This data helps tell a story when Lansing becomes an IDSC. We make impact maps which show the amount of unnecessary and harmful blue wavelengths put out by each fixture. #science #lighting21 Sep 2026 03:56 +0000at://did:plc:4hm26dmltr7qtotb5l4b2ibn/app.bsky.feed.post/3mvysxo67gc2rhttps://bsky.app/profile/ashedarksky.org/post/3mvydxssc2k2a4k low-light timelapse on David's moonflower tonight to see if anything interesting shows up.
