Choosing a table lamp is like finding a reliable bodyguard for your eyes; it needs to be reliable inside and out. The core points to consider are:

1. Safety and Certification:

CCC Certification: This is a mandatory national safety certification, the "identity card" of the table lamp. Ensure the product has this mark.

2. Examine Core Performance Parameters:

1) Illuminance and Uniformity: Illuminance determines brightness, and illuminance uniformity determines whether the light distribution is even. Prioritize AA-grade table lamps, as they provide more ample and uniform light, effectively reducing eye strain.

2) Color Temperature: It is recommended to choose a table lamp with adjustable color temperature (e.g., 3300K-4000K). This adapts to different times and activities, reducing eye fatigue.

3) Color Rendering Index (RA): The higher the value, the more realistic the colors of objects. Choosing a table lamp with an RA ≥ 80 is especially important for children who need to engage in fine motor activities such as drawing and crafts.

4) Flicker: Always choose a flicker-free table lamp. You can easily test this with your phone's camera; if noticeable ripples appear on the screen, it indicates flicker.

5) Blue Light Hazard: Choose a table lamp with an RG0 (no hazard) blue light hazard rating to avoid the risk of harmful blue light at the source.

3. Identifying Brands and Reputation

1) Beware of Marketing Traps: Don't easily believe exaggerated claims like "repairing the retina." Choose brands with a good reputation and a focus on research and development.

2) Check Professional Reviews: Refer to test reports from authoritative institutions or professional media to understand the actual optical performance of the product.

4. Practical Purchase and Usage Suggestions

1) Purchase Channels: It is recommended to purchase from reputable stores or e-commerce platforms and request a formal invoice and warranty certificate.

2) Table Lamp Placement: For right-handed users, the table lamp is best placed on the front left of the desk to avoid casting shadows on the books with your hands or body.
