The 2700K and 4000K SST20 emitters really are pretty good in my opinion. I’ve got a D4K with 4000K and a D4v2 with 2700K and the CRI is good and there isn’t a bunch of DUV so it’s really pretty decent considering it used to be hanks free emitter. Now it’s the NTG which is good, but they all have the rosy -DUV so it’s different than the SST20.
I think there was more lottery back then, some good ones, some bad ones. Nowadays the bad ones are consistently bad and the good ones are mostly consistent as well.
You know SST emitters are tint binned as well right? If some company cheapened out and got the one above BBL then yes it will be green but that applies to every tint-binned emitter.
As someone new to this, it’s really disappointing how gatekeeping people can be. It might be a helpful sales tool if the site shared info on each LED without assuming I know everything about everything up front.
Hey man, listen, I get it, I was the new guy in many different subreddits, and still am, but this subreddit truly is different. Every time I asked some questions that might be seen as stupid in other places, I got many more helpeful helpful than hurtful replies
The problem with chatgpt, and genAI as a whole, is that it doesn't actually know anything. It just sees its training data, and determines which words are most likely correct based on the prompt -- It's really just a fancy version of the autocorrect bar on your phone. Because of this, it has 0 clue if it's right or not, so if it's wrong, it will present it confidently. (See "ais think that there are 2 Rs in strawberry")
Btw, chatgpt is not wrong about the specs. It is a capable emitter, it's just that the tint is very green and most enthusiasts dislike it. It is perfectly usable as lomg as you don't mind the green tint.
In fact, it was my first emitter, as well. I've learned better since, but for a while it served me well.

Honestly? r/flashlight is one of the most helpful and friendly subreddits I've encountered.
There's a ton of misleading numbers and outright lies in the flashlight industry (lumen ratings and runtimes, for example).
Your situation is no different than getting bad advice from a friend. It happens, and I'm sorry it happened to you. But attacking knowledgeable folks because we're calling out the "friend's" advice is your decision.
This is why you don't just blindly believe everything some AI model tells you...it probably gets the specs/use cases from the manufacturer site which will obviously be biased. Otherwise it will probably take data from sst20 lights for general consumers (that often don't care about tint at all) and judge from good reviews that the led in the flashlight must be a good one. Especially if you want accurate information on some niche hobby, trusting chatgpt or any AI model without doing any research yourself is just dumb.
I have had passed here in two different threads and no one replied. I was downloaded over 30 times on one. I ended up just deleting them and trying to do some research on my own, but it’s very difficult if you’re brand new to all of this..
I’ve found that when it comes to flashlights if you just google your question either Reddit threads or budge light forum threads are likely to have an answer. If you’d titled a post here “what emitter should I get in a s21e?” People would definitely answer. It’s a really popular light and also one of the few widely available lights with a b35am option. That’s a Nichia emitter known for very good CRI and tint.
Ehh they kinda are great for that. They just have a nasty tint. I would say the sft70 or xhp50.3 is much better and they’re both also a 5050 footprint but it’s 6 volts so requires a different driver. What lights were you ordering from Convoy? The sst40 forces you into a worse driver on some lights like the s21e or s21g.
It’s not a bad emitter but I just don’t like the tint. In the s21e it forces into a linear driver that’s less efficient than the boost driver of you get an xhp50.3. I got a bunch of sst40 lights when I first got into flashlights because they make a lot of lumens but I just eventually figured out there’s other things I care much more about like having high CRI or nice tint or preferably both.
Picking an absolute worst is impossible. There's surely some rejected run of something cheap from a no-name factory that made it into a consumer product anyway.
When looking at things that a serious flashlight company has used as the main emitter in a serious flashlight recently though, I had to update the script that produces the tables in my reviews to be able to label the 0.0221 Duv of the Nitecore UHi40 "3x extremely green" - that is more than 3 times the tint deviation allowed by the ANSI standard for white light. CRI was an incredibly low 63, and efficiency wasn't good either.
The only thing it can do well is produce throw in a small optic, but other small round LEDs do that at least as well.
Whatever the odd LED was that came in the Javelot. It's a great thrower. But it has the highest DUV of any LED I've tested with my Opple (0.02something... it was up there! And only 66 CRI).
I don't know about the worst, but ones I've seen that I disliked very much - any SST20 above 4000k, SST40s never impressed me, Osram P9, I also wasn't a fan of any Nichia 219C's that I've seen. Oh, and whatever that crap is in the free/$3 Harbor Freight lights.
Probably ones that nobody here would even know the name of.
This is true. No-name led in a flashlight of unknown brand. I have one that is very blue.

Blue you say? My Lokilo says hello!
Well I agree :)) all the popular ones are… popular because they are good at one thing or another.
Wint-o-green lifesavers. They give off not nearly enough photons, it's annoying.
Runtime is poor but not bad for food
Early batches of sst20 5000k so green
I had a quad emitter with these and swapped them out for 2700k. So much better. The 5500k was gross.
The 2700K and 4000K SST20 emitters really are pretty good in my opinion. I’ve got a D4K with 4000K and a D4v2 with 2700K and the CRI is good and there isn’t a bunch of DUV so it’s really pretty decent considering it used to be hanks free emitter. Now it’s the NTG which is good, but they all have the rosy -DUV so it’s different than the SST20.
I mean, depends on what you're looking for - lots of people complain about green tint - but some of the nice looking LEDs are really inefficient
Also, if none of you lived through the CREE XR-E days and the luxeon III/V days, you don't even know green
The SST20 in a modern I have Fenix E06r is worse than the Cree and Luxeon days (Well except for that Gerber LX 3w that took 3xAA batteries)
Wow, that's impressive
I still have a muyshondt nautilus that I paid $200 for that has the the greenest XRE I've ever seen. My Luxeon V Surefire L4 was borderline cyan
I think there was more lottery back then, some good ones, some bad ones. Nowadays the bad ones are consistently bad and the good ones are mostly consistent as well.
sst40

They’re super green. I’m not talking about the sft40, I’m talking about the domed sst40.
I had to go check my order after seeing that. Fortunately I ordered the SFT40
You know SST emitters are tint binned as well right? If some company cheapened out and got the one above BBL then yes it will be green but that applies to every tint-binned emitter.
I’ve never seen a negative DUV sst40 6500k. I’ve got Sofirn, Wurkkos, Convoy and Olight. All green.
Because they bought the cheapest unsorted bins. Convoy has the BC tint bin which is 100% above BBL.

I've got a wurkkos wk03 with sst40 5000k that has a really nice rosy tint

That's what you get for trusting AI.
People are trusting chatbot advice to make decisions. That's an apocalyptic comedy skit we are living in.
MFW when the lie-crafting machine crafts lies

Fair, but they're not talking about that. They're talking about you getting your info from AI slop.
You could have done your own research, or just asked here on the sub.
The sub is helpful, promise. But don't expect reliable information from AI, that's all we're saying.
[deleted]
Well that sounds... par for the course. It's reddit, after all.
I'm sorry you experienced that. Don't let it get to you, though.

This is a very open community to questions. AI is in general very unpopular on reddit (rightfully so), I’m assuming that would be the downvotes.
If you want to compare emitters, people love posting beam shots on here, and also love talking about emitters, drivers, all of it.

It's true not much is explained on Convoy store. But gatekeeping? This sub is full of info and nerds eager to discuss endlessly about different LEDs.
Just ask people rather than chatbot.

They are cheap, efficient, and sometimes green. Their tint varies a fair bit, and often end up noticeably green.
Luckily you ordered convoys, so replacing emitters is very simple if you don't like them:
Find out which sized mcpcb your light use.
Order you new emitter already mounted to a correct size mcpcb
Open your light.
De-solder the black and red wires connected to the mcpcb
Swap with new one
Solder wires back
Done.
Literally only requires a soldering iron and some very basic soldering, and a screwdriver to unscrew the screws golding the mcpcb down.
I have two spare 519a sitting around.
Ehh they kinda are great for that. They just have a nasty tint. I would say the sft70 or xhp50.3 is much better and they’re both also a 5050 footprint but it’s 6 volts so requires a different driver. What lights were you ordering from Convoy? The sst40 forces you into a worse driver on some lights like the s21e or s21g.
S21e is one of them. The other was an s2+
It’s not a bad emitter but I just don’t like the tint. In the s21e it forces into a linear driver that’s less efficient than the boost driver of you get an xhp50.3. I got a bunch of sst40 lights when I first got into flashlights because they make a lot of lumens but I just eventually figured out there’s other things I care much more about like having high CRI or nice tint or preferably both.
Sorry for that. But remember, the least liked here is still waaaaaaaay better than the stuff we daren't even mention.
Plus, if you can solder, Convoy sells boards with fifferent emitfers to swap in in the future.
BTW bravo going Convoy.
If you don't mind the green tint it still quite efficient at low/medium currents (lm/W).
For sure, my Olight Baton 4 is one of my favorite lights, but the green SST40 is gross.
The big Olight Prowess is packed with like six sst40 and it’s so gross. I only use it for the awesome lantern on the underside.

The ones which come in cheap zoomies. Horrible blue tint.
Osram
P9is one of the worst I've seen in a flashlight (Lumintop EDC15).Edit: Actually I don't know which Osram LED they use in the EDC15 but it's very green. P9 is what's in Tool 3.0 and it is more neutral.
Whatever the odd LED was that came in the Javelot. It's a great thrower. But it has the highest DUV of any LED I've tested with my Opple (0.02something... it was up there! And only 66 CRI).
Then the Osram P9. 🤮🤮
The one that doesn’t turn on when I need it
Story of my life...
I don't know about the worst, but ones I've seen that I disliked very much - any SST20 above 4000k, SST40s never impressed me, Osram P9, I also wasn't a fan of any Nichia 219C's that I've seen. Oh, and whatever that crap is in the free/$3 Harbor Freight lights.
Whatever emitter they used in olight baton 4, it's the greenest tint I've ever seen on a light, but I hope maybe I just got a "bad apple"!?
I actually swapped the baton 4 emitter with the one from a fenix e18r v2, it's so much nicer in comparison!
Olight is gonna Olight
I've got a xhp 70.2 light that's SUPER green tint. Probably not the worst led ever but it's my least favorite tint anyways
Well... I ordered this battery the other day...
From what I've used, it's a tie between the SST-40 6500K in a Fenix E35 v1 and the XHP70.3HI R9050 5000K in the Zebralight SC700d HI...
You will know puke green like you've never known it before by seeing these 2 emitters try to out-vomit each other on a white wall.
