Hi el mar, thanks. Yes it is bright. A friend of mine was in his boat behind me . He called me on the radio and asked me to turn it off. Lol
The box was existing. It must have been for a different light . Used a Piece of 1/4 inch starboard, cut and routered. Then cut the whole in the center for the led. used pieces of teak cut like a wedge to angle it down to the water. It will work out nice for the nite bite in the canyon.
