500 Lumen - AAA Flashlight (photos) - Work In Progress

[Bigmac_79]

over-discharge protection is definitely in the core spec for this light.
Im still checking if/how we can implement it and still support 1.2/1.5V.

Current spec plan is:
Over Discharge Protection (auto switch off or flashing, when voltage output is between 1.8V & 2.8V (this is to prevent unprotected Li-Ion from over discharge)

I'm glad to hear that! Cutting off in that range sounds like a pretty good bet if you can make it happen.

I like that porsche analogy. If you can pull this off I'm in for one to.

Thanks

Hi, been away for a while subscribed to this thread.

I like AAA lights and @ 65.00 if this is produced am interested in @ least 1 light.

Thanks and good luck

Hi Everyone,

I've put up a very simple page, where you can subscribe if you want to receive an email when the Torpedo is close to completion.

I will keep updating this thread, but in case you dont want to miss the first run, this will make it far easier for me to manage when the time comes, than looking through the posts to see who wanted to be notified.

It just a keep me updated list, no obligations or commitments required.

Thank you and as always feedback is most welcome.

Not much there yet...
but gotta start somewhere.

Thanks Acid87.
The list will help me plan demand so that on the first run I can aim to accomodate at least everybody that wants one (or two, or...)

Had to be on the list too...

Ya outta make it so ya get the sonar ping sound once the page loads up. Or some memorable line from The Hunt for the Red October, Sean Connery of course.

There's a dive watch company that does that, or did at one time. BUt check this one out: http://www.zixenwatch.com/

That is an awesome animation!

Thank you.

I suggest using aspheric lens rather than parabolic reflector
-Thicker aspheric lens = less dist. between led and lens due to a larger diffraction index
=> More space for heatsink
=> Loss of light flux is less
=> More throw

I have read that with an Aspheric lens, up to 50% of overall output can be lost depending on the diameter of the Aspheric lens.

You may be confusing an Aspheric lens with a TIR optic.
They are not the same thing.

[jorn]

Yep, the xml throws the light in a ~130 degree angle. Put a tiny asperic in front of it, and you will loose lots of lumens. Prob more than 50% in this small scale.

[Acid87]

Keep it simple. Don't try and make it a dedicated thrower then it's more desirable to all types of folk.

I agree, this is a keychain light...I would prefer a basic LOP type reflector.

Looking forward to picking up two of these!

[hazna]

I'm really intrigued by this concept light, I've subscribe to mailing list and if the price remains ~$65 or under, I'll commit to one.

I guess the main barrier to overcome would be the heat generated. Any idea on what the dimensions for this light? Is it going to be a lot larger than AAA lights? I'm also a bit concerned about the reliability of 'loosen to turn' on lights, especially if you going to have 4 modes. I hope you do significant R&D to perfect the UI.

I like what you've done with that itp! Is it difficult to operate one-handed, with such a small body segment?

Thanks for the suggestion.

As mentioned by easilyled & jorn
an aspheric is probably not the best fit for the XM-L in this small a package,
though I realize we all have our own individual preferences.

In this small a package, an emitter like the XP-G/E may be the better choice with an aspheric,
but for now, as it seems most people prefer flood to throw at this size,
I will go with a reflector in version 1, unless by some miracle,
the perfect TIR lens shows up in the next few weeks.

Agreed. A great general purpose light at this size.

Thanks for the feedback.

For everyone's convenience, I had added target dimensions to the first post recently...
with AAA Body = 65mm Long, 14mm diameter
with 10280 Body = 47.5mm Long, 14mm diameter

I may add some more info to that first post as things progress and if warranted.

>concerned about the reliability of 'loosen to turn' on lights
there are a few possible ways to do it with the modes.
both reliability and ease of use are of high importance and I will update more on the details when available.

>I like what you've done with that itp!
Thanks
Usually if I hold it in the syringe grip, I can get momentary with just one hand, by pushing firmly on the tail end.
twisting is usually a 2 handed affair as there is not very much to hold on to, but for the size (or lack of) it stays fairly un-noticeable on my keychain.
