I want to know the answer to the following question:
What LEDs are considered safer than any other?
All the background I'm provided with is that "However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), lead (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous."". Is that enough to answer the question?
Answer: yes
