Phr-805 led?

So today I got my new PHR-805 from odicforce in the post, and I got my 104ma ghostdrive2 (not sure, dont have a test load, but it should be 104ma) and soldered the 2 together, I shorted out the cap beforehand, and the pins were nice and long and I didnt have the soldering iron on it for too long, so it probably isnt voltage spike or heat problem, but anyways, I then connected the whole thing to a 3 AAA battery holder (with the batteries in) and the diode lased but at a very very dim level, like it was really hard to see, then I put a lens on and the dot is soo dim, you can hardly notice it.

Before this, I had a PHR-803 and that also died, this one isnt dead but its not lasing as it should. What is the problem? should I give it more voltage (4.5v atm) or what, cause I cant afford to keep killing these diodes, this is my 3rd diode dead, I hope it isnt LED'd, it should be working, but I cant figure out the problem.

This diode looks like it is lasing at 0.001mw, it's soooo dim. Could my driver be putting out more than 104mA?

Anyone any ideas?

Thats a linear driver your need more votage to keep the driver in regulation and power the diode

this is copy and pasted from Ghost site

The GhostDrive2 is a full featured, micro-sized, linear driver. It's small enough to easily fit inside of an AixiZ module, and is capable of running laser diodes on two 3.7V lithium-ion batteries.* Each driver comes in a preset range which is selected at checkout.

Don't see a current that suits your build? Need more current? Less current? Not to worry, just go to the contact page and let me know what you'd like your drive set for, and we'll get a dialogue going before you hit the buy button.

The GhostDrive2 is also available in the "Option-X" configuration which enables you to customize the driver to your own specifications by supplying your own resistors.**

Installation





Heatsinking is recommended when operated at higher currents.



Warning: The capacitor on the GhostDrive2 must be discharged BEFORE you attempt to hook it up to your laser diode. Failure to do so could result in damage to your laser diode. To discharge the capacitor, make sure the driver is disconnected from it's power source, then short the driver by touching each end of a piece of wire to both the LD+ and LD- terminals at the same time.

*High-powered blu-ray diodes (12X) may require more than 7.4V if powered over 250mA. Do not exceed 15V.

**The driver will not function without its resistors. By choosing the "Option-X" configuration you are agreeing that you have mad soldering skills, understand that you must supply and install your own 2010 SMD resistor, and that you assume all responsibility for modifying the driver. The "Option-X" configuration is not covered under warranty, and refunds will not be given if you choose this option.

I did NOT ask him for permission to do so if there is a problem with this post I be happy to delete or edit. Hope this helps

yeah, I also have a red LPC-826 that works fine off 3 AAA's, and its using a ghostdrive too. If I hook it up to say 7v, will it work?

EDIT: It works! Dam, I was sooo stressed, I switched it on with 2x 16340 and its lasing properly now. Thanks for your help^

READ the instructions you will need 2 3.7V batt. PHR's need over 4V the driver is going to need at least 1.5V so yea your needing some more V.

Sorry don't mean to sound harsh, but you got over 600 post here.

I want this build to turn out for you after 1 blown diode you should have gotten this by now.

yh its just I havnt had much experience with 405nm, and I thought if my red could work with 4.5v, then so could my 405nm, but I was wrong, thanks for your help.

No worries man. I meant to tell you your avatar is boss. Let me know how it works post some pics.

Thanks man, +1, it works fine, just need to cram it into my tiny host, heat sinking is good, it barely gets warm after 2min, I took lots of pics during the whole thing, so I will post build thread later
