Hi Hugh,
I was just looking at a downlight at
Jaycar
It says this light produces 300 lumens from 5
watts.
They sell different angled reflectors to add to
some of their lights.
Do you or anyone know the prefered reflector angle
(beam angle)
Car lights put out round 1000 lumens so I'm
wondering what lumens the
50 watt LED's you're waiting on
produce.
Jay, you mentioned directing lights at an angle
from your centre of vision
in low visibility conditions. Wouldn't just dimming
the lights work the same?

Hi
Jiim, Take a bit of time. I am waiting for samples of 50 watt
LED?s and also some Car headlight LED?s and IT is not much problem to knock
out a housing.
I
don?t plan on spending any more than $250. Scotttish heritage and a
Jewish nose. J
Chs, Hugh

You're right! It's between $3,700 and $4,200 depending on
which way I go!
Since it's a life-long dream to do this I'm not stopping
now!

lighting.

What
about Deepsea Power & Light they make a battery for just what we use
them for subs and the make very good lights for the subs also.

One of the golf cart battery dealers locally said
that the 12v.
designs do not hold up like the 6 and 8 volt because
of the thinner
plates.
