Our verdict

A 12 inch level that swaps the usual bubble squint for a light that turns green at level or plumb, useful anywhere lighting is poor or the angle is awkward.

Overview

A 12 inch digital torpedo level from Franklin Sensors that lights up green when a surface is level or plumb, built for anyone who needs a clear reading in low light or from an angle rather than squinting at a small bubble.

Instead of reading a bubble, this level lights up and changes color as you approach level or plumb, then turns solid green at true zero, which is easier to catch from a distance or an odd angle. It still carries two built-in bubble vials as a backup. It runs on one AA battery, so the light feature depends on that battery rather than being purely mechanical like a standard torpedo level.

  • 12 inch magnetic torpedo level
  • Digital light turns green at level/plumb
  • Visible in dark and normal light
  • 2 backup bubble vials, 1 AA battery

Who it's for

Anyone leveling in a dark crawl space, under a cabinet, or from below a shelf, plus RV and camper owners who level at night at a campsite. Also suits users who find a small bubble hard to read and prefer a light-based signal.

Pros and cons

Pros
  • Lights up and turns green at level or plumb
  • Readable from angles and distances a bubble is not
  • Works in dark and dimly lit spaces
  • Backup bubble vials included
Cons
  • Needs one AA battery to use the light feature
  • No battery-life rating given in the listing

Performance notes

The light display is built to read from a distance and from odd angles, since the color change is visible well before you are looking straight at the vial. Franklin Sensors states the lights work in dark, dimly lit and normal conditions alike, and RV leveling at night and crawl-space work are named uses. The two built-in bubble vials remain as a mechanical check if the battery runs out.
