No1199 Full spectrum light is inevitable for every creature, including human being. From a book light; medicine of future, by Jacob Liberman. Ms Lemon, lovely parakeet of my family, often feels itchy. Her head skin is reddish lately. I bought full spectrum, including ultra violet, light bulb. It was for plants to raise them in rooms. Plants need ultra violet light. Human being needs it, of course. A young Japanese woman got her sight weaker two or three years after migrated from Adelaide, Australia, to London. She wears sunglass. It was natural in Adelaide. Now, research starts with Lemon. Five minutes after I switched on the plant light, she began to sing. After a while she came on my shoulder to show her thanks to me, I assume. Kyokkou denki kougyou KK: kyokko@asahi-lamp.jp
