Overview
NEBO built the Einstein in anodized aluminum with five light modes, from a brief turbo burst to a red mode that protects night vision. It runs on the included rechargeable battery or on a pair of disposable cells.
Flexible power is its main angle, since you can swap to disposable cells when the rechargeable runs flat. Turbo steps down after a few seconds to protect the battery, so sustained brightness is the High mode.
Who it's for
Campers, hunters and workers who want a durable, rechargeable light with a disposable battery fallback will appreciate the flexibility. Anyone needing long periods of full output should look at a different design.
Pros and cons
- Five modes including red
- Backup disposable battery option
- Aluminum body with drop resistance
- Long runtime on low
- Turbo limited to short bursts
- Backup batteries not included
- Charging time not listed
Performance notes
Brightness and runtime trade against each other: higher modes reach further but drain the battery faster. Turbo drops back after a short burst to manage heat. Disposable cells run the light at reduced output.
