LED Lights A Health Hazard: New Research from Israel – …

H.J. Round was working in the UK’s Marconi labs when he noticed electroluminescence of a ’s-whisker silicon carbide diode in 1907. LEDs which followed in 1927 were so dim as to be impractical until Biard and Pittman of Texas Instruments made the first practical red LED in 1961.
