Limited edition cave photography light
Blind Bat 20/20
Latest version of our Blind bat compact cave photography light, with high capacity li-ion battery. 1000 plus lumen, single power flood output. Operated from 3.7v li-ion battery arrangement capable of providing 3A current at LED. Cree XP-L2 LED, 5000k. Full flood bare LED, with optional drop in diffuser included. One hour plus run time*.
Custom machined aluminium LED lamp housing, anodised finish. Compact, diameter 53mm x 12mm. Lamp body has a 1/4" 20 tpi mounting thread for standard tripod, hot shoe adapter etc. Matching 'Lil Monkey' alloy battery box / tube incorporating 3.7v 3500mAh cell (not compatible with previous version Blind bat lights).
Simple operation, connect lamp to battery to operate. Lamp is thermally limited, which will be most apparent if operated for extended period, for example if filming (even over short periods as produces a fair amount of light output and associated heat). Output will drop automatically when too hot, and steps back up once it has cooled down a little. Or simply disconnect from battery and allow time for Blind Bat to cool down of course. Water resistant design, so cooling can be accelerated significantly by dipping in cave water !! Not depth tested but has lamp front window O ring, waterproof cable glands and waterproof inline connectors between lamp and battery box. 4.5mm diameter cable.
Supplied with charge adapter lead, for charging with Rude Nora micro USB charger. Rude Nora micro USB charger available separately, as chances are that you may well have one of these already.
Note, photos (left) illustrating camera and tripod mounting are taken from previous version of Blind Bat! The Blind Bat 20/20 uses the same housing, and can therefore be mounted in this way too, via the mounting thread.
* lamp kept cool in water to avoid thermal regulation of output
