Hello, this is Brad again from your trusted team and I’ll be going over Fenix’s brand new adjustable beam light called the Fenix FD65! This extremely bright, focusing light has 5 different brightness levels plus strobe and SOS and can alternate between spot and flood by twisting the focusing ring around the head of the light and can reach up to 3,800 Lumens running off of four rechargeable 18650 batteries! It features a 90 degree flood light beam angle and the high powered spotlight will reach 1,345 feet/410 meters at 54 degrees. This neutral white light is very useful and highly recommended for outdoor activities such as caving, hiking, camping, outdoor photography since it does come with a ¼” tripod socket and many more. The TIR optical focusing lens was designed to give a smooth and even beam with three Cree XHP35 HI neutral white LED’s have a lifespan of 50,000 hours.


This light weighs in at just over 15 ounces without the batteries and with the batteries will be approximately 19 or 20 ounces and is 6 inches long. The Fenix FD45 has two switches on the body, an “H” switch that you press and hold for 0.5 seconds to turn it on HIGH output and can single click to turn the brightness up. You can also press and hold it for 1.2 seconds to enter Strobe mode. Now, the “L” switch has the same functionality where you press and hold for 0.5 seconds to enter low mode or single click to turn the brightness down and press and hold for 1.2 seconds to enter SOS mode. To turn the light off you can hold any switch for 0.5 seconds. This new light can also be used on TWO 18650’s for emergency situations but you will not be able to use SOS or Strobe with only two batteries installed in the light. The strobe setting will be an intimidating 3,800 lumens and the SOS at 150 lumens.
