Exclamation Micro Boost DC/DC Driver HELP!

Okay i order'd a PHR-805T & A MicroBoost Driver From Modwerx They Come In Excellent Packaging But The Point Im Getting To is the description of this product says 2.7-6V However When I Finish My Soldering Placing & all that i put My CR123 in My Host & I Get This Tiny Green Light i can barely see! So I Unscrew Where I put My Driver & Take Some Wire hold It To The Power Connector Of the Driver To use A 9v Battery Holding The wire To both So It Comes On But The Beam Is Spread Very Far Out It does Get Warm but why with a 9v it works? & i dont own A Proper Lens module im using a 660nm lens still the beam is not strong the diode is descripted to output 100-120mw I think Im Getting Like 8-9MW WITH A 9v On This DriveR

Driver::http://www.modwerx.com/shop/images/FSCN1122.JPG
Diode::PHR-805T laser diode 405nm 100-120mW [M0025] - $11.99 : Modwerx Shop
Battery http://www.all-battery.com/ProductIm...izer-CR123.jpg

EDIT::The tiny Glass In the diode has shattered

Default Re: Micro Boost DC/DC Driver HELP!

The battery that you linked to may not have enough
current to power your driver.
I would suggest a rechargeable type... You will also
need a lens that will focus your Laser's output.

Contact the seller for information...

Default Re: Micro Boost DC/DC Driver HELP!

9V batteries should really be avoided for everything except smoke alarms or Laserbee power meters or something--portable, low-power stuff. Those 9V batteries are essentially 6x AAAA batteries, and suffer all the limitations that a tiny battery like that carries.

Default Re: Micro Boost DC/DC Driver HELP!

You risk damaging the driver by going 3V+ over the max input. If you read the data sheet is says not to exceed 5.8V and I can tell you they will die with too much voltage.

These cells should work for you.

okay other battery i have is a CR123A Lithium but i said before & thanks for the suggestions but my little glass the tiny glass on in the diode has shattered & there is nothing i can do but im never going to buy a Driver like that Again but i know now that the diodes are very sensitive thanks to me breaking one So next time i order a diode ill know not to let it roll off my desk or have some neodymium magnets under it.

I would suggest that you read the build tutorials and
the FAQs on the Forum...
You will be spending a lot less $$ once you know what
you are doing or doing wrong...

Here is the datasheet. http://hacylon.case.edu/ebay/laser_d...1%20manual.pdf

The input voltage is listed as 2.7V-5.5V and I can tell you from experience you can kill the driver giving it over 6V.
