Light comes in a flip top cardboard box with everything held in place with foam placeholders.

The SP-6 is one of many lights made by Lumens Factory under the Seraph line of lights. Lumens Factory is well-known for making drop-in modules, and now also have complete flashlights in their product lineup, and in tradition to their drop-ins, the Seraph line is modular and customizable with various optional parts. Up the front the SP-6 has a removable stainless steel bezel. Both crenellated and smooth bezels are included, easily unscrewed for easy swapping depending on your preference. Behind the bezel sits a glass lens. The reflector used is made of textured aluminum which is well polished and finished with no noticeable flaws. The LED sitting at the bottom of the reflector cup sits well centered as well. The reflector, LED and electronics make up the drop-in module which can be swapped out with other types of modules. The exterior of the head has an aesthetically clean design with subtle scalloped cuts running around its circumference.

The body of the SP-6 has a definitive structured design, but unlike most other lights which have unnecessary aesthetic touches, the SP-6's design is very bit as much functional as well. Towards the front ht has a series of cooling fins which would serve especially useful when optional incandescent drop-in modules are used. Towards the rear end of the the tube is a pair of rubber rings which provides comfort when holding the SP-6 in a cigar-style grip. Threads on either ends of the battery tube are well machined and smoothly cut with no squeaking or grinding encountered during tests. The internal dimensions of the battery tube is wide enough to accommodate protected 18650 cells. As listed in the contents above, the retail package includes two switches. The one with the orange switch cap is a forward push button switch allows for momentary activation. The other, which has a black rubber switch cap is a purely momentary switch and required twisting for constant-on activation. Functionally, there's no benefit of the momentary switch, however its real intended usage is with high-current modules. Supporting up to 2A of current, the momentary switch with easily handle those without toasting its electrical contact mechanism. Both switches have an average amount of travel and tension, with the forward push button providing a positive tactile feedback when fully engaged. Also, both tail caps are able to tail stand without problems. Type of anodizing was not specified, and has a dark silver color. There were some minor scuffs on the momentary tail cap, but the rest of the body is perfectly coated. The parts of the Seraph SP-6 are compatible with SureFire E and C series lights and accessories as well.

The SP-6 reviewed here came with the 3-mode module which has 5%, 30% and 100% output levels. They're cycles through by quick succession of half presses of the switch. Last output level used is memorized even when the light is switched off. The beam profile produced by has a mid-sized hotspot and spill beam, typical of other lights with similar reflector size. There are not artifacts as expected since a texture reflector is used, though there is a noticeable dark circle around the hotspot which is common in many XR-E based lights. Beam tint is slightly on the warm side when compared to sunlight white.

The 3-mode module only powers up when used with 2x CR123 batteries, 1x 18650 will not. You will require an optional extender tube which will enable it to hold 2x 18650. As you can see from the graphs below, regulation is maintained very well and stable at all output levels. Runtime is above average relative to the output it provides. The lights will start to pulse as the batteries get run down as an indication to the user.

The Good - Accessories and extras provided are great value considering the retail price. well-maintained regulation. Versatile variation in output levels.

The Bad - Nothing significant.

The Relative - Beam has a warm tint. Uses a forward push button or momentary/twist switch. Is able to tail stand. Modular design enables cost-effective upgrade options.
