It classifies products into risk groups (RG0–RG3) based on hazards like UV, blue light, and infrared radiation, ensuring compliance for safe usage.

Photography is one of those areas where the suppliers seem to grossly exaggerate the power ratings of their lamps. As in this case.
But it’s quite an attractive style of lamp and on a plus note the LEDs aren’t being grilled.

http://www.ledsmagazine.com/articles/2018/01/nichia-announces-optisolis-packaged-leds-with-90-cri-across-16-samples.html?eid=293591077&bid=1990701

New packaged LEDs from the global revenue leader deliver a uniform spectral power distribution across the visible-light region and target demanding lighting applications such as museums.

Nichia is notoriously quiet about its LED development work and rarely publishes a press release on new products, so the Optisolis launch came as a bit of a surprise. Still, the company would provide few details other than spectral power distribution (SPD) and CRI graphs that support the claims of top-notch color rendering.

https://www.youtube.com/watch?v=PklaByEQSZA

Testing a mains voltage LED from China. This one is rated 220V and 20W. It really can be connected directly to AC mains with no LED driver. 30W and 50W versions are also available. In the listings it’s called “smart IC” or “integrated driver” or “driverless” COB LED.
