CustomDUO modules


  • Latest high power Cree XP-G2 s3 5500k LED 

  • Reflector provides smooth far reaching beam 
  • Easy fitting via a screw in mes bulb base (replaces halogen bulb, discarding original Petzl Duo reflector)
  • No power drain when switched 'off' with batteries connected
  • Works with Customduo Side modules or Petzl Modu'led 14 (or other Petzl Modu'led with less LEDs) 
  • Single power setting, simple on / off operation
  • choice of 156 lumen (350mA) or 285 lumen (700mA) light output *
  • Ideal, low cost complement to Gecko Side module or Petzl modu'led14 
  • 6.0 volt maximum input


Gecko Spot modules offer an effective upgrade to the standard Petzl Duo, largely because the original halogen bulb reflector combination (or LED replacement bulbs) are ineffective. 


Single LED spot module, fitted in halogen position replacing original Petzl reflector. Reflector provides a far reaching beam. Ideal for checking a deep pitch or high aven. Can be used in conjunction with the 14 LED Petzl Modu'led or with Gecko Side Modules.  



Gecko Spot module incorporates basic thermal protection. Current control circuit will self regulate if module reaches threshold temperature. For good battery and thermal management we suggest only using 700mA setting as an intermittent spotting tool, complimented by a Customduo 'Gecko Side' module. For sustained operation of Gecko spot module we would recommend using the 350mA setting as best practice. 


* Select either 285 lumen (700mA) or 156 lumen (350mA) light output, easily configured with on board jumper plug. Note, high output 285 lumen spotting beam will drain AA batteries quickly and is not intended for continuous operation.
