Want to buy/Split some Glow Sheet or Powder

Ok so we got some people interested now lets go for a color. I put my vote on NP-2820 (glow color is blue/green). You can find the colors and the power types on the following page: http://www.nichia.co.jp/glow-e.htm
Another fourm member emailed me (a US one) stating that he could help avoid the duty/taxes bit by getting it in the US then forwarding it to the Canadian parties also interested - this would be much help (and cheaper!) My question is how should payment be arranged? Personally I am thining of going for like 20g+ of the stuff but no where near 100g!
 
I've just been advised by Nichia that the best glow-powder option is "blue/green". How about that??

I'd be in for 10gm-blu/green.
Btw-just in case I would wind up being the "mail-assist"-if decided, I will include some 5"x7" green as well as blue stick-on glow sheeting for you-n/c

. Just a thought..

p.s.-have a .1gm.(1/10th) digital scale to weigh it with too.
 
vcal. O.K. by me if you want to be the "mail-assist". I would be glad to but no scales at my place.

vcal,
thanks muchly for taking it on. (phred is pretty disreputable !!)
From my "Green Laser Group Buy" experience, I strongly suggest you get some committed buyers before doing much admin work.

Q. Would your glow-paint idea definitely be OK with this stuff, as in
Topic: Long Lasting Luminosity
@ http://www.candlepowerforums.com/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=3&t=001362&p=1

On colours, my first choice would be

NP-2810, Body Color White, Afterglow Color Purplish-Blue,

NP-2820, Body Color Yellowish-White, Afterglow Color Blue-Green.

as my second choice. phred, the NP-2810 would probably be more Indiglo coloured.

A few grams of each would be enough for my messing around.
If I go for around USA $25, do we got enough interest to make a buy of both choices ?

vcal - that is very nice of you!
Ok so it seems blue/green (NP-2820) is the domanant request right now. (yay)

Out of the 100g sample we have:
vcal - 10g
phred - 20g
PhilAlex - 20g
me orby - 20g

And vcal seems to be the best choice for being our mailer.

That leaves 30g to split between the remaining members that may want in...

LEDagent, something ridiculous, "MY": Could you please state the amounts you would like? (10g a piece would round this up quite well)

And there is still an issue of how we are going to pool the money to pay for this.

I would say lets try to keep all thinking in this thread as it wil be easyer to keep everyone upto date.
 
Has anyone directly compared the Nichia product with the Extremeglow product? There is a big difference between $100.00 for 100g and $15.00 for 75g. Is the Nichia really that much better?
 
I'm sure the Nichia product is better, but I don't want to spend a large multiple of what I would have to get something that isn't a multiple of brightness.

I'd PREFER the Blue glow stuff, btw. But I'm easy, either way.

There are some other people who were sorta interested... MY and SOMETHING RIDICULOUS... You guys wanna chime in?

If my fellow forumites can wait just a few days....I intend to do just that comparison!
-After all, guys-we're talking about a FOUR times price differential-how about it?

p.s.-I do have some of that X-Glow blue/green mix left that I've been bragging about, and I'd like to see ANYTHING that claims to be even better. ...

-that, I gotta see

Thing is, I'm a little glowpowder-shy after buying the Extremeglow product (green).

For me, waiting a few days to find out which product is better is well worth the $$ saved.

The Extremeglow product I received works, but I'm somewhat disappointed ... it is technically still glowing after 10-12 hours after a full charge, but to see it I have to be in absolute dark with dark-adapted eyes. ANY extraneous light obliterates the glow.

However, if Nichia's product is MUCH better than Extremeglow's, I'll be interested in 10g. That'll make a nice batch of paint.

vcal - I'll be watching for your comparision. My participation in a group order will depend entirely on your observations (no pressure ... really).

I'd love 10g of the Nichia powder (if it really exceeds the cheaper stuff by a significant margin), and if there's still a glow sheet deal going down, I'd like a piece of that as well (one or two feet should do).

Thanks!

Was that the sheeting or the paint mix that you used? Also, even though the blue/green (mix) that I used for 8 months is about 30% better than the straight "green" mx, and about 60-70% better than the sheeting, it should be remembered that non-radioactive products like this do have their limitations...
IMO-the best of them I have experimented with over the last year are best appreciated/used in dark areas, and dark-adapted eyes. -That said, when the materials are properly charged up, the effect is very useful, and 15-20X as strong as the old zinc-sulphide kid stuff-glowing like Fire-for several minutes at least...

The biggest drawback with products like this is that for really superior results, it requires effort (ya really gotta mix yer own paint
frown.gif
)
1. good grade pigment
2. right mix ratios (30-40%)
3. highly reflective base coat
4. 3-4 thin coats(glo-mix
5. practice (and patience) -and I was really lousy at it when I first tried it...

Lastly-these products should not be terribly expensive. -The people at extremeglow promised me 75 grams of the best mix they had, and the actually sent me 86 gm.for $22.(!), and it turned out to be really terrific stuff to use--once I got the hang of it...
-A lot fun to fool around with-especially when you have white LEDs and UV or even just black light to charge 'em up with

vcal - Do you have some of your own Nichia powder comming?
How are you going to compare them?
I seem to be a bit confused right now...

NP-2820 Blue Green-the BEST
<HR></BLOCKQUOTE>
Yes

Very simply-I seal up the samples in tiny Ziploc bags charge them, and put them in a totally dark place for 12 to 24 hours. At that time (in darkened area-eyes dark adjusted)they are simply compared side-by-side for remaining brightness.

btw-I have tried other colors like red, yellow, and white etc.
–the purple was the prettiest, but I found all of these colors to be very disappointing in brightness and longevity.
 
Darn if I'm not getting a kick out of this thread. I'm still in. If folks want to wait for Doug's testing thats O.K. by me. (hurry, hurry). As far as Sir LightLover is concerned, just send him any colour, he'll never know the difference. He is a Londonite ya know.

Paint. Reflective background (ScotchLite white), 5 thin coats of 'paint' (powder constantly stirred in a clear polyurethane base - not water-based, about a 50% initial mix but with instant settling the stuff being applied is closer to 40%), fully charged for 30 minutes placed 8 inches below a halogen lamp.

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>it should be remembered that non-radioactive products like this do have their limitations...<HR></BLOCKQUOTE>

Yep ... this stuff sure isn't a tritium-excited phosphor (too bad)! My disappointment is derived from previous postings I've read over the past year that praise the product's brightness (I'm not laying blame here). I was hoping this technology had improved much more than it has. The powder I have IS worthwhile and it IS better than the old technology ... it just doesn't live up to MY expectations.

FWIW, Extremeglow does not misrepresent the product (nor, IMO, have you) and they filled my order quickly and completely. No complaints on fullfilment at all. I do want to share the opinion that the technology from my perspective still has room for improvement. Maybe Nichia's product is more in line with my expectations? Hopefully, that's what you'll find out for us.

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>about 30% better than the straight "green" mix...<HR></BLOCKQUOTE>

Just curious ... does that mean the blue/green mix is 30% brighter, lasts 30% longer, or both? Or, is it 30% better for other reasons, and if so, what are they?

- - - - - - -

The good side of my purchase is I now have lots of green glow powder to play with and I get to find creative uses for it (and maybe to answer the question of just how much stuff I really want glowing at night). Too, I now have a basis of comparision on these products.

It may not be do-able, but when you do the comparision test between Nichia and the Extremeglow products (both will be the blue/green, I hope), could you note brightness levels at a few different times? For example, brightness comparisons after exposure at 10 minutes, 1 hour, 4 hours, 8 hours, 16 hours, etc. until exhausted? With your experience, you probably know better duration points to measure than I've suggested.

I know it's a lot to ask that you do time-dependent sequential observations, and you might not be able to do it at all because of your schedule, but that'd be good information to have. At the same time, I'm confident we'll all be happy with anything you can tell us after comparing them!

Thanks, in advance, for offering to do the testing. As the glow-stuff guru around here, have you considered setting up a web page with glow product comparisions?

mark-major equip. failure here

off-line 4 a few days......
ans. 2 your Q: bl/grn. lasts 30-40% longer than reg. green.

yes(

)-2 Best Nichia samples coming...side-by-side tests (4 different pigments compared), & your suggestions are noted.

back in a few days.. -30-
 
I don't know why I didn't notice this thread earlier!

I'd be very interested in some glow sheeting from Extremeglow. I'll take the 3 feet that PhilAlex doesn't need, or split it further if some other Canucks want in.
