Personal impressions on L90:

  • Very nice sharp hotspot, no donut hole
  • lower modes has purple tint
  • glass almost falling off, easy to detach accidentally (like I did)
  • surprising lower performance after detaching glass and almost identical parameters with glassed version

*all measurements taken 30 seconds after turning on with 4.20V Moli P45B
