Got this inexpensive thermal camera (which is also a multimeter!) for a review recently. Although it is not a high-end device, the resolution of 32 × 32 pixels (with high resolution camera overlay) is absolutely sufficient for many applications – and a lot of fun as well! Finally I'm able to see how my flashlights warm up.

Flashlights in the pictures are: Skilhunt EC200, EC500 and M200 V4

Review: Skilhunt H200 - an all-purpose right-angle headlamp with white and red

The Skilhunt H200 is a midsize right-angle flashlight and headlamp with two white LEDs and one red, powered by an 18650 size Li-ion rechargeable battery recharged internally with a USB-magnetic cable. The right-angle light is perhaps the most versatile category of flashlight since it can be used as a handheld flashlight, a headlamp, clipped to gear or clothing, or attached to surfaces with its magnetic tailcap. Someone who wants one flashlight for all use cases will be well served by a light like this, as long as none of those use cases involves illuminating things much past 100m.

OP reflector, FFL707A from 1800K to 6500K, LumeX1 driver with Anduril 2 but no USB-C charging this time (to minimise size I think, looks really compact).

(Usual banner saying they don't take orders from the US)

For background, it's hard to make a flashlight that works well on both AA batteries (0.8-1.7V potential operating range) and 14500 Li-ion batteries (2.8-4.2V operating range) given that white LEDs need about 3V.

For a long time, companies would make lights designed for AA using a boost driver that increases the output voltage, do just enough so it wouldn't burn out with excessive input voltage, and say that 14500 size Li-ion was "supported". Max output would, indeed be brighter, but low modes were usually far too high, and the flashlights could easily damage batteries that didn't have over-discharge protection.

The Skilhunt M150 was one of the first lights to do a substantially better job. Using a Li-ion battery, it sent the power through a variable-output linear regulator so both battery types could have reasonable modes, and it would shut off to prevent over-discharge. Several competitors use a similar approach today, but linear regulators are inefficient; they just turn the excess voltage to heat.

The ideal solution is either to use a higher-voltage LED configuration and boost the output voltage for both battery types, or to use a driver that can both boost (increase) and buck (decrease) voltage efficiently. The Emisar D3AA is the only light on the market doing AA/14500 with a high-voltage LED configuration (three in series for ~9V), and I believe the new M150 will be the first one using the buck/boost approach (though it's possible Zebralight has done it in the past).

I'm getting my manager at work into flashlights. He's got a pair of D4's on the way, and I told him about my buddies D18. He liked the idea but wanted to see it. I showed him today and he was blown away, wants to keep it in his jeep when off-roading.

But I just realized Hank doesn't sell the D18 anymore...

Is there another light that would fulfill the same popcan sized wall of light that the D18 does? Or is anyone sitting on a D18 they're willing to part with?

Price is a factor, preferably around that same hundred dollars, but I'll pass along options even if they're more expensive.

Anduril is also preferred, but not required.

Summary

The Cyanlamp M12R from Cyansky combines many good ideas: A spotlight for throw, that can also be used as a headlamp when clipped to a cap. A floodlight that evenly illuminates at close range. There are also RGB LEDs with various effects and work great as a beacon or marker. The flashlight can be attached either with the large clip, an eyelet or the integrated magnet. It can also be switched on and off with a simple gesture control.

However, there is still room for improvement in the implementation: Starting with the cool white light with low CRI, the unattractive color shift of the spotlight, to the simple driver that cannot keep the brightness constant. In addition, it doesn’t indicate whether you turn on the spotlight or floodlight.

Sometimes a flashlight just isn't enough. The Flying Sun 1000 drone system was designed with that fact in mind, as it uses 288 airborne LEDs to light up the night like the alien mothership from Close Encounters of the Third Kind.

It's almost the same as v1.0. Surprisingly complex circuit. 13 minute video.

Review: Convoy 14500 Shipping Light - the best value in flashlights today

The Convoy 14500 Shipping Light is included free of charge with the purchase of a 14500 battery from Convoy. It's a great value - one might even say an infinite value.

Summary

With up to 600 lumens, the tiny Nitecore TINI3 achieves an impressive brightness for its size and with the adjustable color temperatures it adapts to any situation. The practical OLED display provides information about brightness, battery level and remaining runtime. Thanks to its small size and a weight of just 20 g, it is barely noticeable on your key ring, but is always ready for use.

It would have been nice to have an (optional) automatic lockout to prevent the flashlight from turning on in the pocket if you forget to lock it manually. Time will tell whether a glass would have been useful to protect the TIR optic. Other than that, the TINI3 is pretty much perfect.

Emitter swap: Luminus SFT40 4000K high-CRI into a Skilhunt M200 v3

Kaidomain sold a handful of these LEDs last fall and I made the mistake of buying only two. Rumor has it they were engineering samples, and may never be produced in large quantities.

Unlike the 3000K model, efficiency is not much worse than the low-CRI SFT40. I see 1400 lumens from this flashlight, and 250m throw. The increased throw over the original 519A is most welcome. Color rendering index is 92, and R9 (deep red rendering) is 71, which are a bit lower than the 3000K. That's probably responsible for the higher efficiency.

I noticed a broken bond wire after I took this picture. I'm glad it has extras.

Mainly bought it for astrophotography, it’s also not bad for night book reading at home for its really low moonlight mode.

Whats todays edc and led/tint combo?

Review: Sofirn SC13 - a budget EDC light with great color quality and USB-C charging

The Sofirn SC13 is a very inexpensive pocket flashlight powered by an 18350 size rechargeable battery with a USB-C port on the flashlight body for charging and a magnetic tailcap for hands-free use.

NLD: red

After reading the post from @solrize regarding potential benefits of far-red light on cellular respiration, I bought a Convoy S2+ with the 660nm Luminus SST-20. It's red. Very red.

The Vapcell N40 18650 battery has impressive capacity

I tested this N40 I bought from Convoy at 1A on the Opus and got 3901 mAh. I expected a bit less since advertised capacity is usually at very low current, so I am pleased with this result.

Summary

The Nitecore EDC23 flashlight has been my everyday companion for a few months. The Nitecore EDC29 is the perfect alternative when more light is needed. The two UHi 20 MAX LEDs are not only quite bright at 6500 lm, but also produce a wall of light in Lumin Shield mode. I also like the great UI with two buttons and the “Rapid Lock” lockout using a slide switch.

Given the compact design, it is not surprising that the flashlight heats up quickly and cannot maintain the high brightness for long. In the lower levels however, the constant current driver keeps the brightness pretty constant. Unfortunately it is not possible to choose freely between the wide and narrow beam for each brightness level. The permanently installed rechargeable battery can also be seen as a disadvantage.

Just thought it would be cool to have a thing on Matrix for this community as well. There's a discord server, but you have to have your phone number attached to your account to be there now
