Phlatlight 12w red LED flashlight!

Typo. I meant LM138.
Anyways, with 317 I think they can be paralled..

Yes, it is possible. :)
There will be some practical problems with machining metal for heatsinking and getting enough Amp's out of the batteries.

You have given me ideas for boosting the output of one of my flashlights. :)

by any chances did you mean

?
:P

edit:
oh and you really writed 'silicon' ? :O


@Toke
:D
Machining metal for portable heatsink should be a problem, agreed, but a flashlight with 2.5W red output will surely be big.. imo

After seeing this I thought I would get mine out and check it out, I haven't done anything with it since I took it out of the projector and all I can say is HOLY SH*T is that thing bright. Even at the 1.2A my power supply was putting out that thing is blinding. I have a Raidfire host from LarryDFW that I was going to put a 445 in but I may change that and see if I can get this guy into it.
 
LarryDFW,
Thanks for the link, that gives me a possible project to start on in the near future.

What about using forced air cooling?

I wonder if you could make a heatsink out of low melt (95C) BiSnPb alloy...
Then blast air down the stack to keep it cool, if it works for a laptop CPU it ought to work fine for this.
Or salvage a used heat pipe from an old notebook, Apple Macbooks are nice for this as the "stack" is fairly small indeed.

I really like the square shape of the beam :D
just got a pt-54 from a projector, I really want to try a similar build as yours.
 
No need to buy a separate lens for this host. The lens in the Phatlight works just fine.
 
Sorry 'bout that. I was trying to post a picture from my hard drive and everything seems to want a URL. Any suggestions?
 
Try attaching a file to your message, and then using the link it provides to inline it in your message.
 
What's so dangerous about this led light bulb?? :confused:
Can someone explain? I'm new to all this.

I would be grateful if you would direct me to the instructions for how to attach a file to my message and where to find the link it provides to "inline it..." into my message.

If this request is too basic and you feel it a waste of your time please direct to to where I can rtfd. I have never used this type of system before.
 
I don't think there's anything particularly dangerous about this LED. It's just pretty damn bright if you give it enough juice and as I'm sure you know, if you stare at the sun for a period of time, it's not going to be good for your eyes. Also, if you pump up the amps it's going to get hot and you might burn your fingers. A laser diode is a much more concentrated beam of light and does present some very real dangers. An LED spreads its light out.
 
Thank you so much for you very instructive reply. I had not guessed this software would require such a convoluted means of doing something as simple as inserting a picture. There must be complexities of which I am not aware. Thank you for your help. I was much vexed after after spending a great deal of time searching this site and and finally requesting information from whomever ignores the "contact us" address.

Hopefully, the photo I wanted to share will now appear below.

The LED is a point source emitter, meaning it put out light from a very small point (in this case a WHOLE LOT). That means that the eye will also collect the light on just one small, concentrated spot on the retina, resulting in a high risk of eye damage. So DO respect this LED as you would with a laser, even if the LED was only rated 1W input power.
