By: perfectful The entire light if finished in black Type 3 anodizing. The second part of the SR90 is the battery pack which houses six 18650 cells. Surprisingly, it actually weighs lighter than the head assembly. The battery pack comes with a screw-on protective cap, handy when the battery pack is kept in storage. Threads between the battery pack and head mate nicely with no cross-threading or grinding. The exterior of the battery pack is covered in a a series of rectangular- When a light has a "low" mode of over 300 lumens, it should be a good enough hint of what it's capable of. As far as LED's go, the SR90 puts out an extremely large amount of light from a single emitter, all thanks to the new SST-90 LED by Luminus. While the official data sheet shows the SST-90 capable of a maximum of 2200 lumens, practical output measure after considering optical and heat losses still puts it at an impressive 1382 lumens. The user interface is very simple, holding the switch down cycles between the high and low levels (alternates in one second intervals). Activating/deactivating strobe mode is done by simply double-clicking the switch on either output level. High/low output levels are memorized even after it's switched off. The beam profile output by the SR90 is a tight spot designed for optimum throw. The spot is well focused with some subtle darker areas within it, though due to the sheer intensity, it's practically unnoticeably in practical use. The corona just outside the hotspot has a four-point oval shape which is due to light reflecting off the LED's base and is not a defect in any way. Beam tint is very close to sunlight white, perhaps just slightly cool around the spill beam but warm around the corona. Relative to its output, runtime provided is average. This is to be expected since efficiency decreases as LED's are pushed harder. One thing to take note is that the light with instantly switch off when the battery is depleted with no noticeable prior dimming. This behavior is common with light running on multiple li-ion cells meant as a protection mechanism. The Good - Huge amount of light from a single LED. Well built, clean fit and finish. Easy charging solution. Handy battery indicator. The Bad - Hefty size and weight. The Relative - Beam tint close to sunlight white. Toggle switch button doesn't allow for momentary activation. Is able to tail stand. Includes useful carrying case and accessories. # # # Www,lightake.com,a online shopping company ,have plenty of gadgets you can choose form ,like flshlight ,laser and other products! End
