Yikes - Jetbeam PA-40 actually - Not very budget , but was made an offer I could not refuse [ dont ask - cant tell ]

Glad you're working out the details for me because I wasn't thinking it'd need a shorter reflector. Before/after beamshots would be great;)
I'm interested in lens dimensions too. I can see myself camping w/ one of these in each back pocket - one floody, the other w/ http://www.dealextreme.com/p/50mm-18mm-2-80-degree-glass-optics-12834
edit:i suspect the emitter would be closer than focal length:(
Good luck, I want to see how this turns out!
Another model being still a budget more or less is the Ultrafire C88 you can find it in ebay for US$39.99.
Here's a few links that I have found interesting and helpful on DC projects.
How to use a meter for flashlight measurements
Serial (Series) battery circuits
Serial/Parallel battery circuit (towards the bottom of the page). I like these circuits for using AA batteries in 4D-6D Mag-lites, as you get more voltage and more amperage by making a series/parallel battery pack.
Engineering Toolbox Thermal Conductivity of metals - This site has lots of great info
Electrical Conductivity of Metals
DC rule of thumb (I feel it's true from my own testing, but many disagree totally)
How to find the center of a circle (like a heat sink that you are putting an emitter on)
After all, I just can't sit and wait for 14 more days, so I look for info, parts, etc. Passes the time...
Those are some nice to know links you just shared. Thank you :-)

The problem with modding the c-88 is lots of people like it .. just like it is .
the Saik being 1/2 the price may be twice as hard to mod ... but who says that's not fun too.
First thing i'd do is fill that dang hole with copper ..I have a cheap old light I just pressed a pill into a hollow pill like that ...I had a pill that looked like it would fit .....I made it fit :)
Watching with interest! Old Lumens-a man after my own heart! No rich guy stuff here either. All hand tools, some of them pretty rickety. But the rewards are great!
You're gonna love this! It's a new pride & joy specifically designed for good color rendering in outdoor use: [image] The Neutralizer. [image] The more and more I play with neutral tints, the better I like them. Much easier on the eyes and more pleasant to go on night walks with the dogs. The specs: Mag 4C host, PTS-2 heatsink, AMC 8X 7135 drivers X3 with extra stacked 7135's to make each XML 3.5A on max. Modded original Mag switch so there isn't any mode skipping. 3X high CRI XPG's (3000K)…

Checked out your link. Great Mod! Went to CPF too and read the thread there. Good info if I ever do multiple emitters. 7 of them in a 4" head... Someday maybe.
Just in case everyone was wondering, I found that the DX package came into the US today, so hopefully it will get here after Thanksgiving. Maybe around next Monday (I Hope)...
From some measurements that Essexman gave me on his SAiK, I think there will be a Lot of Modification, since the stock lens and reflector are not anywhere near the dimensions of some of the replacement stuff available. It ought to be interesting if it can even be done. Unfortunately I may have to go looking for a different reflector. The lens will end up being a UV filter from a camera.
I love this chuncky light.
I put a red phlatlight emitter in one of these a couple of months ago. Just DD off of the three aa batts. So never had a heat issue with the plastic reflector.
Cant wait to see how yours turns out.
I have this Saik but built it into a 2W 445nm laser with a 26650.
Hello this is my interpretation from the SAIK SA-305. 3 Cree XML U2 driven with 3 x 2,8 Amp,
1 Battery 32650 3,7V 5000mAh!
Congratulations! Welcome to BLF.
Don't take this wrong, but....
It might have been more appropriate to have started your own thread to show your build instead of Hijacking this one...
But...
Probably I'm just too sensitive.
But this is a thread about the Saik Sa 305
My apologies for speaking out of turn.
Sorry for the possible threadjack but am I the only one who see's bad things in those pics of daysoft's?
Sorry my english is not the best, May be i start an new thread. Do you think it´s better?
interesting that you'd choose a UV filter for the lens - that just happens to be on hand? or happens to fit? I'm sure you'll share component sources when finished...just curious.
do you have a role in mind for the finished product (ie throw, flood)?
It is more floody, but incredible bright. The UV filter was the only chance to fit,
i don´t found anything with this diameter, so i take this from my old camera. Perfect!
It takes at the tailcap about 7,8 Amp on high! ( 3 Mode low-mid-high )
