What is a fragrance lamp

The Catalytic Lamp was originally designed to disinfect the air in hospitals throughout France.

Once Louis Pasteur proved that tiny organisms invisible to the naked eye existed, the race was on in France to end the spread of germs and disease. In 1898, a Pharmacist named Maurice Berger picked up the challenge and invented the catalytic lamp.

He came up with the ground-breaking idea of using catalytic combustion to purify the air, and once he proved his theory, the Fragrance lamp became a household fixture in the homes of the aristocracy.

Homes, hospitals, and similar facilities have used the catalytic process to purify the air in enclosed spaces for over 100 years and the simple yet very effective process is the same today as it was in 1898

The Fragrance Lamp won the French Invention of the Year award in 1901, Awarded the ISO 11014-1 for product safety and excellence, Won the Lyon Superior Award Received the Paris Commodity Award six times

It also won the Roman Market Product Award in Italy in 1906 The Exposition International d 'Economie Manager God Award was given in 1912 and in 1938, the Fragrance Lamp received the National Scientific Research and Development Gold Award in Atlanta USA

One of the biggest benefits of a fragrance lamp is the use of the disinfecting action of heating isopropyl alcohol to purify the air by breaking down the impurities on a molecular level. It collects and destroys bacteria and foul odors, and increases the oxygen level.

The addition of fragrance oils gives the added benefit of the lamp being an ideal home fragrance product and beautiful gift

Ashleigh & Burwood have taken the original technology, tweaked and refined it to create what we believe is the best system out there and the laboratory results prove it


How do they work

The Fragrance Lamp works via catalytic combustion. When the platinum catalyst present on the stone part of the wick assembly is heated, this creates a catalytic reaction with the Lamp Fragrance and oxygen. This reaction is self-sustaining while there is constant fuel and oxygen supply. The liquid in the Lamp Fragrance is drawn up the cotton wick into the porous ceramic stone, where the catalysis takes place, oxidising some of the liquid and releasing the rest into the air along with the fragrance. The heated liquid rises into the air, and through convection currents is diffused quickly throughout the surrounding air. This technology is particularly effective at ensuring the fragranced liquid is emitted in ultra-fine particles which rise quickly and distribute rapidly, far smaller than droplets produced by a spray, or standard evaporation, and at a far greater rate.

How do I use it

For the ultimate ambience in the home, use your Fragrance Lamp by simply placing this on a stable and spill-resistance surface, fill the Lamp with your favourite Ashleigh & Burwood Lamp Fragrance, light the stone for a few minutes and then blow out the flame which in turn releases the scent. 


Parts of the lamp

The Crown covers the hot stone to prevent accidental contact. Various designs are available.
The Snuffer-cap covers the catalytic stone. This prevents fragrance from evaporating when the Lamp is not in use and blocking the stone with fragrance particles. It is also used to cover the hot stone to turn the Lamp off.
The Retainer is a small metal clip that holds the stone, collar and wick together. You should never remove this clip.
The Stone is a special porous ceramic material coated in platinum and other rare metals.
The Collar supports the stone and secures the wick in place.
The Wick carries fragrance from the body to the stone.
The Assembly is a group name for the wick, collar, stone and retainer.
The Neck is a metal crimp attached to the Lamp Body which supports the Assembly.
The Body is the main part of the Lamp that holds the Fragrance.


What size lamp should I use

For the average 1200sqft (110sqm) home a small lamp will be more than sufficient and works in an area of 200-250sqft (18-22sqm). For larger homes or largen open plan spaces, a large lamp is best and will cover up to 450 sqft (40sqm)


How often & for how long should it be used

We would recommend using your Lamp for 20-30 minutes at a time. We do not advise using your Lamp for longer than 45 minutes at a time as this can cause damage to the wick. If you’d like to use your Lamp for longer periods, we recommend using the Lamp for 30 minutes, snuffing it out and leaving it to re-prime for 30 minutes before lighting again. This cycle of 30 minutes on and 30 minutes off can be repeated as frequently as you’d like, however, we wouldn’t normally suggest using more than twice a day.


Changing Fragrance

If you wish to change Lamp Fragrance, remove the fully cooled stone/wick assembly, lifting it by the metal retainer, and place it on a spill-resistant surface. Carefully pour remaining liquid from your Fragrance Lamp back into the original Lamp Fragrance bottle, using the funnel provided. Allow the wick to air-dry, the refill the Lamp with your new fragrance and reinsert the wick ready for priming.


How long will a lamp last?

The Lamp will last indefinitely as long as the body or neck is not damaged. The wick/stone may need replacing as it wears out from use, however if used exclusively with Ashleigh & Burwood’s Lamp Fragrance and the instructions are followed, then each wick will last for around 250 uses. We are still testing stones that have passed 300 uses and they are working at their optimum level.


I’ve children and pets – is it safe

Yes, provided you follow the safety instructions and keep your Lamp out of reach, so that there is no risk of the Lamp being knocked over or touched. Always place your Lamp on a flat stable surface. Remember that the stone is hot when in use. Always ensure the crown is on the Lamp when it is in use to prevent accidental contact with the hot stone.


The Fragrance is strong – can I “turn it down”

Fragrance Lamps are incredibly effective at fragrancing the air and you will find that the fragrance lingers for several hours in the room after the Lamp has been stopped. If you feel that it is the fragrance itself which is too strong for your liking, then it is possible to dilute down one of our Lamp Fragrances, using the Neutral (unfragranced) variety. You can mix in any ratio you like until you find the level which best suits you. For smaller rooms, you may also consider using for a shorter period of time.


The stone won’t light or get hot

Use this method if you have the following issues:

  • Your wick won’t light
  • Your wick won’t get hot
  • Your wick won’t remain lit for 2-3 minutes
  • You’re not receiving a good fragrance throw

If you’re experiencing the above issues, your wick could be blocked.

  1. Take your stone/wick assembly out of your Lamp and put into a ceramic bowl/cup. Never pull the wick out by the stone, always hold the collar and remove the whole stone/wick assembly in one piece. Always ensure that the Stone is completely cooled before touching it and be careful when removing the wick as it will be soaked with Lamp Fragrance.
  2. Pour your Lamp Fragrance into your bowl/cup and fill until 2-3 cm full.
  3. Cover with cling film and put into a cool dark place. Leave for 24 hours.
  4. Place the wick back into your Lamp, bearing in mind the rope part of the wick will be soaked in Lamp Fragrance, so again be careful with any dripping.
  5. Replace the snuffer cap and leave for 10 minutes.
  6. After 10 minutes light the wick. Please use caution as initially the flame will be quite high (up to 3 inches). Use your Lamp again as normal!


I need a new wick

Lamp Fragrance

What is it made from?

The basis of the Lamp Fragrance, and the important fuel which keeps the catalytic process working, is an alcohol called isopropyl alcohol. A very common alcohol, it is the same form of alcohol which is commonly used in hand sanitisers for example. The other ingredients are distilled water, and the fragrance compound itself.


Is it safe to breathe in?

When the Lamp is used in accordance with the instructions, the amount of isopropyl alcohol (IPA) released into the air is well within the safe limits for adults, children and pets. The majority of the IPA is burned during the catalytic combustion process which breaks it down into simply water and carbon dioxide, and the remaining IPA that is released into the air diffuses very rapidly. The OSHA (Occupational Safety and Health Administration) limit for exposure to IPA is an airborne concentration of 400ppm (parts per million). Using a large Fragrance Lamp for the recommended 30 min period, in an average sized room, results in an airborne concentration of IPA around 19ppm, assuming zero airflow. Allowing for normal household conditions with a small airflow, the concentration will be even lower than this.


What is the Fragrance made from

Our main range of Lamp Fragrances use a blend of natural, nature identical and plant extracts as components. Our typical fragrance composition is similar in style to most high-end designer perfumes for example, or many of the well-known high-end designer candle brands. None of our fragrances are tested on animals, and we are wholeheartedly against testing products on animals. Our Aromatherapy Lamp Fragrances use only 100% pure essential oils as the fragrance component.
