This is the new Lumens Factory flashlight, the Seraph SP-6M, which can use Surefire P60 compatible modules. It comes with the body and spare O-rings only; lamp modules are not included. Like the SP-6, it can use lithium-ion rechargeable batteries like 18650 and 2xCR123A. However, this SP-6M can be shortened to use 18350 batteries as shown in photo 5 by removing the part with the logo in the middle of photo 2. I tested the light with a Lumens Factory D26-LED module using the following batteries: [18650 Configuration] ・Keeppower 18650 P1835J (protected button top) ・Keeppower IMR 18650 NH1832 (button top) ・Keeppower IMR 18650 NH1831 (flat top) [18350 Configuration] ・Keeppower IMR 18350 UH1835P (flat top) As I am the first purchaser of this model, it's a brand new product. If you are interested, please consider it.
