Review: They are very bright and work well in my camper - Long lasting and bright very happy
Review: Very nice bulbs - Reviewed by Mr C. I was looking for 12 volt LED bulbs to supplement our backup lighting when we lose power from storms. These caught my eye because of their size and wattage. Being a little smaller than standard bulbs leaves more options for fit. At 4 watts each allows for longer run time as opposed to brighter/higher wattage ones calculated for current draw vs amp hour rating of an AGM battery down to 50%. The color temperature is comfortable at 3000K. Lumen output is plenty adequate for our needs in a large or small room during a blackout. Thanks to the reviewer who posted his power supply readout, showing these bulbs drain even less than I originally estimated @ 12V.. They arrive nicely packaged in semi-rigid foam and sturdy box.. Will purchase again as needed for more projects. .

### ⭐⭐⭐⭐⭐ Beautiful vintage LED bulbs that have perfectly transformed my low voltage lighting setup!
*by A***S on November 30, 2025*

These LEMENG 12-volt LED Edison filament bulbs have been absolutely incredible for my RV and off-grid lighting needs while delivering authentic vintage aesthetics with modern efficiency - the quality is outstanding with genuine filament LED design that creates warm, inviting light exactly like traditional Edison bulbs but with the reliability and energy efficiency essential for 12V systems, and I love how the durable construction handles voltage fluctuations and constant use without flickering or premature failure. The functionality is phenomenal as the 4W power consumption provides excellent illumination equivalent to much higher wattage incandescent bulbs while the AC/DC compatibility works perfectly with both RV electrical systems and solar setups, plus the 3000K warm white temperature creates that cozy, comfortable atmosphere perfect for living spaces. They look absolutely gorgeous with authentic vintage styling that adds character and charm to any space while the visible filament design creates beautiful ambient lighting that's both functional and decorative, making them perfect for pendant fixtures, chandeliers, or exposed bulb applications. At this price point for quality LED vintage bulbs designed for low voltage systems, it's incredible value compared to expensive specialty RV lighting or constantly replacing standard bulbs that aren't designed for 12V applications - these have completely upgraded my off-grid lighting experience by combining energy efficiency with beautiful aesthetics that create the warm, inviting atmosphere I want while operating reliably on limited power systems, making this one of the smartest lighting investments for anyone using 12V systems who refuses to compromise on style and ambiance for the sake of energy efficiency.
