here is a quick summary on the highlight of the 2D80 and CSM360 Feilong lights:
*Highlights (2D80 improvements in the new edition)
• Bezel with adjustable focus (optional)
• High performance, long distance searchlight (compatible with D80 adjustable focus bezel). 25mm adjustment range, beam angle adjustable from 1-120 degrees. (At a distance of 10 meters, the hotspot size is adjustable from 10cm to 20 meters)
• Compatible with multiple battery type and sizes
• Overheat and over-discharge protection built in
• Both hardware protection and DC-DC constant current protection for the LED emitter, max current at 11-12A
• New reflector design. Reflector area is over 2 times the size of 2D60 reflector, output has been increased to 200% - 300% compared to 2D60
• Circuit utilizing Synchronous Rectification (
http://en.wikipedia.org/wiki/Synchronous_rectification) to improve efficiency in power conversion. Working temperature is 10 – 20% lower compared to 2D60. The circuit efficiency is approximately 92 – 95%. A constant temperature control function has been added, while the flashlight is still protected from overheating, the brightness will not change when the protection goes into effect.
• Eliminated drain on batteries in Stand-by mode. Shut-off is completed by using the forward placed switch.
• Specially designed rack for multi-position placement
• BT303 II battery charger, adjustable charging current. This charger can charge Li-ion or standard batteries. Available with 10W solar panel for charging in the outdoors. (Optional)
• Fitted tool box can hold BT303 II, D80 bezel, 10W solar panel, batteries and other accessories
• Massive heat sinking surface, 300% of 2D60 heat sinking surface area.
*Highlights (100W LED flashlight, one of the brightest on the market)
• Bezel with adjustable focus (optional)
• High performance, long distance searchlight (compatible with D80 adjustable focus bezel). 25mm adjustment range, beam angle adjustable from 1-120 degrees. (At a distance of 10 meters, the hotspot size is adjustable from 10cm to 20 meters)
• Compatible with multiple battery type and sizes (3 x D size li-ion recommended. Other batteries may not be able to achieve max output or utility)
• Overheat and over-discharge protection built in
• Both hardware protection and DC-DC constant current protection for the LED emitter, max current at 8.4A with working current of 6 – 7A. Total working watt is 13.6V * 8.4A = 114W (approximated). (This LED has max current of 9A, with an official VF of 14.3V, the theoretical max is 14.3V * 9A = 128W.) Due to the high power performance at max output, 100% output mode requires a specific user input. When using 2 D li-ion, the nominal output is at 80%, with 3 – 4 D li-ion the nominal work is 100W.
