2 sourcesall derived$31.99as of Oct 19

The Eclipse Fresno is the proven-blackout specialist, laboratory-tested to block 98-99.9% of sunlight through patented Thermaback construction. Bob Vila praised the Eclipse line for blocking 'nearly all sunlight, even in the middle of the day,' and reviewers note no light bleed from the edges, no chemical smell, and roughly 40% noise reduction. It ships as single panels with a rod-pocket header. As a thick, durable, near-total blackout panel at around $40, it is excellent.

Strengths
  • — Laboratory-tested to block 98-99.9% of sunlight and UV rays, with patented Thermaback/Thermaweave construction
  • — Bob Vila named the Eclipse Microfiber line 'Best Lightweight,' blocking 'nearly all sunlight, even in the middle of the day'
  • — No chemical or plastic smell, with reviewers reporting no light bleed from the edges

Sun Zero Oslo Theater Grade Extreme 100% Blackout Rod Pocket Curtain Panel
Ranked #3 in Best Blackout Curtains
Sun Zero Oslo Theater Grade Extreme 100% Blackout Rod Pocket Curtain Panel
2 sourcesall derived$14.29as of Oct 19

The Sun Zero Oslo Theater Grade Extreme is a polyester rod-pocket blackout panel sold singly, 52 inches wide in 63, 84 or 95-inch lengths. Bob Vila's tester named it the best bang for the buck, rating it 4.5 of 5 for effectiveness and 5 of 5 for value, and liked its heavy, velvety fabric. Reviewed tested three sets bought from different retailers and found they do a decent job blocking light, but its staff thought the shiny polyester looks cheap.

Strengths
  • — Bob Vila rated it 4.5 of 5 for effectiveness and found it performed well once installed
  • — Heavy fabric with a plush, velvety feel, per Bob Vila
  • — Rod-pocket header avoids light leaking through grommet holes, per Bob Vila
Watch-outs
  • — Heavier weight makes the panels harder to slide open and closed, per Bob Vila
  • — Reviewed's staff found the shiny polyester looks cheap
  • — Bob Vila found it a bit confusing to tell which pocketed end is the top

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

Eclipse Fresno

Its near-total light blocking puts it just behind the NICETOWN Contemporary Lined Blackout and Amazon Basics Room Darkening Blackout. Its rod-pocket/back-tab header is less grab-and-go than the grommets on the NICETOWN Contemporary Lined Blackout and Amazon Basics Room Darkening Blackout.

Sun Zero Oslo Theater Grade Extreme 100% Blackout Rod Pocket Curtain Panel

In Reviewed's lab tests the Amazon Basics Room Darkening Blackout blocked more light than every other curtain tested, the Oslo included. Like the Eclipse Fresno it hangs from a rod pocket rather than the grommets on the NICETOWN Contemporary Lined Blackout and Amazon Basics Room Darkening Blackout.
