Greetings,

For those who might be interest in building their own reflectors, I am
offering this design based on a T-12 (1.5") fluorescent bulb.

Also, note that you can decrease the off-angle light emitted by the
sides of the bulbs and striking the water surface by extending the
length of the side wings slightly. ~ 1/4" - 1/2".

This design was based on a particular hood depth that prohibited the
longer length from being implemented.
