Source of light
There are three powered LED diodes Cree XM-L providing 3600 lm used in FINN LIGHT 3600 series. They shine with cold white light 6300 K and guarantee 10 000 hours of permanent usage. Exceptionally effective optics concentrates the light in 10° angle and gives the optimized shape of beam! The spot of light allows the effective signalization to your dive partner.
There is a proved, tried and tested electronics inside. The user can choose the mode of operation for his dive: full performance 3600 lm with running time 5 hours, 1800 lm for 10 hours or the safety mode 360 lm. In the safety mode it is possible to use the lamp on the surface (for preparing of gear or in dry caves for instance) and it shines up to 50 hours. The lamp is being manipulated with the improved magnetic ring on head. The first turn of the magnetic ring in any direction switches the light on 360 lumens mode. Another turn in clockwise direction swiches the light into the stronger mode (1800 lumens). You'll get full power after third turn in the clockwise direction. Turning counter clockwise will lead to the reverse procedure
With the overheating protection the electronics protects the lamp against the damage and the user against the consequence of the accidental switch on out of the water.
Li-Ion batteries are ideal source of energy for the LED. The electronics protects the batteries against discharging and the clever charger against overcharging. The batteries has no memory effect that means you can leave them on the charger during the night. Li-Ion batteries provides enough capacity for the long running time keeping the lamp small sized and lightweight.
Material and construction
The new head construction makes the switching easier. No more searching for the small button in the dark. The magnetic ring stops in accurately defined positions when changing the light modes. Cooling ribs on head create the unique design of FL 3600 series.
With combination of heavy duty delrin and aluminium alloy covered with the hard eloxal coating the lamp is intended for the use in extreme conditions.
FINN LIGHT lamps comply with qualifications of European Standards and possess all important CE Certificates.
