I started using these medium screw in base, DCv all voltage LED corn-row lamps. Wow https://www.amazon.com/gp/product/B0CPPP3V4L/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&th=1 On our 32Vdc and another 24Vdc boat, these are great. Way better than the usual incandescent lamps we have had to settle with these many years. I just ordered 6 more lamps, 2 x 3 pack.
Thanks, those are the only ones I couldn't find in LED. Sunseeker uses the incandescant ones in engine rooms until somewhat recently and the vibration always makes the incandescant ones live a short life.
As my backup ER lights die, they will be replaced with these also. Having fun with these in our closets and heads first. Drawback of these lights, now all the dirt, dust, kat hair balls are visible. These lights are not dim-able.
