Alpha Test: Fluorescent to LED retrofit

I accomplished my first retrofit of the boat's fluorescent lighting.  I performed the alpha test to night.  The red light looks OK but the Warm White lights look like they are not diffused sufficiently.  I guess it is back to the workbench tomorrow to add a few more modules to try and make the light look a little more uniform.  All in all I am happy with the test but want a better look. Currently I have 6 white and 5 red modules mounted on a piece of Aluminium flashing.  The red string is not intended to be bright by design.  The white I want as bright as the circular 9W fluorescent tube.  At present iot is not quite as bright and it is a little warmer than the fluorescent: I am guessing at about 3000°K.

The LED were purchased on eBay in strings of 20 modules and each module has 4 LED's.  The module input is 12VDC nominal and there are 4 LED's per module arranged in each corner of a 1.5" square.  I have not made any current draw tests yet but the fluorescent draws 0.7Aand the LEDs about the same. More on this project later as I go into Beta testing.
