Novatac Spec Ops mod question?

Flashlight Modding and DIY Parts

Hi all,

Just a question for anyone who might have already tried, so I don’t needlessly fry a 519…

Preface:
The Novatac Spec Ops has a different voltage range than a standard novatac, accomodating up to 2 fresh 3v Lithium primary cr123’s. I believe that when stock, it uses some version of the SSC P4, but not sure if there are 2 different voltage versions of the LED, or if the circuits just buck the voltage down similar to a standard novatac. According to the manual, the circuit’s operating range (input) is between 4V-6.5V, I’ve not tested what happens with a single LiIon below 4V.

Question:
Would a simple LED swap with a 519 end up cooking the LED, or should it buck down to a standard Novatac output V-led?

Thanks in advance!

afaik, if it can use SSCP4, it can use 519a.. regardless of the driver battery compatibility

I look forward to your successful mod :wink:

Sweating in multiple calibers as I’m psyching myself out.

So aside from the fact that the SSC P4 is part number for some small LED display, I appear to have found a spec sheet for the LED in question:

Page 13 indicates bins from 2 to 4.25V, but I am assuming the more extreme ranges are for red/blue LEDS.

Pg14 onwards has tables listing various white LEDs, from my skim read, it appears all the white LEDs are vF bin H, I, J, K, ie 3-4V…

Thanks! This info is most reassuring and helpful
