So tonight I was fooling around and decided to build a light. I poked around my parts box and dug out a DB-1000, a TWAK Lux III, UCL, a HOTLIPS "C" and a Mag 3 "C" body.
I was inspired by a couple of CPF'ers to make a glowing disk around the emmitter. That took a couple of hours but I am quite pleased with the result. I wired up the mag and the DB-1000 and the emmitter to make sure it works. I then put it all together.

I would have built the light around a 5 watt star but I destroyed it. (bummer)
My first attempt at the glowing ring looked like this.

As you can see there is much improvment.
All in all this is a very nice mod. I should get some good runtime with the DB-1000 running the show.
I like the 3"C" body because it will give me the same light as the 3"D" and a much reduced size. I hope I did the right thing by potting the DB-1000 in the HOTLIPS with epoxy.
Any thoughts?

WOW

looks nice, Mofo! /ubbthreads/images/graemlins/thumbsup.gif
what battery are you using?
and the glowdisk, yea looks so much better than your first attempt. I love the idea. all credit to the first invented it /ubbthreads/images/graemlins/grin.gif
 
Whoa, as Elvis would say, "Thass noss, thass ver' noss indeed."

You could also try painting the area you want to glow with clear nail polish first then gently sprinkle glow dust directly on it, blowing the rest off when dry. Real easy to get the exact pattern and coverage you need that way, just a thought...

Now we want beamshots!
 
yaesumofo,
Have you been measure the current drawing out from 3xC?
I had made my FT-3C to DB1000 before. But it seem the batt cant feed enough power to the Lux3. My lux3 Vf is 3.77. And assume 70% efficiency, it require 1.2A from alkanine 3C batt. And about 1.4A when the batt voltage drop to 4V.
I read 0.7A from 3C
0.99A from 4C
0.81A from 5C
0.67Z from 6C
 
Nice! /ubbthreads/images/graemlins/thumbsup.gif

Yes we need beamshots, or better yet, "action" shots.
 
Very /ubbthreads/images/graemlins/cool.gif, yaesumofo! /ubbthreads/images/graemlins/thumbsup.gif

Your first attempt at the glow ring looks like what my final attempt would look like after I ground off all the strings of glowing epoxy that connected it to my nose, eyeglasses, fingers, the reflector, body, work bench, and, of course, the emitter dome itself. /ubbthreads/images/graemlins/icon15.gif /ubbthreads/images/graemlins/yellowlaugh.gif

Now you tell me.
I will take beam shots tonight for all of your viewing pleasure.
The Glopowder/epoxy thing is a bit of a pain. But is is cool. Blue next. I wish that the pedestal on the hot lips was a little taller. Then I could put a PMR in there and the focus would work. I also wish I had not destroyed a 5 watt star in the process. Ho do you get those emitters off the star with out breaking them? Thanks for the compliments guys. As the flashlight freak that I am it is nice to get validated. Pictures tonight.

There is a fix for the PMR/MagC/Hotlips issue where it does not focus tight. As advised by Paul, a section of inside the head must be machined allowing the head to screw down farther.

For removing emitters from stars, look here. Make sure you skip step 2 and making the bend parallel to the emitter's leads works better than where the bend was made in the pics.

There is yet another recipe for applying glowpowder. I get the best results using slow curing epoxy over the other two methods. Painting the surface white also gives a better glow IMO. With blue, make sure you mix in enough GP otherwise it won't glow very bright or long. Of course it still won't glow as good as green though.

I've tried this method also but I don't use it & personally I like the epoxy method best. I still think the epoxy way works best. I forget who posted this but here it is:

Firstly, helpful materials:
1. a 1/2 oz. bottle of lacquer-based CLEAR fingernail finish.
2. a 1/4 oz. bottle of clean unleaded paint thinner.
3. small bottle of "white out" -like typewriter "correction" fluid -to be used as a base (primer) coat.
4. 3-4" stirring stick (not plastic)
5. a 1/4 teaspoon plastic kitchen measuring spoon
6. cheap medicine dropper (for thinner)
7. piece of folded cardboard or small piece of paper for small funnel.
8. clean, empty, sealable small bottle 1/2 oz. or larger.

EZ recipe for a DAZZLING paint after-glow result:

A. pour out 3/4 (75%) of the 1/2 oz. fingernail fingernail finish into the other little empty bottle and cap it tight, so it doesn't evaporate.
B. carefully fill the plastic measuring 1/4 teaspoon of the glow mix to a little more than the level mark, and gently pour it into the fingernail liquid. FYI-that 1/4 teaspoon of pigment weighs about 2.25 gm.
C. stir the powder into the liquid thoroughly.!
D. Screw the cap (with built-in applicator brush) tightly down to prevent the mix from drying out.
-There..., now you've mixed some great paint!

I suggest keeping that little bottle of paint in motion every minute or so to prevent the pigment from settling,-and you having to re-stir.

Simple and quick application:

A. on a clean, dry surface, quickly paint a base coat of the "white out" (or other oil-based flat White paint).
B. After it dries (2-3 min)., apply a thin coat of your newly mixed Glow paint-and as soon as you have applied it, put the cap back on Quickly -to minimize evaporation. It's a very good idea to keep that bottle of new Glow-paint moving in your hand a little -to keep it well mixed.
C. All you need to do then is to apply 3-4 more thin coats (letting each one dry thoroughly -usually 5-10 minutes under average conditions, and a properly dried surface will look FLAT, not shiny), and if you're in a hurry you can use a squeeze air-bulb or even a small fan to speed the drying process.
Tip: if the paint mixture does become too thick, making it hard to apply evenly, just add 3-5 drops of the paint thinner with the dropper to thin it out very nicely....-not too much!
-And stir it in well before re-applying.
FYI-if you've stuck with my recommendations as far as proportions, you have a pigment to base liquid ratio of 30-35% by weight.

Don't do the following!:--------
1. dilute with lacquer thinner or acetone-you'll wreck the mix.
2. don't add bird or buckshot into the mix to facilitate mixing-the lead will leach into the mix!

You can do the above procedure from start to completion in an hour or so, -with decent ventilation for each coat to dry, but don't expect the painted surface to glow brightly, until the paint is dry.-that's how it works folks

When drying is complete, using the blue/green pigment, you will have a glow surface that is 4-5 times as bright and lasts 2-3 times longer than the green glow sheeting, and is 40% brighter (IMO) than Alien Skin -especially after 2 hours in darkness.

A final touch:------------------
The painted surface can easily be given a thin coat of protective clear lacquer from that second little bottle that was left over.

General Info:-------------------
The Regular green pigment glows brightly for about 8-10 hours and only need 30 seconds exposure to strong light to charge up.

The more powerful blue/green paint glows very well for 16-24 hours and requires at LEAST a full minute to properly charge, -and by strong light I mean the surface should be held 3-4" under a cool white fluorescent if possible......

The glowing surfaces will have a lifespan rivaling that of the LED, I would guess. Hoop-de-doo!
The entire procedure described above takes less time to do than the time it took to write this little article -about 70min.

p.s.-short exposure to UV light on a 2" x 3½" painted business card gave enough light storage to allow me to find my way around a house full of dark rooms for about 40 minutes, and to easily read average sized printed copy in a TV Guide for almost half an hour....

Edit-4/5/02:
One really good way to tell if you've mixed your new paint in the proper proportion is to stir the paint thoroughly and then set the jar down on a flat surface in a dark area for 2-3 hours.

Then, holding the bottle level under a strong light to charge up the mixture, note the level of the settled pigment at the bottom compared to the total fluid level. It should be no more than about 1/3 of the whole liquid.
*Edit-4/5-a last final way to tell if you've got the right mix ratio is that the Dried painted surface should feel very slightly gritty-like emery paper.

Also, the mixed paint should flow a little,-if it doesn't, then just add 2-3 drops (+) of the thinner. -If it's too "gooey", it won't go on smooothly and give you a nice Even coat..

Edit-4/20/02:
To test to see if you have picked the best base liquid to use, it would be great if you could hold a small swatch of just the Clear base painted on a White business card under a blacklight. If you see little or no discoloration, you've got a good one! I tried 5 or 6 different brands under a black light and 4 of them looked a little "blackish" under that light. It WILL make a difference in ultimate brightness.

Addition-5/14/02
It's also best to try to mix up just a little more paint than you will need for the particular job you're doing. Over time, the lacquer medium will darken the pigment a little. So the absolute best possible results come from a fresh mixture. However, the finished painted surface will
not deteriorate over a period of time-especially if it's lightly lacquered.

I am not sure how to do this measurement. The voltage at the emitter is 3.52 volts.

This shot is The DB-1000 on the left and a 6 volt direct drive on the right. Same reflector and UCL.
The direct drive is a little brighter.
I will say this both of theese lights light up trees with a beautiful spot at about 200 feet.
I will try to capture this tonight.

Any reason why you can't just buy glow paint to begin with? Of course I don't know where you can get the "good stuff" in pain t form (i.e. the strontium aluminate).

I'm actually debating right now if I should get glow paint or powder. Paint seems like the painless way out...
 
You can get premixed and ready to use glow paint from www.readysetglo.com. It has been my experience that they sell the highest quality glow powder around, also the pigment in their paint will not settle over time. I have not yet purchased any of their paint before but it sounds like pretty good stuff.
