Ionizing lighting at Bronovo Hospital


The Bronovo Hospital (Netherlands, The Haege) uses ionizing lighting cleaning the air in the dermatology department.

A fresh look at light for the Bronovo Hospital

Cor Wegman the Head of Technical Services at Bronovo shares  “At our technical service department the request came to do Bronovo Ionisatie verlichtingsomething about the odor in the dermatology department. In this section there is a device which treats skin disorders by means of UV light. An additional effect is the unpleasant smell after the treatment in the the area where this unit is. The first solution we tried was adjusting the ventilation of the room.

We thought that increasing the ventilation capacity would make the smell disappear. Unfortunately the smell was to persistent and it did change into satisfactory outcome. During this time I came in contact with Freshlight. They were looking for a test option in the health sector for their air purifying lamps. After consulting with Freshlight our dermatology department become this test case.”

Innovative alternative

“The products of this company are unique. Clean air, daylight and energy saving in one lamp! The applicability was very simple. In the treatment area, we did not need to implement major changes to equipment and / or construction. The only thing we had to do was changing the old ballasts from fluorescent fixtures by a high frequency VCA. This ensured that the lighting was another 40% more energy efficient. The energy savings gave us a full payback within one year.

The lighting is put into use. Very soon we got used to the bright refreshing daylight. But where we are most satisfied by the disappearance of the smell almost entirely in the treatment room.”

The Future

“At this point we are considering future projects, like our nursing home for incontinent residents and the department where the linen is collected. The stench of urine and other VOCs will be reduced by ionization. Freshlight products are promising and help us achieving our goal to optimise well-being of our guests and staff minimal costs”. So says Cor Wegman.

The Posten – The Miracle of a Lamp

Press release from published 17/09/2009. This is the local Enschede Newspaper. Unfortunatley it’s in Dutch, but you get the idea.

Nursing-home-outsideInhabitants of ‘Carecentre’ The Posten are benefiting enormously because of
so-called ‘refreshinglamps’. At first the direction thought this was another practical joke that would
only cost money…

ENSCHEDE, The Netherlands –

The direction of carecentre The Posten is considering to buy more daylight-
and aircleaning lamps. These lamps have the ability to cause the inhabitants to
become more alert and active. The ionising element purifies the air in the vicinity.
In smoking areas those present aren’t bothered anymore by the smoke!

Just last year, director Willem Marcelis from The Posten initially really thought this
was an ‘April’s fools’-joke, when a daughter from one of the inhabitants asked him why
he wasn’t using the full-spectrum and ‘airfreshening’ lightbulbs yet.

Mr. Marcelis: “It was almost too good to be true. I was thinking to myself:
‘Yet another one who tries to make money off of us…’
But as it turned out, his curiosity was most definitely aroused. First up he started to
investigate on the Internet and after that he ordered a couple.
Those lamps were tested in the so-called ‘living rooms’ in the closed section.

cafeAccording to teamleader Erwin Wessendorp, the results were ‘astounding’.
“At first I also didn’t really believe in the lamp, but the results surprised me enormously.
If you take a look at the observationlists and you compare the ‘before’ and ‘after’,
you see major differences. Also, the bright light activates the brain more. Because of this,
people have more focus. The effect of the ioniser is even bigger. It ‘cleans’ spaces for around 95 % from smoke and odours.

Mr. Wessendorp: “People in the smoking areas, who were at first complaining about
prickly eyes, aren’t bothered anymore now! The ioniser also operates perfectly in spaces
with people who are incontinent. You don’t smell the urine anymore..!”
