This is the new Lumens Factory flashlight, Seraph SP-6M, which can use Surefire P60 compatible modules. This listing is for the body and spare O-rings only; the lamp module, batteries, etc., are not included. This model has several bezel ring variations; this one has a stainless steel crenellated (?). Like the SP-6, it can use lithium-ion rechargeable batteries such as 18650 and 2xCR123A, but this SP-6M can also use 18350 batteries by removing the part with the second logo from the right in photo 4 and assembling it as shown in photo 5, making it shorter. I have tested it 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) Those who purchase this product likely already know, but there is compatibility between the body, lamp module, and batteries. For example, not all batteries labeled as 18650 will work. Even P60-compatible lamp modules may not fit this body. Please understand that we cannot accept returns or refunds due to incompatibility with your batteries or lamp modules. We can also offer a set of the batteries and lamp modules that we have tested. We have inexpensive lamp modules and also more expensive genuine Lumens Factory lamp modules, so please feel free to inquire.
