Can you power a BR without a driver with low voltage?

Sure you CAN,

But why would you want to risk your diode to have a violet LED?

Just get an LED.

They're cheaper.

Peace,

lol. ok

I got another ? What is the difference between a green driver red driver and BR driver? I got a driver for a red green laser and want to hook this BR diode up to it. will it work? if so what side should i use the green or the red?
 
The current/voltage output and current/voltage inputs will be different. Though for red and green they will have similar characteristics .

Without seeing the driver, I'm going to say, "No." The kind of driver it appears that you are referring to, is for DPSS lab style modules. It will put out more current than the violet diode can take. What violet diode you have will dictate how much current to go for, but they all want less than 200mA. Most of them can only take much less than that.

Sorry but i dont understand. Are you saying that the drivers are completely different? The driver I have has 2 pots on it one for green and one for red. Both wont work for BR? Even though the driver calls for 5v-12v input. I don't know what the output is though. I think that the green side is much higher then the red. its this driver

Unless someone has measured the current of this, I am still going to say, "No." The voltage into the driver is not the issue. The current coming out of the driver is. There is no spec sheet for it, but red diodes pull between 300mA-500mA. Green modules pull even more than that. Violet diodes pull less than 200mA. The current coming out of the driver will kill the violet diode.

Peace,

Do a search in the forum for the words "dummy load"

Peace,
dave
 
Yeah the dummy load will be a good judge of the characteristics of a blu ray diode. If the voltage coming from the driver is too high you can try a series resistor to consume some voltage.
 
Couldn't you use a DMM? Seems like it would be easier than hooking up a dummy load.

P.S, Really bad thread title. :-/

The driver needs to be under a load to get an accurate measure of the current (and to avoid damage to some of them).  You use the DMM to measure the current across/through the load.

Somebody with better electronics knowledge will jump in here sooner or later ;)

Peace,
dave
 
You may already know this, but in order to measure current with a multimeter you have to connect the meter in series between the positive output of the driver and the diode's (or dummy load's) positive pin. If you don't insert the meter into the circuit like this, then the reading you get will be inaccurate.
