Re: [PSUBS-MAILIST] Interior low level lighting

Hi Brian.
 
What voids specifically are you referring to that the mineral oil fills?
 
Bill.

Bill,
           I have a friend who is making exterior LED's for underwater illumination using mineral oil to fill the voids and also as a coolent to cool the LED's that produce too much heat ( when the LED's are pushed with too much voltage they heat up).

I wonder if LED's could be rigged for submergence on the dash of my wetsub? I like John's idea for insuring seeing his switches in total darkness.
 
In the murky water that would be a definate benifit for me in the wetsub. Being able to see the led light next to my switches would aid in making sure 
 
I used the correct ones when in extremely low viz situations. Of course in that viz case, it would be time to terminate the dive due to low viz, but DURING
 
the dive before it was terminated for low viz, it could be a real help.  Any ideas?
 
Bill.

Interesting thread.  I think I'll be sure to bring my forehead mounted trilight: It has red LED's for preserving night vision.  A little off the cuff but this thread got me thinking.
