Following up on my previous post, here is the direct link to the LEDwholesalers page for the bulb I used. You could probably contact them with any questions.
Iíll also mention that we lived in the motorhome with these bulbs for 4 months as campground hosts powered by a portable solar suitcase and a 2000 watt inverter generator as backup. We have used the motorhome in RV parks with our 30 amp cord and at home for guests plugged into 15 amp power. We never had a bulb go out
I feel itís notable that the company is still in business 7 years after I bought my bulbs.
However, Iím sure there are many more options out there today, so shopping around is wise. I just thought I would share our experience
