in the bedroom. A decorative semi-flush ceiling light that can be dimmed will give the perfect ornamental feature while providing you with soft ambient lighting. Complement this with accent lighting on the walls to give an extra luxurious feel. Many people also like to read in bed, so either an adjustable table lamp to go on your bedside table or a wall-mounted reading lamp is essential.

Home Office Lighting

You’ll need this area to focus on work, so this room needs function-orientated lighting. For the general ambience, recessed lighting or a flush overhead light will provide the main illumination for the room. Then you’ll need a desk lamp that can be adjusted in your main work area, and perhaps a floor lamp in dark corners or situated over the top of seating areas within the room.
