Review on 💡 2 Pack - GRV Ba15s 1156 1141 High Bright RV Car LED Bulb, Cool White, 24-5050SMD, DC 12V by Daniel Bruce

I bought 4 of these bulbs for my RV (to get rid of the energy intensive 1141 and 1156 bulbs. A standard 1141 RV bulb uses 18.4 watts, produces 264 lumens and is VERY hot). They work. excellent, with a light output of 360 lumens and a power consumption of only 2.9 watts (measured) at 12.6 V. These are very high-efficiency lamps with a light output of 124 lumens/watt. High efficiency LEDs typically have a luminous flux of 109-137 lumens per watt. I think efficiency is important when used in RVs and trailer campers, especially dry camping. They also run much cooler than the very hot incandescent bulbs they replaced. The lamps performed well in every respect with a pleasant color temperature of 4000K.
