Desk lamps provide “task lighting” for reading, writing, studying, DIY, computer work, etc.
For this reason, a good desk lamp should offer the following features:
A bright, clear light that is easy to work under.
A relatively focused beam with minimal glare.
An adjustable design that can be positioned to suit a range of tasks.
Five tips for finding the perfect desk lamp
1. Opt for high-quality light
In general, incandescent bulbs provide a bright, clear light. LED desk lamps are a versatile and energy-efficient option. Pay attention to these two characteristics: CRI and colour temperature.
The colour rendering index (CRI) measures colour fidelity under a given light source. This index is particularly important for desk lamps, where the ability to see contrasts while reading and working is essential. Look for LEDs with a high CRI, between 85 and 100.
Colour temperature is a standard measure of the appearance of light, often referred to as the ‘warm’ or ‘cool’ appearance of a light. LED desk lamps with a colour temperature between 2700K and 4500K generally provide a bright, pleasant light in which to work.
2. Look for adjustability
Another tip to help you buy a desk lamp is adjustability. Adjustable desk lamps allow you to fine-tune the location of the beam for specific tasks and to minimise glare. There are several possible articulation points, including swivel heads, swing arms, boom arms and goosenecks.
3. Choose the right size desk lamp
For small offices, choose clip-on lamps or lamps with a small base to preserve valuable desk space.
For larger offices, consider a lamp with a longer reach (such as an architect or swing arm lamp) or use additional light sources around the room to ensure full coverage of your office.
As a general rule, your light source should be positioned higher than your head, but out of your line of vision; it should never be in direct line of sight. If it’s too low, it may not cover your work area sufficiently; if it’s too high, the light may be too diffused.
4. Learn how best to position your desk lamp
The lamp should be positioned so that shadows don’t cross your desk as you work. If you’re right-handed, this means placing the light source on the left side of your desk and vice versa.
For adjustable lamps, make sure the arm is long and flexible enough to light where you need it, and out of the way when you don’t.
When used with a computer, desk lamps should illuminate the desk and keyboard without dazzling the screen.
5. Consider the position of the on/off switch
Turning your desk lamp on and off should be easy. Good switch options include pull chains, plinth switches and touch-controlled lamps.
Light tips for the ageing eye
Proper lighting for reading is increasingly important as we age and our vision declines. In fact, studies have shown that people in their 60s need 80% more light to read than people in their 20s. Other symptoms can include reduced colour discrimination and sensitivity to glare. USB desk lamps are another thing to consider. These models have a built-in USB port that allows you to charge smartphones and other electronic devices quickly and easily. Many also have built-in power sockets that offer even more functionality.
