FAQ on light and Needlite

  • Can I get too much light?
  • Will I get dazzled by Needlite?
  • How do I best position my Needlite?
  • Do I get UV radiation from using Needlite?
  • Do I get vitamin D with Needlite?
  • Where do I find the technical specifications for Needlite?

No, there is no evidence that you can get too much light. However, it is important to emphasize that you need to place Needlite so that the light is comfortable for you to be in. It's important that you do not have too much contrast in and around your field of vision. That will cause fatigue both with you and your eyes. Also remember to turn off the light a few hours before going to sleep. The daylight increases your energy due to increased production of the serotonin hormone that acts as a stimulant to our organism. If we do not turn off the light 2-4 hours before bedtime, we may find it difficult to fall asleep, as well as sleep quality may be adversely affected. But with plenty of daylight during the day, you actually sleep better at night too.

Needlite is carefully designed so the light does not dazzle or irritate. Receiving the light from the front offers great advantages, both in relation to the body's energy level and mood, but also in terms of getting even and comfortable daylight on the work surface.

In order for the brain and the body to benefit the most from daylight, it must reach the right receptors in the eyes. We are biologically adapted to a life outdoors and the sun's light. Therefore, the daylight should also ideally reach the eyes in an angle from above. The height of Needlite helps optimize light absorption through the eyes.

In addition to the design of Needlite, the positioning of the lamps on the table is also important. Needlite always comes as a set of two lamps. The lamps are placed on either side of the screen. The exact location is depends on you: Some want the lights a bit out of sight, while others prefer a location closer to the screen.

The same goes for brightness: Some prefer the lower brightness, which works well as daylight supplements, while others prefer higher brightness levels. The effect on the energy level depends on how much light that reaches the eye: the higher the brightness and/or the closer the light is to the eye, the greater the effect.

It's easy to enjoy the effects from the daylight in Needlite: Plug in the wires, place the lamps on your desk on each side of your screen and turn on the lights by a soft touch on the base of either lamp.

We are all different with different preferences and th most important advice is to find a brightness and a position of the lamps that work for you. But here are a few tips to get you started:

* We recommend that you start by placing the lights slightly away from the screen. This works great for some. Others prefer the lights closer to the screen - actually quite close to the screen. In this way, the area of brightness of the screen is expanded, and the often strong contrast between the light of the screen and the darkness of the surroundings is now moved further to the side. This puts less strain on the eye due to fewer adjustments between light and dark during the day.

* We also recommend that you start with your Needlite set at a lower brightness. Getting daylight all day ensures a very good effect even at lower brightness levels. If you prefer more light - or are in need of an energy boost - it's easy to increase the brightness with a soft touch or through the Needlite app.

No. Needlite emits light within the visible spectrum only and contains no UV rays.

No. Vitamin D is primarily absorbed through the skin when exposed to the sun's UV-B rays, and also through certain foods. Therefore, you will not get a vitamin D supplement by using Needlite - or other daylight lamps - since they do not emit UV radiation. If you want to know more about vitamin D, there is an excellent fact box at the Food Institute at DTU - click on this link (in Danish) and scroll down to the end of the article.
