Amazon offers Prime members the Brunton Flip Task Light in Blue for $7.83. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $5.58.) That's tied with our February mention and the lowest price we could find by $8. It features an output of eight lumens, diffused lens, twistable head, built-in clip, and up to 10 hours of runtime.

Note: It's scheduled to be in stock on May 19, although it can still be ordered at this price now.
