To activate the COB light, simply pull the head from the body. The COB light will turn on directly when you start pulling, even with only 3 millimeters moved. That means that the light will be turned on, while covered for 95% by the flashlight body. Nebo included a proprietary ICR 18650 lithium-ion battery, with a total capacity of 2200mAh. This is actually quite small for a battery nowadays. I don’t know why they couldn’t choose a 3000mAh or just use a 3500mAh battery. Since the light shouldn’t be pulling many Amps, a 3500 mAh battery would have been fine. Having 2,000 lumens is not bad, since that’s brighter than about 95% of all the flashlight currently on planet earth. It’s interesting to note that the CCT is supposed to be 10000K and extremely cold, but in person it’s not really blueish. A very impressive way to reduce the loss of light is by using something like a Wavien Collar. This will ‘recycle’ the light, and the output loss is only about 10% (I measured 7.6% loss on the Microfire Excalibur H20, and 5.4% on the H8). But those are quite rare.
Like with many zoomies, the convex lens is not protected by a flat glass lens. That would have been preferred because a convex is more likely to damage and more difficult to replace than a simple glass lens. There were a few very small spots on the anodization in some tiny machining marks around the light, but nothing to worry about, if you are going to use it as a work light. It’s not meant to be a shelf queen, and will also never be one.
As well as the white light, the COB LED has a constant red light output and red flashing output. Red light is useful for night reading, animal spotting and preserving night vision, and the flashing red light is good for attracting attention, making it useful for in the car or on camping trips. I’d like to point out the weakness of normal zoomie flashlights, and that’s the loss of light when the beam is focused into the tightest spot. The focusing lens is far from the LED, and a lot of light from the LED will be lost because it bounces around.
The switch is shrouded and lit when the light is turned on, and the color indicates the battery level. The following colors are available:It would have been nice to have some more battery level indicators. Having only 1 indicator for 100% to 25% is not very handy. I’d rather have more battery levels, like 100-75% 75-50% 50-25% 25-10% 10-5% <5% During the lumen test, I noticed that the Low mode drops a few lumens every few seconds. It’s not like it’s a smooth drop like you see with other lights, but short instant drops. I haven’t seen this behavior before, as far as I can remember. The Lowest output starts at around 190 lumens, drops to 148 lumens in 30 seconds, and 66 lumens in 1 minute. It’s interesting to note that the light drops in steps, and not gradually. That’s kind of hard to tell in this graph, because the measurements are done every 5 seconds. You’d have to look at the 10 minutes graph to see this. The runtime is supposed to be 10% of the initial 30 seconds reading, so that means about 6.6 lumens. That’s about 16 hours. At 17h06min the light finally turns off.

Press and hold: ramping brightness up and down. It will blink at the highest and lowest output, but if you keep pressing the switch, it just continues ramping up and down By default, it turns on in the White mode. But if you press the side switch, and slide the body, you can get red light directly. You can see that it takes 6.5 minutes to reach 1000 lumens…. which is actually a really good performance! And 11.5 minutes to reach 500 lumens. Most flashlights drop below 1000 lumens within 3 minutes… All output numbers are relative to my homemade Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.Bernard is known for bringing everyday carry out of obscurity and into the mainstream, having been published or featured in various publications such as GQ, TIME Magazine, The New York Times, VICE, HYPEBEAST, Outside, and many others.

He stays on the pulse of the EDC industry by attending trade shows, participating in online interest communities, and actively engaging with fellow gear enthusiasts on social media. To activate the SLYDE KING 2K's signature COB work light, simply extend the flashlight out by pulling the top and bottom of the light. The work light will activate automatically straight into high mode, so be careful not to look directly at the light when opening. In this mode, the light is 500 lumens, shining for four hours. You can also dim the light in this mode by holding down the button as before with the flashlight. This mode is 50 lumens shining for 24 hours.
