Distinguishing Between RG0 Standard and Flicker-Free Technology

When choosing a study lamp or desk lamp, many people can easily get overwhelmed by a myriad of specifications like CRI, lumens, color temperature, etc. However, few truly understand the LED technology and standards applied – one of the most crucial factors determining eye health safety during long-term use.

And when this factor is considered, many confuse RG0 LED chips with Flicker-Free technology – terms very familiar on lamp product packaging. The most frequently asked questions are: Is RG0 the same as Flicker-Free? Does RG0 include Flicker-Free? Let's explore the RG0 standard and Flicker-Free technology, currently integrated into HyperWork's Nova and Luna LED desk lamps.

Why are RG0 LED chips and Flicker-Free technology often misunderstood?

• Both aim to protect eyes, so they are often considered the same.

• Many high-end products integrate both but do not explicitly state each component separately on the packaging or in the description.

• Common phrases like “stable, harmless light” are often generic, making it difficult for readers to differentiate.

What is RG0?

RG0 (Risk Group 0) is a photobiological safety standard, according to international regulation IEC 62471. A product that meets RG0 means it poses no risk to the eyes during long-term use at close range, which is very important for study lamps and desk lamps.

Unlike parameters such as CRI (color rendering index) and lumens (brightness), RG0 is a safety index, only granted when a lamp passes numerous strict tests for blue light, thermal radiation, and potential eye damage. Specifically:

• While regular lamps may still emit blue light at levels harmful to the retina when used closely or for extended periods, RG0 LEDs have been certified as absolutely safe for eyes, even for young children or those who use them frequently at night.
• Recognized by international standards organizations.
• It is currently the highest safety level for consumer lighting devices.

RG0 LED is not an optional feature; it is a premium standard that not every lamp on the market achieves, especially in the sub-1 million VND price segment.

What is Flicker-Free?

Flicker-Free technology provides more stable light, completely eliminating the flickering often found in cheap LED lamps, which can cause headaches and dizziness with prolonged use, especially when working in front of a screen.

The cause of flickering is that LED lamps use alternating current (AC), causing the light to fluctuate with the electrical frequency (50-60Hz). If not processed, the LED will flicker continuously, even if it's hard for the naked eye to see.
Flicker-Free overcomes this by integrating a high-quality AC to DC converter and a stable control circuit. As a result, the light is continuously maintained without flickering, protecting the eyes during long-term use.

Is RG0 the same as Flicker-Free?

Many users often confuse Flicker-Free technology with RG0 LED chips, as both aim to protect vision and frequently appear in high-end LED lamp models. However, these are two entirely different technologies, with distinct operating mechanisms and uses. A lamp with RG0 is not necessarily Flicker-Free, and vice versa. Clearly distinguishing between them will help you choose products more intelligently and effectively.

HyperWork's Nova and Luna LED desk lamps meet the RG0 standard and incorporate Flicker-Free technology while maintaining an affordable to mid-range price for users, providing safe and reliable lighting quality.

Related Questions

- Who should use LED lamps with RG0 LED chips and Flicker-Free technology?

Any user of LED lamps should be concerned with the RG0 standard and Flicker-Free technology. Especially children, students, and university students who use study lamps frequently for long periods should prioritize devices with good light quality that are absolutely safe for their eyes. Everyone can protect their eye health with LED lamps using RG0 LED chips and Flicker-Free technology, but for those who are exposed to artificial light frequently or have sensitive vision, this is almost mandatory.

- Can an RG0 LED chip, Flicker-Free bulb be used as a night light?

Absolutely. RG0 LED and Flicker-Free are safe and friendly, perfectly suitable for use as a night light, especially when choosing the right color temperature and brightness. For example, warm yellow light (2700–3000K) instead of cool white, prioritizing adjustable brightness to facilitate sleep, and not causing glare upon waking. Although RG0 and Flicker-Free are very safe, it is still advisable to avoid directing the light straight into the eyes when placed near the bed.
