Surefire E1B Backup
The E1B is a flashlight designed to be used as a backup light for law enforcement and related jobs. The light features a Cree LED with TIR optics and two levels of output using a single C123 battery.
The switch of the E1B is new for Surefire lights, it is a clickie switch that goes to high mode with the first click and to low mode with a second one. A light press of the switch without clicking from off gives you momentary maximum mode. This is probably intended to provide maximum light quickly in case of need but it is certainly a problem if you just need low light and want to preserve night vision.
The light runs for about 1.3 hours in maximum mode providing about 80 lumen of light in low mode it will last for about 35 hours at 5 lumen which is good enough for reading and general navigation.
The pocket clip is bidirectional meaning that you can clip the light bezel up or bezel down depending on your preferences the body in anodized aluminum type III is very strong but has been streamlined so it won't be agressive with pockets or clothing this is a good detail if the idea is to keep the light clipped for very long times and use it in case of need. The clip is also very strong and unless something terrible happens the light won't be lost.
This is not the brightest Cree light in the market and it is not the most functional light either but as a general purpose light or a backup light it is a very good option and its certainly brighter in high mode than many single cell lighs out there.
You can get it for $110 from BatteryJunction.
