      921 bulb equivalents

      Posted by Louis Fuchs on 21st Jul 2022

      This was the second order of LED bulbs I had the pleasure of receiving and installing. I've now replaced/upgraded 40+ bulbs (internal & external) on my RV trailer. Well worth it!!

      It works as specified and is worth it.

      Posted by WA1IDA on 15th Jun 2022

      As a lamp it should light. It sure does! The "Economy" price certaily helps. One might complain about the snug fit in the socket, but if it meets the standard not much can be done. M4 Note: As some original glass bulbs are thicker than others, the LED base is towards the thick side so they do not fall out of looser sockets. Align the tab, press firmly, and rock it back and forth along the length of the tab and the base will pop into the socket.

      SMD light bulb with wedge base

      Posted by henry on 15th Oct 2019

      Definitely brighter than the incandescent bulbs it replaced and I accidently left one on overnight and no perceptible battery drain. If it had been an incandescent, the battery would be completely drained.

      Posted by Unknown on 5th Jul 2018

      Very bright, very white. Only one out of fourteen bulbs faulty. Small power draw. M4 Note: Contact us regarding replacement of any bad bulb. DOAs are extremely rare. Also, ensure the wires on the bottom of the bulb are aligned properly up and away from the side of the base then reinsert into the socket.

      Easy Project!

      Posted by Barb on 12th May 2018

      I have a solar set up for my travel trailer with two batteries. I wanted to replace the trailer's original bulbs with these LED bulbs. Very easy to swap out. Purchased a dozen as I needed 11 bulbs. Nice bright light. Will really help when boon docking.

      Wow!

      Posted by S. Morgan on 30th Mar 2018

      Replaced the bulbs in the light fixture over the dining table in our motorhome. What a difference! Now we can eat and read in comfort. No more heat bearing down, and much better illumination. I love the fact that we are placing less stress on the batteries.
