12V IR spotlight

[AGZ]

Greetings
Can anyone recommend a 12V IR (850nm or above) spotlight with a long range (and reasonably priced)? I have tried the array types sold on ebay and the only give you 50m or so.
Cheers

"Reasonably priced" is an extremely subjectively variable term. Please be more specific so that you might get some reasonable answers.

How about a 1,400,000 CP 24V Xenon model from a Bradley. It's new/unused and comes with it's own new, 24V, 4/cyl. genset. It is NOT man portable!

Can be used white or IR.

you wont find anything like you looking for, there aren't any made, except for military target illuminators, but those are very expensive, and need external batteries. i was looking for one myself, no luck, had to build one from a scratch. it does give me few hundred yards beam easy, lights up night vision goggles, like a daylight, as well as any camera that picks up ir.

I need it to run on 12V (normal car battery). Do you have a link to this product by any chance?

It's in my shop. The genset is in a storage trailer off-site.

Thanks for the answer and very nice build project. I think I will have to modify a large hand-held IR flashlight like the T67 sold on ebay etc. There are also IR filters that fit a 5'' and 7'' xenon spotlight, but they seem to be made only in Australia and will not ship overseas.

too heavy for my needs... thx though

How about adding an IR filter/lens to this monster? https://www.fenix-store.com/fenix-lr80r-rechargeable-searchlight-18000-lumens/

i build mine in 2014, i do not remember t67 being on the market back then, at least IR version, i'd sure try it first, With the beam being in tightest setting, it is quite possible to reach 200m they claim, assuming the led is not a total trash. you may not need to modify it, but if you do, replacing the led and maybe the driver would do the trick.

looks good but quite expensive, and I didn't find a filter listed. is there one?

I have the T50, the smaller brother. It does have a beam of about 200m with the 850nm version. The only modification I need is to run it from the car battery. Will arrange some wiring and will use a DC/DC 12v to 7.5V 75W converter. What do you think?

I think you would have to have a glass shop cut it from a larger one.

What you want is probably only available as a "custom" and custom is never inexpensive. At least this way you're buying a good/powerful light from a reputable source. Adding a filter is not that expensive for what you end up with. If you go the ebay route (offshore), let us know how it works out.

That'd be a great way to end up with essentially no output at all - LEDs, unless they are designed to emit IR, have almost no output in the infrared part of the spectrum. If you want to filter a white light source to create an IR beam, you need to start with a source that has significant IR in the first place (so halogen, incandescent, xenon, etc.)

I don't know the output of their emitter, do you?

I don't know the output of their emitter, do you?

Page 11 of the datasheet available at https://download.luminus.com/datasheets/Luminus_SST-70X-W_Datasheet.pdf

By 780nm (the longest wavelength given), output has dropped to perhaps 7% of the peak on a W/nm basis, and much less than that when comparing total radiometric power below 780nm vs. above.

Nice work, you learn something every day.

Speaking of IR, has anyone else seen that video from "Styropyro" on YouTube called "100% Invisible IR death ray laser!" 😳

"100% Invisible IR death ray laser!"

Wow, this kid reminds me of someone I knew 60 years ago. He made thermite and blew a number of things up with homemade explosives. Oh yeah that was me. .

I'm betting he could build you a suitable IR emitter that wouldn't blind your targets. Ask him.
