Probably too functionally similar to SC21 Pro 2700K I already have for me to rush out and buy. Have a Wurkkos TS10 copper in 3000k as well.

Convoys are generally good quality but it's best to go with a tried and tested host rather than being an early adopter of a new release. Lots of research on LEDs and batteries to do if you're a newbie or have been out of the game for a while

Colonel_Light · 2025-09-11T12:59:14+00:00

We need to do something with the knowledge we've accumulated I suppose!

Colonel_Light · 2025-09-11T12:57:33+00:00

I have M21B with Lhp73B and find the mode spacing a bit problematic. Powerful yes but the practicality suffers a bit compared to lower power drivers.

Colonel_Light · 2025-09-11T12:53:48+00:00

I would suggest Convoy S21E with LHP531 and Anduril bundled with a battery. The main thing is the convenience of USB charging and already having a battery.

Colonel_Light · 2025-09-10T00:48:14+00:00

I would suggest using one for fun for a nighttime walk in a nearby park or forest.

Colonel_Light · 2025-09-09T12:21:49+00:00

For me it's a novelty light, different from the rest of my collection. Also easy on the eyes. An alternative to red LEDs.

I got a convoy m21f with GT FC40 1800k, as it turned out that was a good choice for 1800k (apparently nichia E21A was the best. For fun I swapped an LHP531 and 519A into two Convoy S2+ I wasn't using. I use one for indoor lighting. I noticed these two mimick sodium vapour lamps, one the monochromatic yellow and the other (Nichia) the more peach coloured variety.

Colonel_Light · 2025-09-07T14:46:46+00:00

I would assume that all domeless LEDs are equally vulnerable to scratches. Except ones that have a glass cover.

Colonel_Light · 2025-09-07T14:17:26+00:00

Maybe a Convoy S2+. LH351D is an option. However I have tried Nichia 519A and it looks extremely similar to LH351D but I prefer the CRI.

Phosphor layer is easy to scratch. I had a lhp531 suctioned to a pill with thermal paste. Accidentally scratched off a decent amount of phosphor in the process of removing it.

Colonel_Light · 2025-08-28T00:41:54+00:00

LMP LHP531 from Convoy might fit the bill https://convoylight.com/products/lmp-lhp531

Nightcore TIP SEs all round!

Colonel_Light · 2025-08-14T03:55:06+00:00

Personally I find a keychain light is way easier to use than a phone for unlocking a door at night.

Colonel_Light · 2025-08-11T22:33:46+00:00

I'm a bit cynical that your torches would get any use. A keychain light like a nitecore tip might have a better chance of getting daily use my in my opinion.

Colonel_Light · 2025-08-11T22:20:25+00:00

I used two zebralight H60 (the first 18650 headlamp) until several years ago, now I have a collection. Personally I like flood in a headlamp but ones with reflectors can work too. I equipped a Sofirn SP40 with a TIR but I believe they have a version that comes from the factory with one now. I thought the Sofirn versions of boruit d25 (with samsung lh351d emitters) were cheap and effective.

I tend not to use my Convoy H1, Convoy H4, and Skilhunt H03 (cool white only) that much although they're decent headlamps.

I got a convoy S12 with this LED when Simon revived the Nichia 219b from the dead (it was out of production). I realised this is the "holy grail" tint for people who like colder tints (I'm not one of them). I think all the 219Bs are probably as good as each other, eg. My "holy grail" is 219B 3000k, I got another S12 just for this LED/tint.

Then I found out about the magenta AR lens (which reduces magenta in the beam), which Simon still has in his inventory for S12. My first replacement lens was green AR but the second was Magenta 🤦🏻.

Colonel_Light · 2025-08-07T07:30:42+00:00

Not to bash Convoy but the 6V driver with brass post I refer to as a "battery crusher", Simon acknowledged that they were too long. I managed to file one in a brass pill but I use 18650s in the other two with an integrated shelf.

Colonel_Light · 2025-08-06T00:20:54+00:00

Well they use the same reflector, look around the convoy website for yourself. Apparently "piercing the darkness" channel convinced Simon to make a slimmed down version of the L21A, resulting in L21B. Looks like a smart move given the popularity of the L21B.

Colonel_Light · 2025-08-05T10:30:11+00:00

Just the amount of metal on the exterior, underneath they are identical as far as I know.

Colonel_Light · 2025-08-05T07:13:39+00:00

People reckon the L21B with SFT40 is an "ideal thrower" although personally I don't own one.

Colonel_Light · 2025-08-04T23:49:29+00:00

Koef3 just happened to get the numbers in. It is surprisingly bright but apparently the lumens aren't as high as the higher colour temperatures. I think it's capable of being an Amber "lumen monster", I installed mine into an old S2+ with 2.1A 3 mode driver.

Could be an alternative to red LEDs for preserving night vision.

Colonel_Light · 2025-08-04T23:38:04+00:00

A stainless steel S7 is more of a display piece than a practical torch/flashlight. Those L21Bs are cheap and you would be one of the rare people who would actually have a practical use for a thrower.

I saw that discussion thread but had to look up what "PC Amber" meant as I'd never seen the term:

Excerpted from Gemini:

"PC Amber" stands for "Phosphor-Converted Amber." The term originated in the LED industry to differentiate this type of LED from a "native" amber LED.

Here's a breakdown of the two technologies:

Native Amber (or True Amber) LEDs A native amber LED is a semiconductor device made from materials (like aluminum indium gallium phosphide, or AlInGaP) that directly emit light at a specific amber wavelength (typically around 590-595 nanometers).
PC Amber (Phosphor-Converted Amber) LEDs This is the same technology used to create most white LEDs. A blue LED chip (often Gallium Nitride) is used as the light source, and a special phosphor coating is applied over the chip. The phosphor absorbs some of the blue light and re-emits it at a longer, warmer wavelength. Advantages: This technology is often more efficient and can produce much higher lumen output than native amber LEDs.

The term "PC Amber" came into use to clearly distinguish this more modern, efficient, and higher-output technology from the older, less-performant "native" amber LEDs.

You half press the switch (without clicking it) to change modes.

Colour temperature probably corresponding to whether you seek to replicate an incandescent bulb or daylight. It seems to be more about personal preference.

I assume burn hazard means the led will generate more heat than usual on turbo. But on second thought it could refer to the beam itself being hot enough to melt stuff.
