Best D battery powered lanterns

Top pick: Dorcy 2000 Lumen 4D Multi-function Lantern — it runs on four D cells, so it keeps going through a multi-day outage on batteries you can stock up on, and 2,000 lumens lights a whole room. The multi-mode switch lets you dim it to stretch runtime overnight.

Who the others suit:

• Dorcy Adventure Max 41-3120 — the brightest of the D-cell group at 3,000 lumens with a 100-hour high-mode claim; best if you want maximum light for a big space.
• Dorcy Adventure Max 41-3119 — same family with emergency signaling; good for a hallway or stairwell where a beacon matters more than floodlight.
• Coleman 4D LED — the simple, proven choice if you just want a familiar lantern that takes D cells.
• Energizer WeatheReady PRO-360 — 500 lumens for 150 hours on high and water-resistant; the pick for long, low-draw overnight light.

One caveat: several of the cheaper LED lanterns here are rechargeable or AA, not D-cell, so check the battery type before you buy.
