Victoria Posted October 16, 2007 Report Share Posted October 16, 2007 Remember our TeeJay recently said I should get an UV LED torch/flashlight, the better to get the brightest lume on my PAMs? Check it! Photo #1 UV Led torch (140 "bulbs" strong) brought out a strange pattern, never before seen on my Fiddy using either ambient or artificial light. The hands seem Superluminova'ed and Hulk green, but seemingly the light blue numbers and markers (?!) are not! Photo #2 LED torch held on the DSN Fiddy for the same length of time, and under the same conditions to take the shot. The green is evenly coloured throughout, with not a hint of blue, and may I say, MUCH brighter than the UV LED torch. Lasts longer too. Wow. Is this normal, a fault, or simply chemical properties brought out by one torch, and not the other? Quote Link to comment Share on other sites More sharing options...

Logan Posted October 18, 2007 Report Share Posted October 18, 2007 Its a property of the UV paint. It glows as a result of primarily UV exposure rather than visible light. Sunlight does a great job of charging the lume, as it sunlight contains a lot of UV light. Wear a rep in a night club with a UV light and you'll be able to read it from across the room.

TeeJay Posted October 18, 2007 Report Share Posted October 18, 2007 Wow, those are really varied results... Out of curiousity, for the first shot, was the lume still being exposed to the UV light? Was it a UV bulb used to reveal 'invisible' security markers, or was it a definite 'black light' bulb (not sure what, if any difference there is, but bear with me...) When I used a 'UV Revealing' bulb, I got a powerfull green effect, as shown previously. If, however, I put a watch near a 'black light' bulb, (like in a novelty shop) then I had the same blue/green result as you saw, but, it only lasted while the lumes were directly bathed in the 'black light', once they were back in normal light, they just had the strong green glow... Very interesting results indeed You might like my new wrist shot which I'm about to post Quote Link to comment Share on other sites More sharing options...
Steve G Posted October 18, 2007 Report Share Posted October 18, 2007 I too noticed the "black light" effect. While at Disney World last week with the family I had a few watches in rotation. A lot of rides there use black light inside their displays and such. My watches glowed the best I've ever seen them, while under the black light. My BCE the hands were much greener than the markers, I suppose indicating more lume applied to those areas. Very interesting. Quote Link to comment Share on other sites More sharing options...
Victoria Posted October 18, 2007 Author Report Share Posted October 18, 2007 Wow, those are really varied results... Out of curiousity, for the first shot, was the lume still being exposed to the UV light? No, not at all. I went to the en suite toilet, which has no window, and shone the torch for about 1 minute. Turned off the torch, and took a quick photo in complete darkness. Same procedure with the bottom photo. Was it a UV bulb used to reveal 'invisible' security markers, or was it a definite 'black light' bulb (not sure what, if any difference there is, but bear with me...) Let me try to show you a photo of the torch I bought (on eBay). What you wrote is a bit too techy for me. EDIT: Oops, not 140 UV lightbulbs. Just 41! "UV 41 LEDs light burn life of around 100000 hours 2 modes of operation: Press on/off button ONCE - 21 LED mode / Press on/off button TWICE - 41 LED mode Aluminium body Ideal as a pocket flashlight Can act as money detector Twist for constant on/off Powered by 4 x AAA batteries (not included) Size: 143 x 53mm" I used mode number 2, the one with the most lightbulbs. Looks exactly like this: When I used a 'UV Revealing' bulb, I got a powerfull green effect, as shown previously.

Shame it has to go back, but there you are. The usual rep watch owner merry-go-round. @All who replied with info: THANKS! I begin to understand why the variations occured. Any more first-hand info would be lovely. Quote Link to comment Share on other sites More sharing options...

That's really interesting that your markers and hands still flouresced different colors once the light source had been removed, I guess it could be down to slightly different lume materials being used on the hands and markers (whenever I see photos like this, it's always the same color seperation, ie dial/markers blue, hands green) The torch itself looks fairly standard, so I'm at a loss to explain the different results, but the UV light I've used (a Doctor Who Sonic Screwdriver) always produces an even green glow after charging. I have to admit, I do rather like it Although not quite as much as the 111h I'm not too keen on how the domed crystal distorts the edges of the dial and reflections, where the 111h crystal provides a more uniform view... That said, the 127 case, being 'less blocky' is very nice, and more 'subtle' than the 111h. I'm still waiting on a reply from my dealer, but I'm hoping I'll just be able to install a new crown guard rather than having to totally replace the whole watch...

sssurfer Posted October 19, 2007 Report Share Posted October 19, 2007 If you use a black light the type they use on dancing rooms I suppose you get the best effect. I tried with an UV lamp emitting in the far UV spectrum (that lamp that looks purple and barely emitting any real light) and, besides it is dangerous, its emission in the purple visible spectrum was sufficient to definitely alter the color of the dial, case, hands, everything. Not good for taking pics. Quote Link to comment Share on other sites More sharing options...

I too have charged my watche's lume up before going out; mea culpa...! Quote Link to comment Share on other sites More sharing options...

I too have charged my watche's lume up before going out; mea culpa...! Oh forget it. When I'm about to go outside, since my torch is right next to my watch cabinet, I immediately grab it and place it on my watchface for 5 minutes! Lady with the Lamp. Yes, vanity. But it looks SO COOL! Quote Link to comment Share on other sites More sharing options...

But it looks SO COOL! Practical too Not much point in a dial having luminous markers, if, when you're exposed to darkness, it doesn't actually glow Sure, holding the dial an inch from your eye and squinting works in a pinch, but it's hardly ideal Quote Link to comment Share on other sites More sharing options...
