I have $220 invested so far for the 2 lights, the 3 will cost me around $270-$280
I bought a 48"x 11 1/2" heatsink from an air conditioning unit and cut it into 3-16" pieces $90, (price went to $140 the day after I bought it)
led= 40- royal blue, 10- blue, 30- 14k $86,
75v drivers cost $7 each, quick silver thermal adhesive $6, wire $8
I still have to order the led to finish my last light, another $43 for the led and $14 for drivers
