Still making them and ..... shooting at 4fps and 1/320
DIY PROJECT ....
if you have the space in your housing and want to use led's that consume more then 20mA (limited now by the CR2032 battery's)
.... you can fabricate this ... i use it now with D810 in Hugyfot housing. Don't forget to put a resistor serial with your led, in this case 39ohm with white and red led!!!!
... although no difference in sensibility between red and white on Sea&sea and Inon strobe. Most off the sensors are in the 600nm range, so red is the best to use.
ALSO very important: the fiber and led are aligned straight and the surfaces of the optical connector are FLAT on booth sides.
