Intensity7106 cd
Throw169 m
CD/LM factor2.03
CRI95

The E07 SST20 NW flashlight has 3500 lm. It will provide an exceptionally bright and powerful beam of light. The E07 SST20 NW flashlight has 7106 cd. It provides a much brighter and more intense beam. The throw distance is the farthest distance the flashlight can light an object. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is. A flashlight with a higher CRI can show colors more accurately. This is useful for examining objects, it helps tell colors apart in low-light or nighttime. Flashlights with a CRI of 95 or higher are usually seen as top-tier. They may come with premium features and parts.

Anduril lets users customize many parameters. These include mode spacing, mode order, and shortcuts. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The light doesn't have predefined brightness levels or fixed modes. Instead, the ramping mode lets you adjust the light smoothly within a specific range.

You can use Strobe for signaling purposes. It can also be used for self-defense or to attract attention in emergency situations. The E07 SST20 NW's SOS mode produces a specific sequence of long and short flashes. It signals distress or emergency.
