The There Are No Stupid Questions Thread

The GT-FC40 (19.1mm2) LES is 2 times the area of the B35A’s (9.7mm2), so between the two I would go with the latter, even though you could crank up the power on the FC40 to compensate.

However I would rather go with the XHP50.3 HI, the LES appears to be around 8mm2 and it will take much more current than the B35A, Mouser has a 4500K 90CRI HI in stock.

Edit : I see the question was rather about hosts, sorry :smiley: , no answer for that except that B35As produce a small eggyolk effect with SMO reflectors in my experience, it’s fine with OP, clear TIRs can also do that, and may require turning the height of the optic to eliminate it. (sometimes at the cost of a bit of throw)

I’m receiving some tomorrow and will do some color testing with a spectrophotometer.

@ CRC:

That overly lengthy post is TL;DR. Trim your responses down. If you have to, make multiple responses directed at each post and use …/ for shorthand (especially for Correllux’s response(s) – he tends to get carried away).

When ordering a 2-channel light from Emisar/Noctigon, Does it matter which emitter you choose for Channel 1 and Channel 2? Does one channel become the base or default channel? So if I want to ramp from warm to cold do I have to put the warm emitters in Channel 1?

Anduril high/turbo question.
I will be getting my first Anduril lights (DM11 & D4V2 UV mule) and after seeing the UI sheet and some videos I would like to use the simple UI (for now).

If a light is advertised as 5A or 7A or 9A is this the ‘turbo mode’ or the ‘high mode’?
If it is ‘turbo mode’ then what % of that is considered ‘high mode’?
if it is ‘high mode’ then what is turbo mode?

This is probably an easy question but I couldn’t find any answer in the videos I saw.
If there is a link that explains this and other basic Anduril driver questions, please offer link.
Thanks!

Remember that these aren’t rules anywhere, and just suggestions based on opinion.

Feel free to post as long or short as you want and as concise as you want to be, or not. Sidney might not read your longer posts but some of us have short attention spans.

Oh look! A butterfly

Huh? You endorse this repetitive posting?

I know there’s a few people that are really outspoken about it but it doesn’t really bother me either

Long posts should be no problem…evaluate whether it is information you need and then either read it or don’t.

CRC quoted post #1594 in its entirety – only to comment “Wow, thank you for all the valuable information and lvideo links.
Sorry for the late reply, and im only just seeing this now so I still have to check it all out…/”
(there are more of his responses but they get buried).

Then added Post #1601 xevious: “Another good channel is Afrotechmods…/”

Surely this could have been condensed in a smaller package without losing its response.

It is not the lengthy responses of the members that are at play, but the attachment of such to voice an opinion.

Take for example that last one. Could have been shortened to:
@ xevious: regarding Afrotechmods – Thanks for the video and channel suggestion…/

Now, I’m not condoning Correllux nor xevious’ posts, but the re-iteration and the mishmash that ensures.

Just a pragmatic observation.

Yeah, I don’t see an issue with this at all. Additionally, if one quotes a post, they are preserving a copy (in their own post history) whereas in theory the original posted could change or delete their post.

Especially if the quoted conversation is relevant to the post, since this forum software doesn’t provide links to the original quoted posts, it prevents having to scroll back (sometimes several pages) to read portions of the original conversation for context.

Today I reflowed a 219B to the Sofirn SC11 (4x AA). I also put in a spare FC12 LED and board into another SF11. It barely fits into the reflector and I was able to reuse the screws to hold it down. (Beginning’s luck) The beam looks about the same as the Wurkkos FC12. It works and has no problem so far on both SC11. I did a runtime on the 219B and when I realize the SC11 a 6V flashlight, isn’t it? I was using fresh 1.3v Eneloop and it ran for 60 mins to empty, the body heated up about the same as the S2+ with 219B. Does that mean it the 219B will work at ~5.2v for a while until the Eneloop drain to 4.8v steady for a while? Maybe I am in the clear?

Will I run into a problem with the SFT40? It works so far and it’s been running for 30 mins.

219b and SFT40 are 3V LEDs. The driver is a buck driver which reduces the voltage of the four cells (which are in series) to the forward voltage of the emitter. It should work fine as long as the combined voltage of the cells is > ~3V. So even if all four cells are almost dead (~0.9V) it should still be able to drive the LED just fine (as long as low voltage protection doesn’t kick in before that).

Hope I understood your question correctly.

Can LEP technology be used by a nation as a weapon?

I guess it could be use as a dazzler. Like a distraction or temporary blinding device. Other than that, I don’t think so. It wouldn’t really provide a huge tactical advantage to a nation state, unlike other devices like microbolometers (thermal cameras) which are regulated as weapons in some countries.

I am imagining a large one, perhaps installed in an artificial moon or a satellite that could be directed to an enemy state.

But why, though?

Sure, a laser could be used as a weapon. Not sure how much power you would need to do that from space, but why put a phosphor in front of it for weapons use? Doesn’t make any sense.

Drive people to kill each other with ugly green-tinted light?

Thanks for the explanation
