LEMOMO $$
Triple-weave room-darkening panels; the listing says 85% to 99% light blocking
LEMOMO's triple-weave polyester panels come as two 52 x 84 inch grommet panels. The listing says they block 85% to 99% of light, with darker colors blocking more, so treat them as room darkening rather than full blackout.
Who it's for: Rooms that need to be darker but not pitch black, in a thermal triple-weave fabric.
Skip if: You need full blackout for day sleeping; pick a lined panel.
Alternatives with different tradeoffs — not clones of the same pitch.
