Im trying to build an LED dive light, I am good with the mechanical side of making everything, but outside of knowing how to solder I really have no clue about circuitry. Hopefully some one out there can help spell this out for me.
I was looking at using at least 3, possibly 5, of the Endor Rebel, tri-emitter led that produce 435 lumens @700mA. I was thinking of powering these with a 700mA buckpuck.
Can I connect the LEDs in parrallel with this buck puck, will it keep up with the higher current draw of the total LEDs?
I would think if I connected the LEDs in serial the voltage requirement would get extrodinary, the forward voltage of each led is 9.45volts, so inorder to connect 5 together they would need to have a 47.25 volt power source right? so that is out of the question.
I was thinking of using a 14.4 volt, 10000 mAh Nimh battery pack. Unless I am completely wrong, which I most likely am, the LEDs should draw 3500 mA right, so it should give me on the better side of 2.5 hours burn time right??
The battery pack is going to be in a seperate cannister so it will be over 18in away from the buck puck (in the light head) so I need to use a 50v capacitor across the input voltage terminals in front of the buck puck, and I was going to use a push button on/ off switch right after the battery.
Does any of this seem crazy, it probably is...
thanks in advance for helping a newbie out.
