Made a mistake buying a 365nm UV light.

Now I gotta clean my house better. :green::eeew:

Either that or change the bed sheets more often.

I was going on a business trip for final acceptance of some circuit boards we were having built. I took a 9 inch tube UV light with me to inspect the conformal coating. The light was packed inside my luggage for safe keeping for the trip. Once I got to the hotel, I plugged the light in for giggles, and the bed comforter lit up like a Christmas tree.

No more Raddison Suites for me.

My sheets looked fine actually. It looks like I really should eat at the dinner table more often than at my computer.

Hotel rooms are the worst! On a school trip to DC one of our teachers used a keychain UV light as a joke... he ended up having to ask managment for new sheets, towels, etc... eww :shakehead

I will be in London at the Savoy, I will check there, if they have a problem, well, I dont even know what to say?

Red,

Did you get my email?

Purchase one of the Nitecore P20UV lights to take with you. Small enough for an edc kinda of light with enough power for the UV function.

My advice is not to check the rooms, check the aircraft you are flying on. I have traveled most of my life, and am winding that down. Never kept frequent flier miles because I never wanted to go any where unless it was business, and someone else paid the way.

It would have been in the multi millions of miles. I was able to travel when people were elegantly dressed, refined. educated. I still wear a beautifully cut suit, and french shoes, and cuff links, you get more respect from the TSA, and foreign authority, And that included the Soviet Union, after buying Vodka for out security escort, all was well. they really get hammered in Russia, I liked that.

I had a horrifying fight with the British Metro police at Heathrow over a Spyderco and when I told them, and this is true, we were just married in the United Kingdom, the officer said 'well that's all good, gave me the knife back, and said 'have a nice flight Sir.' That was 20 years ago this May. What wonderful days when every passenger at least showered despite being dressed like a rummage sale, and something happened to their comb and brush.

My passports have so many stamps in them, at customs they think i'm up to something...

My advice is just stay home.

PS...That fight in the UK...would not Have Happened in the USSR. Plus Aeroflot to Malpensa, Milan, Italy was scary on a reversed engineered Boeing 727 to a non stop TWA Boeing 747 flight was much nicer, to LAX- Los Angeles, and the a private Gulf Stream to Palm Springs, CA.

No, I did not Chief, send it again. thanks.

Oh no, I'm afraid mine is arriving on Monday... Now I'm not sure if I want to go pick it up from the post office

Some marks on bed sheets despite washing will still show up. Hard to tell what makes them but even the detergent can cause suspicious blotches

Brightners in detergents will glow really bright, maybe it is that.

Did you go for the Convoy S2+ with Nichia UV? That thing is a freaking beast and illuminates all sorts of stuff that I had not previously imagined would be around, well, everywhere.

Yep. :shakehead

Remember to use eye protection when using UV emitters.
Only a tiny portion of the emission energy is used to flouresce what you do not hope to see on sheets.
Reflected UV can be a hazard, so you do not need to be looking at the business end of the UV flashlight to get in trouble.

They are great for charging glow in the dark things too.
405nm emitter

Yes, important safety tip. Now, I had an eye exam and the Dr. knew quite a bit about UV and told me any polycarbonate [sp] glasses protect all forms of UV even 365nm! Is this true?

+1 good tip.
Thanks.

Apologies for the thread drift, but I could actually do with a good UV light for detecting hydraulic /fuel /oil leaks. What would be the best nm range for this and of course the best light that's fit for purpose .

Hi Ned,
Yes, in general, polycarbonate lenses have superior UV protection, however, wrap-around style UV safety glasses provide better coverage against leaks from around the lens.




Things to note about high output UV lights:-
▪ Most of the tasks we flashaholics use UV flashlights for are likely to be close-range work - Inspection of leaks and stains, spotting scorpions, curing Norland. Couple that with the inverse square law and you could be exposing yourself to harm if you do not protect your eyes.
▪ UV emission is in a band, so for example, a NiteCore CU6 or P20UV may be advertised as 365nm output, it is emitting with a peak output at about 365nm. There will still be some emission at other wavelengths in the neighbourhood of the peak. For higher output emitters like the '3W UV' emitter used by NiteCore and some of the P60 drop-ins, this 'spill' emission can still have significant energy (HEV/Near UV).
▪ The energy output of many of the higher energy emitters demands a lot of care. In general, the better quality UV emitters emit very little visible light.

Here's a great YouTube video by hugo2x that demonstrates the difference in the emission energy (If I'm not mistaken, the Nichia UV emitter used in the Nailbender is about 0.4W).

The usual practice would be to introduce certain types of dyes into the fluid system. The optimal wavelength for UV fluorescence is tied to the dye used.

I do know that Fluke makes a AAA inspection flashlight - the Fluke RLD2 HVAC/R that was designed for HVAC technicians. That uses 395nm UV LEDs.
