How much surface area and depth are you trying to cure?

3 Joules/cm² is quite a bit of energy for a battery-powered device; you'd probably be better off using something powered by the mains.

Just enough surface area to fit a 1.5mm x 5mm trit vial into a bezel.
 
I've been using Norland 61 to mount the same size trit vials as you and good ol' sunlight has worked like a charm. Direct light cures it nice and hard in about one and a half to two hours.
 
Hi all,

I am desperately seeking a light to cure Norland 61. I've been looking for the Nichia 365nm high power LED but it just seem unobtainable, plus it would be very expensive (around $100 for the emitter if my information is correct?).

I don't have access to direct sunlight in my appartment, plus here at this time of the year the weather sucks and I don't want to wait a week for the sun to show up and cure my vials :shrug:

So, what can I do?

I have found this little device http://maxmax.com/aUVLedLights.htm
But I have no idea if it will be powerfull enough to cure Norland in less than a minute/couple of minute. So far it is the only affordable 365nm UV source I have found. It's not cheap though.

Anyone know if it will work?

Thanks!!
 
I use a simple & cheap UV curing lamp for fingernails (from my gf :whistle:).
Works great, N61 hardens in seconds with this.
 
not sure, try ebay search for uv lamp or nail art or something like this :naughty:

edit: for example this not exactly what I have but works similar but I think a single 9W bulb instead of 4 would do the job, too

the link doesn't work :shrug:

are these UV lamp have a fluorescent-tube-like look? Like the one usually sold as "dark light" to check money?
 
Sorry for the non-working link, it's ebay item number 350106521367 (put it in the ebay search)
 
"Unfortunately, access to this particular item has been blocked due to legal restrictions in some countries." I still can't see it :(
But I've found it with google. So, basically this is UV bulbs, right?

Strange because I have a UV lamp but it doesn't cure Norland properly. Basically it will cure most of it, but then a thin layer remains un-cured at the surface. That's a problem since the nice surface finish is exactly what I'm seeking by using Norland...

I guess I'll have to try another lamp and hope it has the proper wavelengh.

If anyone know if the UV lamp I've posted would work?

thanks!!
 
Alex,
You have to order the Nichia UV LED (#NCSU033A) directly from Nichia (they probably have a sales representative in France). I did without a problem - it's pricey, but effective. :thumbsup:

May I ask you how much you paid for it? I've been browsing Nichia's website but I can't find any contact in France. I've sent an inquiry though, we'll see but I'm worried about the price.

I suppose I could give a try to the UV pen I've linked above but if it's not powerfull enough to cure Norland it'll be $60 waited.
 
Alex-
$125 :eek:oo:

EDIT: If it helps, I dealt with Heather Irvin at Nicha US - you could try dropping her an email. heather(DOT)irvin(AT)nichia(DOT)com

I left my vial/piston on my window sill and left it there for two days.
It was not in direct sunlight .... I guess it just takes a little longer without direct sunlight
 
Price per LED for the Nichia UV drops considerably, if you purchase 5 or more...Maybe gets some peeps together for a 'group purchase'
