I needed a convienient light for the printer and found this on Amazon https://www.amazon.com/gp/product/B07F3WLZV7/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 for $13.00 (or two for $19.00). I liked it, as it was relatively cheap, 24V, swivel adjustable, aluminum frame, good reviews and had a built in on/off switch. I didn't want a light with a separate plug in, power supply, etc. The 14"wires need to be extended by about 10". The wires can be placed in the outer groove of the frame the power supply is attached to, behind the PS and run into the bottom of the PS where there are two free 24V, + & - terminals. Quite handy. Slides into the back of the top rail with the switch and wires on the right side handy to the power supply.

Printing:
I printed it with 0.2 layer and 50% infill. I rounded off the lower portion of the track rail so no support is needed. Placed at 45 Degree angle to fit the @ 9" length on the bed.
