Short answer, No.

If you look here, you will find that for these LED's that Fred is selling, the "nominal" voltage is "T", which is:

T.............6.39V - 6.87V

Bin Codes Explained ...

Now, you can direct drive one of these out of 3 CR123 batteries and it will be VERY overdriven at approx. 1.5Amps becuase the CR123's voltage will drop under load. Even at this level you are severely shortening the life of the LED!. If you were to drive this LED with a bench supply set to 9V's and assuming that the bench supply can provide 3-5Amps, you will kill the LED very quickly :awman:

Will one of these be okay driven at 9 volts?

Will has already given you a perfectly fine explanation of why you shouldn't do that, but I just want to weigh in and suggest that any LED should really be current regulated for just those reasons. It is what Lumileds suggests for all their LEDs, so why chance ruining any LED by using DD?

This is not to say that you can not DD an LED, but it is always risky. You really need to match the LED carefully with the battery voltage.
