.... and also 3000k WARM Cree XP-G3 s3 LEDs providing minimum of 156 lumen/watt



Omni v5 



The Omni v5 is the most advanced of our LED conversion modules available for the Petzl Duo.


The v5 features the latest s3 bin Cree XP-G2 LEDs, delivering potential light outputs of up to 570 lumen, and offers user programmable power settings. The spot and flood LEDs can be operated separately, or blended together at a range of power settings, in a sequence that best suits your individual needs.  






Twin high power s3 XP-G2 LEDs (156 lumen @ 350mA @ 85 degC) 5500k neutral tint, as standard


Smooth spot optic for distant focus & flood LED (with efficient optic for forward bias), for maximum usability.


LEDs operated separately or blended together.


Programmable; range of power combinations (see table below) to best suits your individual requirements.


570 lumen output (combined high spot 285 lumen and high flood 285 lumen).


Battery charge level indicator. Red SMD LED will blink 1-5 times to indicate battery charge (5 flashes being 'full charge'). Visible on hand held in front of lamp. 


Super robust circuit architecture. Custom heat sink, and discreet thermal management.


Very simple fitting; push fit directly into existing Duo pilot bulb connections. Will work with any Petzl Duo.


No power drain when lamp is switched 'off' with batteries connected.


6.0 volt maximum input.


Progressive dimming at end of battery charge, i.e. lamp will not just shut off when batteries are flat and cannot sustain full output.



Output lumen figures provided are for XP-G2 LEDs (@156 lumen/watt). Output figures for new XP-G3 LEDs (@172 lumen/watt) will be proportionally higher. 












Operation (factory default settings)



To switch between the four default power settings (see following table), in a looping sequence, use the down switch on the Petzl Duo. Switch on-off-on to sequence between settings 1-2-3-4 ... 1-2 etc.


'Double switch' to operate moon mode (10mA flood), i.e. (swift double operation of switch, i.e. on-off-on). The red indicator LED will blink 1 to 5 times to indicate battery charge level. Lamp will run in moon mode until next switched off. 


Omni v5 features 3 second 'last' mode memory. When the lamp has been on for more than 3 seconds in any setting and is switched off; when switched back on it will automatically restart in the last used setting. 


Output lumen figures provided are for XP-G2 LEDs (@156 lumen/watt). Output figures for new XP-G3 LEDs (@172 lumen/watt) will be proportionally higher. Output figures below could be anticipated for latest s3 3000k warm LEDs.
