[PSUBS-MAILIST] LED Lights

[Seaquestor via Personal_Submersibles]

Hi Cliff, maybe Phil could chime in on his led he demonstrated at his shop for use on the deep workers. It had only a flexible membrane over the oil compensated led housing. I think his design is about as compact as you can get, and I recall it had now fins, but run a voltage up to around 200+ volts. Seems to me that simpler the better, is the idea here. For me I will testing my design hopefully next week. with 4 leds, wired for high and low. Based upon alum cost, machining, leds and  subconscious connector I'm coming in around $500 for each light. Cost may drop with multiple units. But one off is always more expensive.

For anyone that has a large LED or halogens on their boat, can you share your experience on narrow beam vs flood lights.   Building a LED housing to be low profile to fit in a FRP recess is going to be difficult with a reflector to get a narrow beam.  As an example, a typical reflector size for a Vero 29 is 110mm (4.33") diameter and 67mm (2.64") deep.  This is massive and you still need housing and heat sink fins.
I am wonder if we really need a focused light or is a flood light adequate?
