Reasons you should use Sun Lamps for Windowless Office

When your office doesn’t have any windows, what type of lighting you add becomes even more important. Especially since you will most likely be using the lights during the long working days. 

And not any lamps on the market are suitable for office work. 

A good lamp is essential for your office because it offers so many benefits. An enclosed workspace often results in a feeling of claustrophobia and lack of vitality but a suitable light source can help to overcome this problem.

Compared with a dimly lit working environment, it helps you to focus more, reduce stress, and keep the morale steady. You can also reduce the negative effects on your eyes and your brain due to more excretion of the eyes and more stress on the brain when working in low light.

Similarly, a light source that is too bright will also cause your eyes to be dazzled, fatigued, and easily cause stress. 

Another interesting thing is that workplace lighting has a great influence on your working morale, thereby greatly affecting your productivity and work efficiency.

Good office lighting can also increase energy levels and help keep your spirits up on long days working.

Consideration when choosing lamps

There are a lot of things to consider when deciding on affordable lamps for your office, especially for windowless ones. Lamps for each office are very different, depending on your demands and the room’s technical requirements. 

When selecting ceiling office lighting, you should consider the size of the room. The 1000 Bulbs Lighting Blog suggests you need 50 lumens per square foot for desk and task lighting. Or 20 lumens per square foot for floor lighting.

However, the ceiling lights are not the most important lights. What you should focus on most are the lights you get on the spot where you do most of the work (usually, the desk).

A lamp with sufficient and comfortable light is the best choice because when there’s not enough light, and a dim room can cause eyestrain, but too much light can cause glare and make it difficult to see your monitor.

Besides, you should consider your work’s nature to choose suitable lamps: your works are mostly on the computer, or mostly on paper files?  How many areas of the room do you work in? Each workspace should have adequate light for the task performed there.

The number of working hours a day you spend in the office should also factor into your lighting selection. If you spend long hours in a windowless office days after days, you should choose a light source that is similar to daylight.

Once you have assessed the room, you can better decide what your lighting needs are.

Frequently asked questions

You can try some useful tips to make your office feel bigger and more comfortable such as: 

  • Choose a light paint color to make your office brighter and also better light up. The walls with bright white seem to be the most suitable color for a windowless office.
  • Adjust your lighting by using appropriate lamps, avoid turning on the overhead lights, and create warmer light with lamps instead.
  • use mirrors to visually expand the room and add a sense of depth. Mirrors also reflect the lights and make your office feel bright and warm.
  • Bring in some natural elements. Plants help your office be more lively and create a comfortable atmosphere.

The answer is YES. Working in a dark office is very harmless for your eyes, your mood, and then your work efficiency.  The dimly lit working environment makes you lose focus, more tired, and less productive. Moreover, the dimly lit space that you work in can also affect your mental capacity in the long run.

There are a handful of ways to create the illusion of more natural light in your home, from a system of lighting, mirrors to houseplants, etc. 

Artificial lighting is essential in any room, especially ones that lack a lot of natural light. Add full-spectrum light bulbs (they’re designed to simulate daylight) to the light fixtures in rooms with poor lighting to quickly brighten up your home with some soft but warm artificial light. 

To take advantage of artificial lights in faking natural light efficiently, you can combine them with bright paint colors and one or some mirrors to help the light spread evenly throughout the room and create a sense of depth. 

One more great way is adding some houseplants. Bring a few low-light-tolerant plants, like ferns or spider plants, into a room with little-to-no-natural light to usher in some ethereal vibes and keep the air clean.

You can also try to gloss up your surfaces. A little gloss goes a long way when faking natural light at home. Besides, investing in decor items with glossy or metallic finishes seems to be a great idea to give the impression you have more light in your home than you really do.

If the office’s layout makes you feel depressed, don’t hesitate to do some below cost-effective touch-ups. 

  • Add a touch of life to your desk with a plant. Not only does this add color and brightness to your work area, but it also screams health, wellness, and life.
  • Add Dimension: Crates, bins, baskets, and pegboards not only add storage to your workspace but also give your desk an eye-catching dimension. Try clear acrylic storage containers for a sleek, modern look
  • Tack Up Inspirational Quotes: you can print or draw them on your own. Get creative with how you hang or frame your quote to add even more style to your space. 
  • Upgrade Your Office Supplies: the perfect way to add a pop of color, class, or comedy to your workspace, etc.

A little change can also bring new life to your office and make your spirit up. Let’s try now!
