What duty cycle limit are you using now that its 170mW?
I'm wanting a tiny 10440 build now. Heatsinking mass will suck I know but I love tiny builds, just can't help it. One of these days I need to ram a microcontroller IC into a build to have temp & runtime monitoring.
It's still good to ~45 seconds. I can "feel" the warmth with my fingers at that point. Then I let it cool down
Hey Dave, Thats a great little build. Its nice to see one of these ran at a lower power. If/when I ever get a 445nm I plan to run it at a nice low current. I want 150-200mW max. I just do not like the idea of having one of these running at 700mW+ its just to much for me. Id burn stuff.....like curtans....couch...the cat......
Keep up the great work!
It is very pretty at 170mW. I have my Kryton set at 700, but quite frankly, it is too bright to "use" anywhere but outdoors (and there are very few places here that I can use a laser outdoors )
Nice build Dave!
I''ll bet that 2 X Energizer e2 lithium primaries will give the same output as the 10440...
They tend to give a little more voltage than alkalines, with plenty of current available. You will be at about 3.5 volts.
Plus, they will have more capacity even in parallel, than a single 10440.
But still yet, a rechargeable is a good option... :gj:
The only lithiums I had on hand here were "used." I'll pick some more up and run a comparison.
Daguin, what module are you using?
I've found that the "Sure" modules offer better heat transmission to the host in pen style builds than the Aixiz.
The diameter is slightly larger and allows for a better press fit into pens.
In most pen hosts I've tried, the Aixiz modules slip right out the back end.
Of course, the disadvantage of the Sure modules is that they are not threaded all the way down so cannot be used with the high power lenses unless some threading on the lens nut is removed (I'm sure you are aware). But if you are using Aixiz glass or acrylic I guess it wouldn't matter.
This one is an AixiZ. When I use them in these pen hosts, I rough them up and add some solder to the module to "tighten" them up. There is so little metal in these pen hosts that I don't even consider them part of a sink. If it starts to feel warm, that is my limit for them.
