From the lab: PTec - FRED Headlamp
FRED puts out 45 lumens in a flood beam via three Ultrabright LEDs. The fourth LED, a red Ultrabright, helps you keep a low profile and preserve your night adjusted vision. The FRED headlamp is stable with its asymmetrical single arm bracket; the large power button is easy to find even while wearing gloves. FRED runs for up to 145 hours in white mode and 180 hours in red mode on three AAA batteries.
