What's the best UV light for Norland, and how long a shelf life does Norland have?

I just used some Norland I got quite a while back and it apparently is just as good as ever, even though dated to expire April 2009.

It took a long time to cure however and I'm thinking of getting a UV light for both fun and to use in conjunction with Norland for curing purposes.

Please share any views you have on UV lights in general, and especially related to their effectiveness at curing Norland, which ones are better/worse and if you've ever had problems with Norland due to aging.

One light that at least somewhat appeals to me would be an Arc-UV, but I'm open.
 
I've got an Inova UV light - cures my Norland that is also dated 2009 in under 30 minutes. Bought the light cheap - but haven't seen one for sale since (haven't been looking though).

Norland is supposed to be good past exp date if you keep it in dark & cool place.
 
Thanks for the tips guys! I started a WTB thread in the Marketplace to try and beat the bushes for any unused UV lights laying around.

Tried using my Quark RGB on the chance that there was some UV in it's blue, which lights white items up fairly well in black light fashion, but nothing. Disappointed, but at least I know now...

nfetterly - won't the sun cure it in 30 minutes? I am very interested in this - just ordered a Photonfanatic DLC Double groove - it's got 5 trit holders milled at the base - plus I want to put one on a ti BitZ and 2 on my Spy 007. Looking to hopefully take the 'inexpensive route' to get this done.

Has anyone tried this one? It looks like it is designed to cure various epoxies, but it is HUGE!
Of course, this light engine is an option (since I have quite a few McGizmo hosts it could 'ride' in :eek:), but it's a bit more $$ than my budget is capable right now, after the acquisition 'tear' I've been on lately...:crazy:

So will any of these 'better' lights cure the epoxy faster? Or is the sun still a viable option? Although with 5 trits in a circle, it could be a long project.

Trying to learn - incidentally, I ordered a 1 ounce bottle of Norland 61 from Edmunds Optics - if anyone has a vial they'd like for me to fill, I'd be happy to help out a CPF brother/sister...until it runs out. You can PM me. I should have it one day next week.

Thanks!

Hahahah - well I look a little foolish. My Inova looks just like the one in the link - I have a lanyard through the top & I just hang it over the Norland & trit and then walk away for a while. Gets the job done!

Yeah that double groove looks pretty wild - I've been sorely tempted, the trit slots and DLC are what is pushing me over the edge.

Good to know it cures that fast - I've got (eventually) some tails coming from Moddoo that take 3 of the 2 mm x 8 mm trits, could be a little challangeing to get them set nicely.

Thanks, Norm. I did read that on their site...thanks for the 'real world' confirmation!

I struggled with that DLC double groove from the day he launched it. The 5 trits are finally what got me - this will be my first attempt at setting trits so I bought a 1 ounce bottle of Norland 61 and a 'good supply' of trits from B@rt. First attempt will be on the BitZ - then "gulp" my 'new' (to me) Spy 007 - then I'll go for the 5 trits on the DG DLC. Sunlight is great, but with 5 trits it'll be a process - set one, let it cure, then move to the next. I'd hoped that a good UV light might make it a bit easier - still considering a Nailbender drop in or one of Don's Nichia engines - but I'd rather save that $$ if I could!!

And NO, you DON'T look foolish!!! :twothumbs If anyone does, I do, because the Norland site clearly explains things, but I wanted to hear a real world report.

Thanks, Neale!! :twothumbs
 
Hi Mate
That one is using probably 3mm LEDs.
The single LED one i'm using would probably be more powerful and last longer
(as in LED lifespan), unless they're overdriving the LEDs

Cheers

Thanks Dom - looks like a cost effective route. I think I'll take your suggestion. One question: how long does it take the Norland to cure with this light?

Thanks!!

Hi all,

I just received a nailbender UV dropin and will be doing some setting in the next few days so I will report back with how it went.

Cheers pugga
 
Nailbender does a nichia 365nm d26 drop-in for $125 i think. The chip itself costs $100 from nichia...

I think it's same chip as mcgizmo uses...

I was told it cures is very fast, like 5 min or so...

I've had one of these for awhile -works great on Norland (at room temp)
I've had a container of Norland 61 in the fridge for 6 months or more -used it the
other day for fixing a loose diamond in a ring.

Cheers

I received trits, Norland and the light Dom references in this post. Yesterday I did 'test trits' on my ti BitZ and Arc 6 - worked flawlessly. Dropped the trit(s) in the slot, applied a couple of drops of the Norland with a toothpick. Attached the UV penlight to a mic stand/boom I have, and positioned it over the trits about 2 inches away. Walked off and left it for 5-6 minutes...the Norland was cured and the trit is sitting securely in a tiny little vault of cured Norland 61.

I know, pricey - the cost of the Norland and the UV light, but there are other uses for this stuff, and now I am confident to put 5 trits in a DLC coated Photonfanatic double grooved light, and 2 in my Spy 007!

thanks again, Dom

Holy moly that UV penlight is expensive. Glad it worked though! I'm too chicken to mount my own trits. :p

You know - you are right, the light is pricey!! It's a toy! Of course, it does 'show' things that are not pleasant (a puppy or kitty's 'leavings' should they have an accident), and other things that are not unpleasant. And someone mentioned resetting a stone in their wife's ring...

Oh, well, I know, I can't rationalize this!!:eek:

But as for putting in the trits, it is NO BIG DEAL!! The trits just drop into the slot, then you put a VERY small amount of the Norland in the slot. Take your toothpick and center the trit, and if you have a light, begin the presetting then curing process. Or you can put it in the sun for an hour or so and get the same result.

That's it! I'll photo chronicle the installations in the Spy and the DLC lights this weekend. :)
