Derek, I dont have a Boler
but on my Scamp
I find having a LED three light bar on the underside of both sides of the kitchen overhead bins is far better than the original single light fixtures that Scamp
had mounted on vertical surfaces in the kitchen area (one near the sink and the other at the end of the overhead) - in particular the one located on the end of the overhead facing the table area is pretty well useless.
I originally had a light in the roof over the table area but sacrificed it for my Fantastic fan. In hindsight that light was pretty effective and had I not already had a large hatch in the roof forward of it and could have mounted the Fantastic Fan in a slightly different position I dont think I would have sacrificed it. I have though lights on either side of the table mounted under the overhead bins (both two fixture/bulb LED's) that work pretty well for lighting
up the table when in use and work well for reading at night. Have also seen a number of Boler's with rear overhead bins or shelves that you mention and lights mounted on the underside that seem to do a pretty good job as well - if I had a rear bin/shelf I would would put a light under it as well.
When shopping for LED's look for a high Lumans rating as that will make or break it.
LED Bulb brightness in Lumens comparison:
A 60 watt incandescent bulb is rated at approximately 800 lumens
A 40 watt bulb is rated at approximately 400 lumens
A 25 watt bulb is rated at approximately 180 lumens
