T-350 Module




Retrofit LED module for Princeton Tec-40 and Impact XL dive lights (often used by cavers as back-up lights)


High efficiency Cree LEDs, 5000k neutral tint providing 130 lumen


Sensible power setting, providing excellent balance between light output and battery duration


Sustainable 350mA regulated driver circuit


Diffused spot optic, optimised for caving  


Long, slow death once cells cannot sustain regulated current 


Easy fitting, just 'flip in' and go (well, almost, see module fitting guide) 


Better performance than the latest LED incarnation of the Princeton Tec-40, the Impact XL (65 lumen)


NiMh or Alkaline (6v max.) 














Princeton Tec 40


The PT Tec40 incorporates a PF halogen bulb producing 28 lumen, with fairly hefty battery cosumption. It is still available on the PT website, albeit with a slightly styled up body from it's, widely used, original incarnation (as shown above).


The latest LED version of the PT-40, the Impact XL produces 65 lumen, with a claimed 50 hour burn time; umhh !!. We are fairly certain that the Flippin Tec T-350 module (for the Tec40) will also fit the Impact XL. Module does not fit the PT Impact, see fitting guide (the model that came in between the Tec-40 and the Impact XL, and incorporated a 5mm white LED and black reflector slug).
