DC 12V To 85V 12 Watt Super Wide Voltage LED Light Bulb - E27 Medium Base Lamp

I finally finished my basement and wired all of the lighting to be DC. I Ordered these lights 3 different times and the lights have been different each time. Different shape and different color temp. Most of the lights have failed or started to flicker. The components and design is poor quality. I have since removed the pcb and and replaced them with pcb's of my own. I am only using the edison base so i can plug the lights into the can fixtures i installed. I am running a 24v dc battery bank that is charged by a small solar system.

Nice lights, did the job well in my existing lamp fixture - i just had to add a 24 volt power source

These bulbs are being used to retrofit the lighting in a railroad business car that was originally built in 1915. In the 1950 the car was upgraded to 36 VDC incandescent lighting. The lighting load for the coach was over 90 amps in it's current configuration. It will be reduced bu about 85% by the LED's the picture shows the 12 watt LED lamp as compared to a 100 watt 34 volt incandescent bulb. The LED is on the right of the shot. The bulbs fit nicely in the old recessed light fixtures in the coach.
