Found these awesome LED grow lights that are great for turf scrubbers at my local mass hardware store. Much cleaner looking that the clamp-on / CFL / DYI LEDs people typically use for DYI ATS. About 4" x 24" so better for the bigger ATS out there. ~70$ but replaced my DYI LEDs and rusted heat sinks with these... Use two on my 360.
