This is the copper model of the Emisar D4V2 flashlight. Included are the items shown in photo 1: a lanyard and spare O-rings. Batteries are not included. There is some oxidation on the copper, but there are no noticeable scratches or stains. 【Shipping to Hokkaido and Okinawa is not possible】 Main specifications: ・LEDs: Four in total, two 2700K and two 4500K Nichia E21A LEDs ・Uses one unprotected flat-top 18650 lithium-ion rechargeable battery - Operation has been confirmed with Keeppower NH1831 and Efest INR18650 - Batteries can be added for an additional fee, so please comment if you would like them ・Maximum output is approximately 1200-1500 lumens based on simple measurements ・Employs the Anduril 2 UI A key feature of this model is the ability to switch between the two channels of 2700K and 4500K. For example: ・Use only 2700K ・Use only 4500K ・Instantly switch between 2700K and 4500K ・Use 2700K and 4500K simultaneously - Use both at the same output - Gradually change from 2700K to 4500K by mixing both channels (Like gradually changing from warm to white with ceiling lights) Various functions, including this channel operation, are implemented in Anduril 2. While it can do a lot, it's also true that it can be a bit complicated. If you press the switch the wrong number of times, it will perform an unintended action. Those familiar with Anduril 2 will have no problem, but first-time users may be confused. A manual is not included, so I will enclose a paper with instructions on how to use Anduril 2 for reference. I hope that those who can manage with that paper and information from the internet will purchase this item.
