I think you are just asking what style/wattage of 'bulb' to swap out? At that location close under, in-line creating shadows within the scrollwork, angle, and probable type of cabling that is against code, I don't think any different 'bulb' will change much (unless you go red or green).

What might be best, would be to rewire a light towards the front of the shed roof below that is pointed at the entire wall and washes it with a soft light. You could even try a solar-powered landscape-style spotlight, since I'd guess you can't do electrical.

No bulb and remove the socket and wiring. It is no doubt against code.

I was delightfully surprised to learn my new lights in my peaks don't have replaceable bulbs to change. If I replace the build it's fixture and all. What a world!

just buy an LED light bulb in a super low watt warm toned.

I think that what I will do! I bought a relax soft led equivalent to 45 watts, it’s dimmable. I will be climbing the ladder tomorrow! Thanks!
