7 Key Things Everyone Should Know About Eye-Caring Desk Lamp
You may have read the information on what kind of LED table lamp you should buy from place to place. However, few of the blogs or articles conclude with key factors that distinguish a true eye-caring desk lamp.
Here are the 7 key things you want to consider before making a purchase.
1. Low Blue Light
The hazard of blue light is widely acknowledged. Repeated exposures to blue light may suppress melatonin, and even worse, increase the likelihood of developing cancers and circadian rhythm disorders.
From high to low, the Photobiological Safety Standard IEC 62471 defined 4 risk groups: Risk Group 0 (RG0, no risk), Risk Group 1 (RG1, low risk), Risk Group 2 (RG2, moderate risk), Risk Group 3 (RG3, high risk).
Therefore, the highest standard for no blue light is RG0 level.
2. Wide and Evenly-Distributed Illuminance
Firstly, illuminance serves as the best indicator to judge the quality of a table lamp’s lighting. Reading spaces where the use of computers is prolonged should have 500 Lx as a minimum light level, making sure your LED desk lamp has enough oomph to properly illuminate your work area, so your eye won't be straining and dry from being in constant weak brightness.
Besides, the focusing of the light beam is also worthy of attention. The ability to direct light only to the necessary part of your workspace allows you to focus on what is important and helps reduce glare.
3. No Glare
If you have been temporarily blinded by the oncoming car's strong beam at night or unconsciously or subconsciously raised your hand to block the sunlight when walking out of a building at noon, then you must know what glare feels like.
A good optical design for LED desk light starts from effectively mitigating the harsh, concentrated beam to obtain a soft and pleasant light distribution. Generally, a LED desk lamp with a diffusion panel and uniformly distributed lamp beads would provide effective glare reduction to protect your eyes.
Flicker is caused by the temporal variation or ripple in the power supply to the LEDs. It feels like you can see the ripples in the lights.Long-term exposure to invisible or imperceptible flickers may cause malaise, headaches, and impaired visual performance.So look for a lamp with flicker-free LED bulbs.
5. Excellent CRI
High CRI LEDs showcase the colors as they would be in natural sunlight. Low CRI lighting leads to a loss of color fidelity and may cause eye fatigue. Generally, standard CRI should be higher than 80, and 90 would make it to the excellent level.
For reading, writing, and other visually strenuous works, it's highly recommended that the CRI should be greater than 90.
6. Lamp Head/Arm Adjustability
If you want to move the light in different directions and positions as you need when working or reading, then a lamp equipped with a flexible arm and movable head is your best option.
What's more, an adjustable design is crucial to minimize glare as it allows changes in light direction.
A true eye-caring desk lamp allows you to adjust its brightness level and color temperatures to make your eyes comfortable.Besides, adaptable color temperatures make mood settings diverse: Warm amber light for relaxed reading and cold white for being awake and right there for the task at hand.
