Mits 500 mixup

Seems I was wrong about my drivers, they are 750ma drivers, getting 800 ma from one

Wow I just put a fully charged IMR 18350 in my 1.4a flex mitts build and I got 1.3 peak! :beer:

try the AMC 7135 driver 1.4a 5 mode or 3 mode they work nice with the mitts!

Hi Billy,
I'm definately gonna go full power with my mitsu 500, I'm really liking it! Even at 800ma's it's a beast. Gonna order a driver today or tomorrow

Hi VV,
Reading this got me going i have a Mitsu in the diode box for a long time now . Time to throw it in the PSU and see what mine will do safely. I'll put it into a pen build nice compact little burner. Maybe mine can achieve 1W or more keeping my fingers crossed. Thanks guys for planting the seed lol!!

Rich

Loving mine,
Trying to combine 2 drivers for 1200ma's, hope I don't kill it....lol. it was a beast at 800ma's so im hoping this will work

HiVV,
1.2A's will get you a better 1W out put, i'm going to PSU mine first to see where it starts to roll back first. This way i'm not guessing when i set the driver current and kill it. This way i will know if my diode can do 1W or better .

Rich

I had mine on the psu yesterday and I went to 1.2 amps no problem, was still getting brighter

Hi Rich,
IT WORKED!!...lol. Don't have to wait on a driver, just have to get it all in a host.

If I ever get another one, I won't go over 400 ma. I'm gonna order 10 lpc826's, I like them alot better. They seem to be just as bright

The last lpc826 I had ran at 550 ma's no problem

They may seem as bright, but without an accurate LPM reading you're just guessing. If you plan on staying in this hobby, I'd seriously consider getting one.

Hi Paul,
Your right about me guessing, that was just my opinion on brightness, not power. I want an lpm tho and agree with you that I need one and plan to get one soon. I don't think I'll bother with the lpc840 anymore when the lpc826 is out there and able to take more current while not as fragile

That's part of my point. If you have an LPC-826 that is still taking 550 mA, I'd love to see it. My experience with all the LPCs is that they can't take that much current and survive. If you have ten LPC-826s I'd love to see what you can push them to without a premature failure. You can't go by what just one diode has done. It takes several before you know the limits of that diode.

The one I had doing 550ma's did 600ma's on the psu. I killed it on the psu trying to get 700ma's out of it. PMan has posted that he sets his at 550ma's also. They seem to be capable of more current than the 840 from my little experience. I may not give up on the 840, May have been something I did that killed it. (Other than over driving it)

Edit:
I'm curious as to how yours does, did you get a replacement?

They will take more than 550mA. I've run them into the 670mA mark and hit just over 400mW on many of them. Not sure why you are having issues other than drivers being finicky things. The reason I run them at 550mA now is I discovered that you can use a driver taken off a fasttech 532nm module and set to max on the pot that's around what the output will be. I think that is an older graph. I just think that maybe they are built slightly better now or something.
The driver I was using to take them to 400mW was those standard AixiZ ones where I set the pot just past it's max setting where it isn't regulated and the output depends on the voltage applied. You can hit that high but only if you use 2 cells that are 3.2V rather than 3.7V. The 3.2V cells fully charged give somewhere around 3.6-3.7V each but you MUST charge them correctly as they will charge up like a regular 3.7V and then blow the diode.
I can't remember what the driver was set for but I have one mits 500 that peaks at 1.3W on start. Just got lucky. Actually went through all my units today cleaning all the shiny ones and fired it up a couple times. Always wonder if it's going to blow but so far so good.
Noticed that the seller (think it's laserlands) that was selling 10 for about $20 keeps jacking their prices up. The guy in the states has more of them though when I looked today. He also has those 150mW 405nm diodes too. If I remember correctly I think they need about 155-160mA to hit 150mW. Give them more and poof. Both of those diodes burn nice and there's nothing wrong with building a few of each with acrylic lenses for cheap. I've probably built 5-10 of the 405nm and easily more than 20 of the 826nm. Just pick some up for when you get bored and feel like building something.

Hi Pman,
My first build was done with one of those 150mw 405's from that seller. Are you talking about lpc826's 10 for $20? If so, please post a link. Cheapest I found 10 is for $40+

I agree, my Mits. "Sinner MS-SSW" build has been going strong (~1.25W) for quite a while now using an AMC 7135 set at 1.4A. The Mitsubishi diodes seem to tolerate this driver rather well. :yh:

Hi Bow,
Got to love that fat, nasty beam! Very nice build you have there,
Thanks for the link
