We’ve been shippng these for a couple years now, and the 532nm green diode is noticeably brighter than red in daylight — it’s what most buyers go with for outdoor work up to 50 meters or so.
Accuracy is ±1mm at 5 meters for level, which is tighter than teh typical ±1.5mm you see on cheaper units, and orthogonal tolerance of ±1mm at 3 meters means your corners won’t drift.

The 4 vertical and 1 horizontal lines come on at the same time, so you can set up a full grid without flipping the unit, and the self-leveling range is ±3° — it won’t recover if you’re on a steep slope, but for most floor-to-ceiling layouts it’s fine.

Battery life is a solid 24 hours on the lithium pack (usually 20-22 in cold weather below 0°C), and the 5/8-inch thread fits standerd tripods, though the included bracket is a bit flimsy if you’re mounting it on a pipe clamp.

We keep COAs on file for the laser diodes, but we don’t test every unit for beam width — the spec says 2mm at 5 meters, and in practice it’s usually a hair wider, especially after the lens warms up.
It’s not suited for outdoor alignment in direct sun past 30 meters; the green beam washes out, so you’ll need a detector or a red unit for that.
Our MOQ for this laser level is typically 50 units per order, but we can discuss smaller trial quantities if you're a new partner.
Lead time is usually 15-20 working days after order confirmation and deposit, depending on current production load.
Yes, we can issue a factory calibration certificate with each shipment, and third-party certification is available upon request at an additional cost.
The lithium battery is built-in and not user-replaceable, but it supports USB charging and lasts 24 hours on a full charge.
Each unit comes in a foam-lined carton (21x15.5x24.5 cm) with a gross weight of 1.8 kg, suitable for air freight without special handling.
