Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources like streetlights and security lamps. In new research published in the journal Biological Conservation, scientists say a simple change in artificial lighting could help reduce this particular threat.

    There used to exist low pressure sodium vapor lamps that emit only the Natrium d-line, which is a ultra warm white monochromatic “color” around 1800K. It is also very economical, can produce 15000 lumen from just a 90W bulb. Before LED that was the most economical electrical light bulb. The only reason they prohibited them was the quicksilver inside the bulbs. What a mistake! Best bulbs ever for outdoor street lights. I hope they can have a comeback.
