I have a DC 36 Volt solar system and very much appreciate that 12 Volt Monster has LED bulbs for DC application. During the day when charging, my system gets up to 43-45 volts, so the DC 12V to 85V 12 Watt Super Wide Voltage LED should be just what I need. I have used the old style of this bulb that was large and had vents on the sides, and now I use the new style smaller bulb that has no vents, but has electronic protection which causes the bulb to dim down when the daytime charge gets high, but it has turned out to not be enough protection. If I turn off the bulb shortly after it has dimmed, the bulb is protected. To protect the bulb from burning out prematurely, I make sure it is off during the day while the system is charging. However, one day I forgot to turn the bulb off and the charging voltage caused the bulb to go dim, (which is the electronic protection going into action). I didn't realize until evening that the bulb was on all day. I turned the bulb off to reset the electronic protection, the bulb returned to its normal brightness -- all good. But the next morning when I turned the bulb on, it was unusual bright, then went dim. I turned the bulb off to reset it, but when turning it back on, the bulb burned out. Unfortunate...since the bulb had only been in use for a few months, and they are expensive. So the super wide voltage doesn't seem to be effective enough, as my charging voltage is only going up to 45 volts, and the bulb is rated to be able to handle 85 volts. I hope the bulb can be further improved to handle the daytime charging volts in a solar system.
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.
