Review on 🔆 High-Performance 12 Volt Replacement 921 Wedge Dome LED Light Bulb for RV Camper Trailer Motorhome 5th Wheel and Marine Boat (4 Pack, Natural White) by Bryce Marshall

I bought these bulbs to use "GRV T10 LED Light Bulb 921 194 24-5050 Super Bright Cool White DC 12V SMD Bulb" (https:// www.amazon.com/gp/product/B00FPFICIW/) which I used in my RV. GRVs kept failing in less than two years of operation because input voltages over 13.0 VDC caused them to overheat. Our RV voltage is 13.6VDC with fully charged batteries or shore power. I realized that I need LED bulbs with a voltage regulation circuit. According to this product description, SRRB lamps have a "wide operating range of 12-24 V AC/DC" with "an integrated DC IC that withstands current fluctuations and ensures long life of the LED chips". Bonus, the SRRB bulbs are noticeably brighter than the GRV version. In the attached photo, the SRRB bulb is in the left socket and the GRV bulb is in the right socket. As you can see, SRRB puts out significantly more light. Also, I like the fact that the entire block is sealed to protect the circuitry. They're installed in pendant lights above my RV's kitchen counter, so they're exposed to vapor and grease in the air. And finally, they seemed to slide into the lamp base more easily than the old GRVs. My only complaint is that I have to buy them in packs of four, which is a shame as I only needed two. Can't comment on durability but I hope these lights will last a lot longer than the ones I've used before.
