good 365nm uv, portable

[techwg]

hey guys, whats a good uv flashlight, be it keychain, or fenix E0 style that is around 365nm so it will detect more things that the cheaper 400 <> nm

Arc UV perhaps?

I was thinking the same. I like my ARC AAA UV, although I must admit it's not as bright as I expected. I have another 3AAA UV LED that's much brighter. The color quality on the ARC is superb. The build quality is legendary.

ARC has excellent customer service as well.
Buy the ARC AAA UV, you won't be disappointed.

Im looking for the lowest wavelength, beacuse i hear they can pick up more things. Kind of hoping for a little bit of throw, so theres no need to be right on top of something. arc can do this at a range and still offer good luminescance?

 

[tsask]

The ARC UV isn't known for throw, yet the color IMHO is the best.
Having it on your keyring you can have some :sick2:interesting EDC experiences.

Don't know about the Arc UV or other branded versions but I went through a UV luminescence quest some time ago and found this to be very good while not being that high on visible light.

Aluminium 28 Ultra Bright 370nm UV (Ultra violet) LED Flashlight 3 x AAA

Lowest I've seen is 395-385nm

The Inova X-ones are 395, not sure what the X5-UV is at.

Does anyone make a UV emitter that low for non-specialized use?

edit: Hmm, the Photon lights have a 370nm emitter.

So the wave length is low enough to prove more useful in special circumstances than a cheaper one? Im kind of hoping for 365nm or something which will detect more things and generally be more useful than the higher nm range.

Ignore....I'll post my question up in LED forum....

Its ebay so who knows about quality but its advertised at 385nm.

For a while, Peak in this forum had talked about offering a couple different wavelength choices for UV led. You may want to give them a call to see if they have any left.

Nichia makes a high power one at 365nm, and I have a light with one that was built by Wayne at the sandwich Shoppe. AFAIK the LEDs are ~$90, but they will sell them individually. You may be able to commission the Shoppe to build an Aleph 19 with one.

365nm will cost you an arm and a leg. 395nm makes a lot of things glow if you have enough of it. For economy, I use a Cree high power UV driven at 500mA. I hear they don't make them anymore so your next best bet is the Nichia at close to $100 a pop per Larry above.

 

[techwg]

i have ordered one of these, just cos i would like to know if its any better than the 3xaaa cheapo i got from DX

The Nichia NSPU510CS might be a good compromise between cost, wavelength and ease of installation. It's a standard 5mm package at 375nm.

I used an older version of that for the UV mod in my SF A2, I wanted to get the 510CSs but it looked like too much work/cost (minimum order is Q100, they don't really like to talk to "people" anyway) and I was lazy and used what I had. I'd jump at the chance to upgrade if I could get a smaller quantity.

DealExtreme has some UV LEDs, but when I contacted them for a data sheet to determine output and wavelength they were, well, lets just say I got the response I expected.

 

[techwg]

and do you think 375nm is good? the one i have, let me show you what i already have. http://www.dealextreme.com/details.dx/sku.4014

thats the one i have already, do you think the pen one i listed in my other post, being 375nm will be better than this?

Peak makes AA/AAA lights with the 360nm UV LEDs. I have a Kilamanjaro (single AA light) it has 7 360nM UV LEDs and works very well...built like a tank. I ordered mine with the normal power level and run a lithium AA since I don't use it very often.

Give them a call and they can make 1, 3 or 7 360nM LED lights be it AAA, AA or CR123A. Have a great weekend!
