should have the bulbs you are after if they are what I'm thinking. Not the best light though from them in that configuration. How about a fixture swap?
I would get yourself a nice 12VDC incandescent reading light of the style you prefer and then get a replacement LED from LED Retrofit Lights for RV Reading Lamps
. Reason being is that EVERY LED reading light I've seen to date for RV use has been junk. They might be out there, but I haven't found them. We had great reading lights in our prior camper, and boon-docked a lot and I was very please with the M4 conversions.
As for a reading lamp while sitting, is a battery powered LED book light out of the question? DW always preferred that, and she has a nice one.
