Oh, I've been down that road with our RV! The lights were so dim it was like cooking by candlelight. Swapping out LEDs is pretty straightforward once you get the hang of it. Brightness for LEDs is measured in lumens, not watts. So, the higher the lumens, the brighter the light. I switched to a bulb with more lumens, and it was like night and day in the kitchen area.
When I was hunting for brighter bulbs, I didn’t just look at the lumens; I also considered the color temperature. A cooler white can sometimes make things seem brighter than a warm yellow. If you need a hand figuring out what you need, check out https://leds.to/ for a guide on brightness and color temps. Helped me find the perfect balance without making the kitchen feel like an operating room.
