You can apparently see these things from 15kms away, so I assume extremely high. they are the lights that light up Rogers arena and the new Bay bridge in San Francisco

There are 50 modules per strand and I think there are 8 leds per module
17,004 cd / m2 lumens per module. Can not find par and I have no idea what lumens I should be at for a reef tank etc , hence why I need advice.
One strand of these lights are around 1200.00 bucks, willing to part with enough for someone else to make a light themselves in exchange for helping.
