cubapro PHAD 4 Torch LED is revolutionary for today’s generation & is quickly becoming the standard in diving torch technology for the future. SCUBAPRO Phad torches use PWM technology Phad torches use a much more advanced eletronic method, using a microprocessor inside the head to control LED. PWM (Pulse Width Modultaion) is controlled by the microprocessor & provides: Perfect battery management, preventing damage by deep discharge. Controls the LEDs at their perfect running current & at their maximum capacity without overload Allows longer burn time because no wasted energy Protects the light head against overheatding & controls the temperature so you can use your dive light underwater & on the surface Incorporates a ‘soft start’ meaning the light is a bit less bright during the first few seconds when turned on, but then it maintains a much longer & brighter burning time compared to resistor LED lights. With PWM technology dimming, strobe & SOS light functions are possible. SCUBAPRO Phad torches have FPH technology FPH is FLOOD PROOF HEAD Technology. SCUBAPRO is the first in the diving market with this fantastic teature! This means, if a diver is changing the batteries, or connecting the umbilical, & drops the head into the water--NO DAMAGE to the HEAD!! Or if a diver accidently opens the head from the body underwater: Again, NO DAMAGE to the Head (only the body will need rinsing & the batteries replaced). FPH makes Phad lights virtually accident proof! Electronics is completly protected LED bulb is completely protected Even bad maintenance of 0-rings cannot harm the light SCUBAPRO Phad torches are modular Phad 4 can also be combined with our Module light battery pack, with each other or with the umbilical cord option for ultimate comfort & convenience. Hook up the head to the umbilical for an easy to manipulate light-weight torch in your hand & keep the heavier battery pack in your pocket.
