The light itself uses Cree XPG LEDs a highly efficient option from a world leader in LED development. At their brightest these LEDs pump out an impressive 230 lumens and this can be stepped down with two lesser settings to reduce the amount of light you spill when close to your swim. For a much stealthier option a little red screen can be pulled over the front of the torch to produce a red light that is less disturbing for fish. The use of this little screen means you’re getting as much power as possible from the white LEDs instead of switching to separate red LEDs which tend to have much less output capability.
