Features: High Efficiency Power LED, 20W White for 3200Lumens. Why does a 20W LED have so high lumen? We use the high efficiency bridgelux or epistar LED chips. Truly high power LED with 160-180lumen/watt for the white. Green and blue LEDs are also brighter than others using SMD LEDs in the same watt. DC5-35V wide input suitable for more batteries. Without the accompanied power adapter, you can connect the light to all DC12-14V Power sources. With the adapter connected, you can power the light with any batteries within DC5-32V. Just make sure your battery can provide enough current or the adapter will trigger battery protection mode and switch the light off automatically since lower voltage needs higher current. Thermal safety switch inside to protect the light from overheating. With the thermal safety switch, you can either use the light underwater or above water. You may dim the light to lower brightness to avoid triggering the thermal switch. Dimmer on the cable! Why dimmable? After the fishes are attracted, high brightness may not result in much bait. Lower the brightness can be helpful for easier baiting. High quality all copper Teflon Cable with Steel Wire inside for endurance traction. Yes, you may never see such a cable before. It is one of the best quality wire cables. All tinned copper for the wire and there is an extra iron wire which protects the cable from broken in strong pull. So feel free to throw/toss/tract the light! High quality aluminum profile enclosure with almost 300g weight. Enough for working in 15Watt above water and whatever underwater since the whole enclosure contact with water.
