Which is better for laying out a whole room?

The 360-degree green kit. Its three 360-degree lines mark floor, wall and ceiling lines from one setup, while the DW083K only projects spot points.

Is the green laser worth the extra $125?

If you work in bright light or need lines, yes. The green beam is more visible and the kit adds 360-degree lines, IP65 sealing and a rechargeable battery. For occasional spot checks, the DW083K is enough.

Which one is better for steel track and curtain wall work?

The DW083K. It is built as a self-leveling spot laser for bottom and top track installation, and its magnetic pivoting bracket mounts on metal surfaces.

Do both use the same batteries?

No. The green kit uses DEWALT 12V MAX CXT lithium-ion batteries and includes a charger. The DW083K runs on 4 AA batteries, rated about 40 hours.

Which is more accurate?

Both are rated +/- 1/8 in. at 30 ft. The DW083K is listed at 1/4 in. at 100 ft, so expect more spread over long distances.

Which lasts longer on a charge?

The DW083K is rated about 40 hours on AA batteries. The green kit's runtime depends on the 12V battery used, and green beams typically draw more power.
