The report also states that flies living with blue LEDs with yellow filters lived more-or-less as long as the flies grown in darkness.

That's rather comforting to me as most if not all LED fixtures have these.

White LED light is produced by a narrowband blue LED chip (450-460nm) coated with a wideband yellow phosphor (green-red). It's additive, the spectrum is built up. Some of the blue light is converted by the phospor. You are most certainly exposed to the blue light. Those flies were exposed to too much and for too long. This study starts with the premise that blue light is harmful and fails to demonstrate anything.

Most LED fixtures emit a lot of blue, even if the bulb appears a different color. As far as I know, "bug bulbs" are the only ones that actually filter out all the blue- which attracts bugs.
