Princeton Tec Fred

One hundred and thirty hours in low red. That's over five days without changing the batteries: the Fred is built around battery life, not peak power.

Four LEDs

Three white LEDs and one ultra-bright red LED, each with two levels.

• Low red: 1.5 lm, 1 m range, 130 hours
• High red: 12 lm, 5 m range, 12 hours
• Low white: 30 lm, 9 m range, 41 hours
• High white: 200 lm, 21 m range, 5.5 hours

What these numbers mean

The low white mode at 30 lm for 41 hours is the one you really use while camping: enough to cook, set up a tent, and find your belongings for several nights in a row on the same set of batteries.

Controls and adjustment

A single rubberized button on the top, and a tilting arm bracket to choose the beam angle.

The body

Injection-molded, impact-resistant polymer. IPX4 rating: splash-resistant.

Powered by three AAA alkaline batteries.
